Changes:
ffmpegfs (2.50-1) unstable; urgency=medium
.
* Bugfix: Fixed audio/video synchronization issues during transcoding.
* Bugfix: Fixed HLS playback stopping unexpectedly, especially near the final
segment.
* Refactored FFmpeg resource handling to use RAII wrappers for AVPacket,
AVFormatContext, AVAudioFifo, AVDictionary, SwrContext, and SwsContext.
* Removed deprecated av_init_packet() usage and switched packet handling to
allocation-based AVPacket lifetime management.
* Improved cleanup of FFmpeg input/output contexts, including custom
AVIOContext handling and error paths during context allocation.
* Improved audio FIFO, resampler, scaler, and dictionary lifetime management
to reduce manual cleanup code and avoid leaks on error paths.
* Cleaned up transcoder shutdown paths by centralizing FFmpeg resource cleanup
in dedicated wrapper classes.
* Bugfix: Fixed retained FFmpeg deinterlace filter graphs when the output
pipeline is rebuilt, especially after HLS seeks. Old filter graphs are now
released before reinitialisation and when closing the current output,
preventing stale filter pointers and retained filter buffers.
* Bugfix: Fixed HLS playback stopping unexpectedly, especially near the last
HLS segment.
* Bugfix: Improved HLS segment finalisation and state cleanup between segment
transitions.
* Bugfix: Improved packet/frame lifetime handling to avoid stale state during
HLS playback.
* Added a `make help` target to list the available build, test, installation,
documentation and maintenance targets.
* Added `./configure --enable-perftools` to build ffmpegfs with Google
Perftools heap profiling support.
* Bugfix: Fixed HLS playback for 10-bit UHD/HDR sources by converting H.264
HLS output to yuv420p/8-bit. This avoids unsupported H.264 High10 streams
in browser-based players such as hls.js.
* Added elapsed-time reporting to successful transcode completion messages,
showing the total transcoding time in milliseconds.
* Bugfix: Fixed a race condition in transcoder thread start-up which could
allow the same cache entry to be transcoded more than once concurrently.
* Consolidated transcoder completion logging so each worker now emits one
clear final status message, including elapsed runtime for successful
transcodes.
* Bugfix: Fixed HLS cache recovery so stale segment metadata no longer leaves
playback waiting indefinitely when the corresponding cache file is missing,
empty, or otherwise unusable.
* Improved HLS segment recovery by explicitly restarting the transcoder when
a segment is marked as available but its cache file is missing, empty, or
otherwise unusable.
* Bugfix: Fixed HLS segment availability checks so an incomplete cache entry
no longer makes segments appear available if those segments were never
actually produced.
* Added additional safeguards for stale decoder state to avoid leaving cache
entries permanently marked as decoding when no active worker is available
to repair them.
* Bugfix: Ignored HLS seek requests that are too close to the beginning of
a stream so transcoding starts at segment 1 instead of creating an
avoidable partial cache set.
* Added an HLS cache regression test that pre-populates the cache, re-reads
all generated segments, and verifies that cached segment output remains
stable across repeated reads.
* Bugfix: Fixed HLS cache test log naming so wrapper scripts which already
contain the "_hls" suffix no longer generate duplicate "_hls_hls" builtin
log files.
* Bugfix: Fixed distclean/distcheck failures caused by incorrectly named HLS
test log files being left behind in the test build directory.
* Refactored transcoder stream and output initialisation into smaller helper
functions, keeping high-level setup flow easier to follow.
* Improved AVCodecContext ownership handling during stream, output, and
frame-set setup so partially failed initialisation paths no longer leak
codec contexts.
* Hardened output/cache setup with additional validation and null checks to
avoid partially initialised stream state and clearer error handling on
invalid setup conditions.
* Improved duration metadata handling for stream-copy and album-art output so
invalid or missing input timing information is no longer used.
* Improved test cleanup by using explicit ffmpegfs-owned temporary directory
names and guarded removal logic, avoiding stale anonymous /tmp directories
after interrupted or parallel test runs.
* Improved deinterlacing quality by replacing yadif with bwdif while keeping
one output frame per input frame. This improves playback smoothness for
interlaced sources without changing the output frame rate or requiring
changes to timestamp, FPS, or HLS segment timing logic.
