 | `ffmpeg.qsv-decode-encode-split` | QSV decode is decoupled from QSV encode via a single `FFmpegProfile.QsvPreferNativeDecoder` bool (default ON, Linux-only), so a QSV encode profile can decode with the more tolerant native VA-API decoder instead of the QSV decoder, mirroring Jellyfin's hybrid decode/encode toggle instead of a general decode-family enum. | 2026-07-20 | [link](records/ffmpeg/qsv-decode-encode-split.md) |
 | `ffmpeg.qsv-extra-hw-frames-floor` | a QSV upload never emits `extra_hw_frames` below `FFmpegState.MinimumQsvExtraHardwareFrames` (64); a stored `0` or negative value is treated as "no pool configured" rather than honored literally, because with no headroom any unthrottled read exhausts the pool and the transcode writes nothing at all. | 2026-07-21 | [link](records/ffmpeg/qsv-extra-hw-frames-floor.md) |
 | `ffmpeg.qsv-hdr-tonemap-opencl` | the QSV pipeline never emits `vpp_qsv=tonemap=1`, which is a SILENT no-op on pre-Gen11 Intel graphics; HDR is tonemapped on the GPU via `hwupload=derive_device=vaapi` → `scale_vaapi` → `hwmap=derive_device=opencl` → `tonemap_opencl` when a VA-API device exists, the frames are still in software, and `tonemap_opencl` is available, and by the software `TonemapFilter` otherwise. The scale runs BEFORE the tonemap, and any hardware filter on the path forces the output to be re-tagged bt709. | 2026-07-26 | [link](records/ffmpeg/qsv-hdr-tonemap-opencl.md) |
-| `ffmpeg.readrate-catchup-sparse-streams` | a realtime video/audio input also gets `-readrate_catchup` (6.0) when the binary supports it — but NOT a still-image input (mirroring #350's exclusion) and NOT a concat input, which keep at most bare `-readrate` (a still image's video input takes none at all). Reason: `-readrate` paces the whole input off its furthest-behind stream, so a sparse stream sharing that input (an embedded PGS/DVD bitmap subtitle feeding the overlay) otherwise pins output at ~0.53x realtime. Catchup is a ceiling that applies only WHILE an input is behind, never a target, so it does not let a caught-up input race ahead. | 2026-08-04 | [link](records/ffmpeg/readrate-catchup-sparse-streams.md) |

 | `ffmpeg.remote-image-fetcher-bounded` | remote graphics-engine images are fetched through `IRemoteImageFetcher` with a pooled `HttpClientFactory` client, a body-covering deadline, a wire-transfer size cap, and a decoder-enforced `DecoderOptions.MaxFrames` bound re-verified post-decode — never cached, re-fetched per element init. | 2026-07-20 | [link](records/ffmpeg/remote-image-fetcher-bounded.md) |
 | `ffmpeg.watermark-resolution-unified` | Every watermark `WatermarkSelector` resolves goes through one shared `ResolveWatermark` — the playout-item, channel and global precedence levels AND the deco path, for all three `ChannelWatermarkImageSource` values. An unresolvable watermark (missing file, un-migrated external URL, or no logo artwork) resolves to no on-screen bug plus a warning, never a dead path or a URL handed downstream; the one deliberate exception is a playout-item `Custom` with a blank image, which still falls THROUGH to channel/global. The generated-initials fallback is therefore off everywhere, including the deco path where it demonstrably rendered. Watermarks built OUTSIDE the selector (the song-progress overlay, #653) are not covered and remain unchecked. | 2026-07-26 | [link](records/ffmpeg/watermark-resolution-unified.md) |
 | `ffmpeg.work-ahead-slot-atomic` | `workAheadSegmenterLimit` is enforced by a single compare-exchange claim on a shared `WorkAheadSlots` pool taken by the *caller* of `Transcode`, which then passes ownership in and gets the release in `Transcode`'s `finally` — never a `Volatile.Read` compare in one place and an `Interlocked.Increment` in another. | 2026-07-21 | [link](records/ffmpeg/work-ahead-slot-atomic.md) |
