Fixed the AttributeError crash + +v4.4.2's launcher script crashed on START with: +``` +AttributeError: 'EncoderWorker' object has no attribute 'verbose' +``` + +The launcher script's `EncoderWorker.__init__` never set `self.verbose`, +so when `_check_disk_space` referenced it, the worker thread crashed. +Fixed — `self.verbose` is now set from `env.av1an_flags["verbose"]` in +both the package and the launcher script. + +### 2. UI toggle for av1an + +Instead of the `--use-av1an` CLI flag (which was weird to require), the +GUI now has an **"av1an (chunk-parallel)"** checkbox in the options row +next to "Force (skip validation)" and "Delete source after verify". + +- **Default OFF** (unchecked) = ffmpeg-only, the reliable default +- **ON** = av1an chunk-parallel, for users with a working VapourSynth setup + +The CLI flag `--use-av1an` still works (for scripting), but the UI +toggle takes precedence when set. + +### 3. Fixed misleading "single-file script" terminology + +The docs called `open-transcode.py` "the single-file script" — but it's +a 6,500-line launcher that mirrors the `opentranscode/` package (16 +modules). Calling it "single-file" was misleading. Now consistently +referred to as "the launcher script" throughout docs and comments. + +--- + +# OpenTranscode v4.4.2 — Production Release + +**v4.4.2 kills the live tail spam and the confusing "FAIL then OK" double-status.** + +## What changed + +Two fixes for issues found in v4.4.1 testing: + +### 1. Live tail gated behind `--verbose` (launcher script) + +The package had the live tail (`│ Encoding: 1373/1376 Frames @ 51.70 fps...`) +gated behind `--verbose` since v4.1.1. The launcher script (which the +tests run against) never got that gate — it was emitting every frame of +SVT-AV1's progress bar to the log in quiet mode. Now gated. + +### 2. "FAIL: av1an exit code 1" moved to `_vlog` + +When av1an fails but the ffmpeg fallback succeeds, the user was seeing: +``` +[22/180] file.mkv — FAIL: av1an exit code 1 +[22/180] file.mkv — OK: 1.6MB -> 1.3MB (81%) +``` + +Two status lines for one file — one FAIL, one OK. Confusing. Now the +av1an failure is logged to `_vlog` (verbose only), and the user only +sees the final outcome: +``` +[22/180] file.mkv — OK: 1.6MB -> 1.3MB (81%) +``` + +If both av1an AND ffmpeg fail, the user sees: +``` +[22/180] file.mkv — FAIL: av1an + ffmpeg both failed +``` + +One line. Clear outcome. + +### Note on `--use-av1an` + +The log that revealed these issues showed av1an running — which means +`--use-av1an` was passed. The default (ffmpeg-only) doesn't hit the +av1an concat bug at all. If you're seeing av1an failures, drop the +`--use-av1an` flag and use the default ffmpeg path. + +--- + +# OpenTranscode v4.4.1 — Production Release + +**v4.4.1 shuts up.

No "still encoding" messages. + +**What's gated behind `--verbose`:** +- Heartbeat (`... 30s elapsed`) — was always-on since v4.3.0, now opt-in +- Disk-space warnings (`WARN: low disk space on output...`) — now opt-in +- Live tail of ffmpeg/av1an stderr — already opt-in since v4.1.1 +- CMD: lines, DIAGNOSIS blocks, resolution map — already opt-in since v4.2.1 +- Pre-flight validation table — already opt-in since v4.2.1 + +**If a 10-hour encode looks hung without the heartbeat**, run with +`--verbose` to see it.

Massive-file support + +Three changes to prevent failures on 30GB+ source files: + +**Per-file timeout raised from 2h to 24h (configurable via `--timeout`)** + +A 30GB 1080p BluRay rip at SVT-AV1 preset 6 (~5-10 fps) on a 2-hour +movie takes 4-10 hours. The old 7200s (2h) timeout killed massive-file +encodes partway through. New default is 86400s (24h). Configurable: + +```bash +opentranscode --timeout 36000 # 10 hours per file +opentranscode --timeout 0 # no timeout (not recommended) +``` + +**5%-of-source integrity check replaced with absolute 1KB minimum** + +The old check rejected outputs smaller than 5% of the source size. For +a 50GB high-bitrate BluRay source, 5% = 2.5GB — but valid AV1 at CRF 32 +produces 1-2GB for a 2-hour movie. This caused false "output too small" +failures on valid encodes of massive files. + +The new check uses an absolute 1KB minimum (a valid container header +alone is ~1KB; anything below is definitely corrupt). The real +integrity gate is the duration check in `_verify_and_finalize` (output +must be >= 95% of source duration). + +**Disk space pre-check (warn, not abort)** + +Before encoding each file > 1 GB, the worker checks free space on the +output and temp partitions: + +``` +[N/180] big_movie.mkv + WARN: low disk space on output (5.2 GB free, source is 30.0 GB) — encode may fail partway through + ... 30s elapsed + ... +``` + +When scaling, also checks the temp partition (the lossless intermediate +can be 2-3x source size): + +``` + WARN: low disk space on temp (20.0 GB free, lossless intermediate may need ~60.0 GB) — consider scaling to a smaller resolution or freeing space +``` + +This is a WARNING, not an abort — the user might be encoding to a +different partition or know the output will be smaller. If the encode +fails partway due to ENOSPC, the existing error handling catches it. + +### 2. Reduced log noise + +**Combined status lines** — every file now produces ONE line instead of two: + +Before (v4.3.0): +``` +[1/180] filename.mkv + OK: 1.6MB -> 1.3MB (81%) +``` + +After (v4.4.0): +``` +[1/180] filename.mkv — OK: 1.6MB -> 1.3MB (81%) +``` + +Same for SKIP and FAIL: +``` +[2/180] already_done.mkv — SKIP (already av1/opus) +[3/180] broken.mkv — FAIL: not a valid video (ffprobe could not read it) +``` + +**Disk-space warnings no longer fire for skipped files** — the check +moved after the skip-existing check, so a folder of 175 already-encoded +files produces 175 SKIP lines, not 175 SKIP lines buried in 175 disk- +space warnings. + +**Heartbeat stays user-facing** (fixed in v4.3.0) — one line per 30 +seconds during long encodes: +``` +[1/180] big_movie.mkv + ... 30s elapsed + ... 60s elapsed + ... 90s elapsed +[1/180] big_movie.mkv — OK: 30.2GB -> 2.1GB (7%) +``` + +The `[N/total] filename` banner appears once at the start of the encode +(so the user knows what's being processed), heartbeats fire every 30s +(so the user knows it's alive), and the final OK/FAIL line repeats the +prefix (so the user can match status to file at a glance). + +### What v4.4.0 keeps + +- **Skip-existing detection** (v4.3.0) — probes output with ffprobe, + skips files whose codec matches +- **Live progress tail + heartbeat** (v4.1.1, fixed in v4.3.0) — + av1an/ffmpeg stderr in `--verbose` mode, heartbeat always on +- **`--use-av1an` opt-in** (v4.2.0) — ffmpeg is the default encode path +- **`--verbose`** (v4.2.1) — full tech detail (CMD:, DIAGNOSIS, etc.) +- **`--force-reencode`** (v4.3.0) — bypass skip-existing +- **`--skip-existing` / `--force-reencode`** (v4.3.0) — defaults to skip + +### Usage + +```bash +opentranscode # default: ffmpeg, skip-existing, 24h timeout +opentranscode --timeout 36000 # 10h per-file timeout +opentranscode --force-reencode # re-encode even if output exists +opentranscode --use-av1an # opt into av1an chunk-parallel +opentranscode --verbose # full tech detail +``` + +--- + +# OpenTranscode v4.3.0 — Production Release + +**v4.3.0 adds skip-existing detection + fixes the v4.2.1 heartbeat regression.** + +## The v4.3.0 changes + +### 1. Skip-existing detection (the big feature) + +When you re-run OpenTranscode on a folder you've already encoded, it now +**skips files whose output already exists with a matching codec** instead +of re-encoding them from scratch. + +Detection strategy (all must pass): +1. Output file exists at the computed path (`_archived.`) +2. ffprobe can read it (not corrupt) +3. Video stream `codec_name` matches the selected encoder (`av1`/`vp9`/`hevc`) +4. Audio stream `codec_name` matches the selected audio profile (`opus`/`vorbis`/`flac`) +5. If scaling was requested, output resolution matches the target + +**What is NOT verified** (and why): +- CRF/preset — these are encoder settings, not reliably stored in container + metadata. To re-encode at a different CRF with the same codec, use + `--force-reencode`. +- Audio bitrate — varies per file based on loudness normalization. + +**CLI flags:** +```bash +opentranscode # skip-existing ON (default) +opentranscode --force-reencode # re-encode everything, even if output exists +``` + +**Log output in quiet mode:** +``` +[1/180] already_encoded.mkv + SKIP: already encoded (av1/opus) +[2/180] new_file.mkv + ... 30s elapsed + OK: 1.6MB -> 1.3MB (81%) +... +QUEUE COMPLETE. Success: 45, Failed: 0, Skipped: 135. +``` + +Skipped files are counted separately — they're NOT successes (nothing +was encoded) and NOT failures (the output exists and matches). + +### 2. Heartbeat regression fix + +v4.2.1 gated the 30-second heartbeat behind `--verbose`, which caused +the "hangs on first transcode, forever timer" symptom in quiet mode. +The user saw: + +``` +[1/180] filename.mkv +``` + +...and nothing else for the entire encode duration. Looked exactly like +a hang. + +**v4.3.0 fix**: the heartbeat is **always user-facing** (quiet or +verbose). The live tail of `frame= 67 fps= 12...` stays gated behind +`--verbose` (that IS noisy), but the heartbeat is the "is it alive?" +signal — one line per 30 seconds, not "absurd amounts of useless info." + +Quiet mode now shows: +``` +[1/180] filename.mkv + ... 30s elapsed + ... 60s elapsed + ... 90s elapsed + OK: 1.6MB -> 1.3MB (81%) +``` + +One line per 30 seconds + the success line. Not noisy. Not silent. + +### What the skip detection does NOT cover + +The detection is conservative — if in doubt, re-encode: +- No ffprobe available → re-encode (can't verify codec) +- Output file exists but ffprobe can't read it → re-encode (treat as corrupt) +- Video codec matches but audio doesn't → re-encode +- Codec matches but resolution doesn't (when scaling requested) → re-encode + +This means the only time a file is skipped is when we're **confident** +the existing output matches your current encoder selection. If you +switch from AV1 to x265, all files re-encode. If you switch from Opus +to Vorbis audio, all files re-encode. If you change the target +resolution, all files re-encode. + +--- + +# OpenTranscode v4.2.1 — Production Release + +**v4.2.1 makes the log quiet by default.

It doesn't, +across distros. Failure modes observed in production: + +- **`Unprocessed tokens: --threads`** (v4.1.0/v4.1.1) — `SvtAv1EncApp` + CLI doesn't accept `--threads`, only `--lp`. Every chunk failed 3x. +- **No av1an output for 270+ seconds** (v4.1.2) — av1an wedged at + startup or its stderr is buffered and won't flush until exit. +- **y4m pipe breaks** (v4.0.0) — Hybrid chunk method fails on phone- + recorded MP4s with sparse keyframes. +- **VapourSynth plugin issues** — `lsmash`/`ffms2`/`bestsource` are + separate packages that most distros don't install by default. + +Each fix uncovered a new failure mode. The pattern is clear: av1an is +too fragile to be the default. + +### What changed + +**Default encode path is now ffmpeg-only.** The av1an pre-flight smoke +test is skipped entirely. `_on_run_clicked` sets `use_ffmpeg_fallback = +True` directly, and `EncoderWorker` runs the `_ffmpeg_fallback_encode` +path for every file. + +This means: +- **No VapourSynth dependency** — ffmpeg invokes `libsvtav1` as a + library, no `SvtAv1EncApp` subprocess, no `libvapoursynth-script.so`. +- **No chunk-method selection** — single-pass ffmpeg per file. +- **No `--threads` CLI quirks** — `-threads` is a valid ffmpeg/libsvtav1 + library option. +- **Immediate progress output** — ffmpeg's progress bar flushes to + stdout line-by-line, picked up by the live tail (v4.1.1). +- **Slower than chunk-parallel av1an** — single-pass, no scene-split + parallelism. But it actually completes, which is the only thing that + matters. + +### The `--use-av1an` flag + +Users who specifically want av1an chunk-parallel (e.g. they have a +known-good VapourSynth + lsmash/ffms2 setup) can opt in: + +```bash +opentranscode --use-av1an +``` + +When set, the full av1an pre-flight + smoke test runs as before, and +the encode uses the chunk-parallel path. When not set (default), the +smoke test is skipped and ffmpeg is used directly. + +### What v4.2.0 keeps + +- **Live progress tail** (v4.1.1) — ffmpeg's stdout/stderr emits to the + GUI log as it arrives, with `\r` progress bar handling. +- **30-second heartbeat** (v4.1.1) — `... still encoding (Xs elapsed)`. +- **`--max-workers` / `--threads-per-worker` CLI flags** (v4.1.0) — + still wired through `env.av1an_flags`. `--threads-per-worker` is now + actually useful in the ffmpeg path (libsvtav1 accepts `-threads`). +- **`--chunk-method`** (v4.0.0) — still honored when `--use-av1an` is + set. No-op in the default ffmpeg path. + +### What the ffmpeg command looks like + +``` +ffmpeg -i input.mkv \ + -c:v libsvtav1 -preset 6 -crf 32 -pix_fmt yuv420p10le -g 240 \ + -c:a libopus -b:a 64k \ + -y output.mkv +``` + +Simple, reliable, no surprises. The same command works on any distro +with `ffmpeg` compiled against `libsvtav1` (which is the default on +Arch, Debian, Ubuntu, Fedora). + +--- + +# OpenTranscode v4.1.2 — Production Release + +**v4.1.2 reverts the `--threads N` injection that broke av1an in v4.1.0/v4.1.1.** + +*(Note: v4.2.0 makes ffmpeg the default, so this av1an issue is no +longer reachable unless you opt in with `--use-av1an`.)* + +## The v4.1.2 fix (the actual root cause) + +### What was broken + +v4.1.0 added "intelligent chunking" that injected `--threads N` into +av1an's `--video-params` string, intending to cap each per-chunk encoder +instance to N threads. The theory was sound — without a cap, SVT-AV1's +default `--threads 0` means "use all logical cores," so 13 chunk-parallel +workers × 28 threads = ~364 threads on a 28-thread Xeon → kernel +scheduler drowned → hard lock. + +The implementation was wrong. av1an invokes `SvtAv1EncApp` (the +standalone SVT-AV1 CLI binary) per-chunk, not the libsvtav1 library. +**`SvtAv1EncApp` does not accept `--threads`** — it uses `--lp N` +(logical processors) instead. The result, visible in the user's log: + +``` +Svt[info]: ------------------------------------------- +Svt[info]: SVT [version]: SVT-AV1 Encoder Lib v4.2.0 +Svt[info]: ------------------------------------------- +Unprocessed tokens: --threads +Unprocessed arguments: 6 +Error in configuration, could not begin encoding! +``` + +Every chunk failed 3 times with this error → av1an exited with code 1 +→ no output file → OpenTranscode fell back to ffmpeg → ffmpeg succeeded +(because it invokes libsvtav1 as a library, where `-threads` IS valid). +But this happened *per file*, making every encode go through the slow +single-pass ffmpeg fallback path instead of chunk-parallel av1an. + +### The fix + +**Don't inject `--threads` into av1an's `--video-params` at all.** +Revert `params_fn` to its v4.0.0 signature `(crf, preset) -> str` with +no threads parameter. Thread capping now happens via: + +1. **av1an's `--workers` flag** (chunk-parallel count) — this is what + `_compute_intelligent_worker_count` actually controls. Fewer workers + = fewer concurrent SVT-AV1 processes = less thread pressure. +2. **`-threads` in the ffmpeg fallback path** — `_svtav1_ffmpeg_args` / + `_vp9_ffmpeg_args` / `_x265_ffmpeg_args` already accept `-threads`, + passed to libsvtav1/libvpx/libx265 as library options (where it + works). + +The intelligent worker-count logic from v4.1.0 is **kept** — it still +caps `--workers` to `physical_cores - 1` and reserves 1 logical thread +for OS/UI. But the per-chunk thread cap that broke SVT-AV1 is gone. + +### What v4.1.2 keeps from v4.1.0/v4.1.1 + +- **Intelligent `--workers` count** — `_compute_intelligent_worker_count` + still caps chunk-parallel workers based on CPU topology. +- **Live progress tail** (v4.1.1) — av1an's stdout/stderr now emits to + the GUI log as it arrives, with `\r` progress bar handling. +- **30-second heartbeat** (v4.1.1) — `... still encoding (Xs elapsed)` + so you always know the encode is alive. +- **`--max-workers` / `--threads-per-worker` CLI flags** — still wired + through `env.av1an_flags`. `--max-workers` controls av1an's + `--workers`. `--threads-per-worker` is currently a no-op in the + av1an path (kept for future use if/when SVT-AV1's `--lp` flag is + wired in correctly). + +### What the av1an command looks like now + +``` +/usr/bin/av1an -i input.mkv --workers 4 --chunk-method select \ + --encoder svt-av1 \ + --video-params --preset 6 --crf 32 --keyint 240 \ + --audio-params -c:a libopus -b:a 64k \ + --concat mkvmerge -o output.mkv +``` + +No `--threads 6` in `--video-params` — SvtAv1EncApp accepts this cleanly. + +--- + +# OpenTranscode v4.1.1 — Production Release + +**v4.1.1 adds live progress tail + heartbeat** so you can see av1an is +working during long encodes. Also bumps threads-per-worker from 4 to 6 +for better SVT-AV1 per-chunk throughput. + +*(Note: the threads-per-worker bump in v4.1.1 was reverted in v4.1.2 — +see above.)* + +## The v4.1.1 fix (in detail) + +### The bug + +v4.1.0 capped threads per encoder instance at 4 to prevent the +thread-oversubscription hard-lock. That worked (no more hard locks), +but it made each chunk ~7x slower than v4.0.0's "grab all 28 threads" +behavior. The result: file 1 took 10+ minutes, and the user saw +**nothing** in the GUI log the entire time. + +The "nothing" was the real killer. The drainer threads in +`_run_with_stop_check` read av1an's stdout/stderr into StringIO +buffers but **only emitted them to the GUI log on process exit**. So +during a 10-minute encode, the user stared at: + +``` +[1/46] Encoding: video1.mp4 + Source: 1920x1080 -> Output: 1920x1080 + Chunking: select (av1an default if no override) + CMD: av1an -i ... --workers 4 --chunk-method select ... +``` + +...and nothing else for 10 minutes. Looked identical to a wedged +process. User assumed it was "borked" and killed it. + +### The fix (three parts) + +1. **Live tail** — the drainer now emits each line of av1an's + stdout/stderr to the GUI log **as it arrives**, prefixed with `│ ` + to distinguish from orchestrator messages. Handles both `\n` (log + lines like "scenecut: found 8 scene(s)") and `\r` (progress bar + updates like "Encoding 45%") as line boundaries, so av1an's progress + bar renders correctly in real-time. + +2. **30-second heartbeat** — the poll loop emits + `... still encoding (Xs elapsed)` every 30 seconds, so even if + av1an isn't producing line-delimited output (e.g. during a long + SVT-AV1 encode that only updates a `\r` progress bar), the user + knows the process is alive. + +3. **`IDEAL_THREADS_PER_WORKER` bumped from 4 to 6** — SVT-AV1 with + only 4 threads was too slow per-chunk. With 6 threads, each chunk + gets ~50% better throughput while staying under the logical-thread + budget. On a 28-thread Xeon, this changes the split from 6×4=24 + to 4×6=24 (same total, better per-chunk latency — the first chunk + completes sooner, so the user sees progress faster). + +### What the log looks like now + +``` +[1/46] Encoding: video1.mp4 + Source: 1920x1080 -> Output: 1920x1080 + Chunking: select (av1an default if no override) + CMD: av1an -i ... --workers 4 --chunk-method select ... + │ INFO encode_file: Input: 1920x1080 @ 29.763 fps, YUVJ420P, SDR + │ INFO encode_file: scenecut: found 8 scene(s) + │ DEBUG encode_file: Segmenting video + │ DEBUG encode_file: Segment done + │ INFO encode_chunk: Encoding chunk 1 + ... still encoding (30s elapsed) + │ INFO encode_chunk: Encoding chunk 2 + ... still encoding (60s elapsed) + │ SUMMARY ------------------------------------------ + │ Average Speed: 4.231 fps + SUCCESS: video1.mp4 (245.3MB -> 28.7MB, 12%) +``` + +### Worker-count math, updated for v4.1.1 + +| Machine | budget | workers | threads | active | reserved | +|----------------------------|--------|---------|---------|--------|----------| +| 4-core / 8-thread laptop | 7 | 1 | 7 | 7 | 1 | +| 8-core / 16-thread desktop | 15 | 2 | 7 | 14 | 1 | +| **14-core / 28-thread Xeon** | 27 | **4** | **6** | **24** | **4** | +| 32-core / 64-thread EPYC | 63 | 10 | 6 | 60 | 4 | +| 1-core / 2-thread VM | 1 | 1 | 1 | 1 | 1 | + +--- + +# OpenTranscode v4.1.0 — Production Release + +**v4.1.0 adds intelligent chunking** to prevent the thread-oversubscription +hard-lock that v4.0.0 hit on high-core-count machines. + +## The v4.1.0 fix (in detail) + +### The bug + +v4.0.0 introduced the `--chunk-method select` auto-override for phone- +recorded MP4s with sparse keyframes (see the v4.0.0 section below for +that fix). But `select` mode keeps the encode pipeline tighter than +the previous `hybrid` default — chunks warm up faster, more encoder +instances hit full tilt at the same instant. + +Meanwhile, `EncoderWorker.run()` was still computing +`worker_count = max(1, physical_cores - 1)` and passing no per-chunk +thread cap to the encoder. SVT-AV1's default `--threads 0` means "use +all logical cores," so each chunk-parallel worker spawned an +SvtAv1EncApp process that grabbed every logical thread. + +On a 28-thread Xeon (14 physical cores) with 13 chunk-parallel workers, +the math was: `13 × 28 = ~364 active threads on 28 logical CPUs`. The +kernel scheduler drowned, I/O wait escalated, and the box hard-locked +even though no single process was at fault. The 1-second STOP-button +poll in `_run_with_stop_check` couldn't get scheduled, so even clicking +STOP didn't recover it. + +### The fix (three parts) + +1. **`_compute_intelligent_worker_count()`** in `EncoderWorker` now + computes `(worker_count, threads_per_worker)` such that + `worker_count * threads_per_worker <= logical_threads - 1` (one + logical thread reserved for OS / UI / av1an orchestrator). The + budget is split using an ideal `4 threads per worker` — the empirical + sweet spot for SVT-AV1, x265, and vpxenc. Beyond ~6 threads per + encoder instance you hit memory-bandwidth contention and diminishing + returns. + +2. **The resolved `threads_per_worker` is passed to `params_fn`** so each + `_av1_params` / `_vp9_params` / `_x265_params` appends + `--threads N` to the encoder's `--video-params` string. Every per- + chunk encoder instance (SvtAv1EncApp / vpxenc / x265) now respects + its share of the thread budget instead of grabbing all cores. + +3. **Two new CLI flags** let the user override the auto math when + needed: + + ```bash + opentranscode --max-workers 4 # cap chunk-parallel worker count + opentranscode --threads-per-worker 6 # per-encoder thread cap + opentranscode --max-workers 4 --threads-per-worker 6 # full override + ``` + + Both are also visible in `--dry-run` and the GUI env-probe banner. + +### Worker-count math, by machine + +| Machine | budget | workers | threads | active | reserved | +|----------------------------|--------|---------|---------|--------|----------| +| 4-core / 8-thread laptop | 7 | 1 | 7 | 7 | 1 | +| 8-core / 16-thread desktop | 15 | 3 | 5 | 15 | 1 | +| **14-core / 28-thread Xeon** | 27 | **6** | **4** | **24** | **4** | +| 32-core / 64-thread EPYC | 63 | 15 | 4 | 60 | 4 | +| 1-core / 2-thread VM | 1 | 1 | 1 | 1 | 1 | + +The Xeon row is the user's box. v4.0.0 hit 13 × 28 = 364 threads → +hard lock. v4.1.0 hits 6 × 4 = 24 threads with 4 reserved for OS/UI. + +### Also new in v4.1.0 + +- `--dry-run` now prints the computed worker math so you can verify + the thread budget before launching a real encode. +- The GUI env-probe banner shows the same math on startup. +- `EncoderWorker.__init__` reads `env.av1an_flags["max_workers"]` and + `["threads_per_worker"]` as fallback when the explicit constructor + args aren't supplied — so the CLI flags reach the GUI-spawned + worker without `ui_window.py` code changes. + +### Backwards compatibility + +- `params_fn` accepts an optional third arg `threads=0`.

Hybrid does: + +1. `ffmpeg -c copy -f segment` to split the source at scene boundaries +2. Re-decode each segment to y4m via a second ffmpeg invocation +3. Pipe the y4m to the encoder (SvtAv1EncApp / vpxenc / x265) + +Phone-recorded MP4s (the `20190707_112725.11b774bacde3.mp4` files in +the production log) only have I-frames every 5–10 seconds. Scene +boundaries detected by av1an's `av_scenechange` rarely align with those +sparse keyframes. The segment muxer can only split on keyframes, so the +segment for scene N actually starts somewhere inside scene N-1's GOP. + +The result: the decoder has no I-frame reference → errors with +`[h264 @ 0x...] error while decoding MB 35 25` → the y4m pipe breaks → +the encoder reads EOF mid-frame → `Failed to read y4m frame delimiter. +Read broken. EOF: 1` → every chunk fails after 3 retries → no chunks +to concat → **no output file**. + +The previous ffmpeg fallback rescued the file, but it was slow (single-pass, +no chunk-parallel) and the diagnostic was misleading ("concat failure" +when it was actually a chunk-extraction failure). + +### The fix (three parts) + +1. **`_encode_one` now accepts a `chunk_method` parameter**. When av1an + fails with the y4m break pattern, it recursively retries with + `--chunk-method select`. Select uses VapourSynth's `select()` filter + to extract frames one-by-one — slower than Hybrid but reliable for + any file VapourSynth can open. This is faster than the ffmpeg + fallback (chunk-parallel still works) and produces identical-quality + output (same encoder, same params). + +2. **The working chunk_method is cached** in + `env.av1an_flags["chunk_method_override"]` so subsequent files skip + the wasted first attempt. + +3. **`env_probe` now probes for VapourSynth source plugins** via + `_probe_vs_source_plugins()`. When NONE are found, it pre-sets + `chunk_method_override = "select"` to avoid the wasted first attempt + entirely. The probe checks `~/.local/lib/vapoursynth/`, + `/usr/lib/vapoursynth/`, `/usr/local/lib/vapoursynth/`, and the + Debian multiarch path. + +### Also fixed + +The "SUMMARY block + non-zero exit" diagnostic previously misdiagnosed +y4m break failures as "concat failure" (because SVT-AV1 prints a +SUMMARY block per-chunk before the pipe breaks). The check is now +guarded by `"Failed to read y4m frame delimiter" not in stderr_full` so +it only fires for true concat failures. + +### New CLI flag + +```bash +opentranscode --chunk-method {auto,select,hybrid,segment,ffms2,lsmash,bestsource,dgdecnv} +``` + +Lets the user force a specific chunk method.
