Paul B Mahol	e53260c1f4	avfilter/af_silenceremove: add ptp detector	2 years ago
Anton Khirnov	163e3a299e	fftools/sync_queue: make sure non-limiting streams are not used as queue head A non-limiting stream could mistakenly end up being the queue head, which would then produce incorrect synchronization, seen e.g. in fate-matroska-flac-extradata-update for certain number of frame threads (e.g. 5).

Anton Khirnov	6ee57fd2b6	fftools/ffmpeg_demux: only print demuxing stats if demuxing actually started If the transcoding process never got to reading any packets from this input then printing stats is just pointless noise.	2 years ago

Anton Khirnov	ec75b79fe1	fftools/ffmpeg: fail earlier on text/bitmap subtitles mismatch Checking whether the user requested an unsupported conversion between text and bitmap subtitles can be done immediately when creating the output stream.	2 years ago
Anton Khirnov	2b3905254e	fftools/ffmpeg_enc: use AVFrame.hw_frames_ctx for encoder hw setup It should be the same as the one that can be extracted from the filter and does not require access to outside data.	2 years ago
Anton Khirnov	f15b206286	fftools/ffmpeg_hw: move hw_device_setup_for_encode() to ffmpeg_enc This function is entangled with encoder setup, so it is more encoding code rather than ffmpeg_hw code. This will allow making more encoder state private in the future.	2 years ago
Anton Khirnov	760a9bd306	fftools/ffmpeg_hw: move hw_device_setup_for_decode() to ffmpeg_dec This function is entangled with decoder setup, so it is more decoding code rather than ffmpeg_hw code. This will allow making more decoder state private in the future.	2 years ago
Paul B Mahol	e8e4863325	avfilter/af_silenceremove: fix the any/all confusion and change default 'any' stop mode is now correctly implemented for end trimming and is of limited usage. Extend examples and other documentation of this filter.	2 years ago
Paul B Mahol	8d662adcc9	avfilter/af_silenceremove: speed-up filtering once start-trim is over No point to call filter_start on samples that will pass them unchanged once initial trimming stopped.	2 years ago

Paul B Mahol	7927a96e2b	avfilter/af_silenceremove: add commands support	2 years ago
James Almer	e86e2d5921	fftools/ffmpeg_dec: abort if avcodec_send_packet() returns EAGAIN As the comment in the code mentions, EAGAIN is not an expected value here because we call avcodec_receive_frame() until all frames have been returned. avcodec_send_packet() returning EAGAIN means a packet is still buffered, which hints that the underlying decoder is buggy and not fetching packets as it should. An example of this behavior was in the libdav1d wrapper before `f209614290`, where feeding it split frames (or individual OBUs) would result in the CLI eventually printing the confusing "Error submitting packet to decoder: Resource temporarily unavailable" error message, and just keep going until EOF without returning new frames.

Paul B Mahol	3235de4883	avfilter/af_silenceremove: switch to activate Do full rewrite, new code is much faster for typical filter usages. Also previous code was hard to follow and basically very-hard to maintain.	2 years ago

Niklas Haas	0bce5590c3	lavfi/vf_libplacebo: fix crop expr PTS calculation mix->timestamps is expressed relative to the source timebase, which is possibly a different timescale from `base_pts`. We can't mix-and-match here. The only reason this worked in my previous testing was because I was testing on a source file which had an exactly matching timebase.
