Anton Khirnov	6bbea932ca	fftools/ffmpeg: set AVFrame.time_base for decoded frames Makes it easier to keep track of the timebase the frames are in.	2 years ago
Anton Khirnov	b6e7d64394	fftools/ffmpeg: stop using packet pts for decoded audio frame pts If input packets have timestamps, they will be propagated to output frames by the decoder, so at best this block does not do anything. There can also be an arbitrary amount of delay between packets sent to the decoder and decoded frames (e.g. due to decoder's intrinsic delay or frame threading), so deriving any timestamps from packet properties is wrong.	2 years ago
Anton Khirnov	5b3aeab1bd	fftools/ffmpeg_filter: use correct timebase for filter EOF timestamp It does not need to be equal to demuxer timebase.	2 years ago
Anton Khirnov	0aada80e73	fftools/ffmpeg_filter: keep track of filtergraph input timebase Will be useful in following commits.	2 years ago
Anton Khirnov	04f0c40c74	fftools/ffmpeg_filter: add InputFilter private data Move InputFilter.frame_queue to it, which is not accessed outside of ffmpeg_filter.	2 years ago

Anton Khirnov	87ced7aee0	fftools/ffmpeg_filter: make graph_desc private It is not used outside of ffmpeg_filter.	2 years ago
Anton Khirnov	09dd9c5f41	fftools/ffmpeg_filter: add filtergraph private data Start by moving OutputStream.filtered_frame to it, which really belongs to the filtergraph rather than the output stream.	2 years ago
Anton Khirnov	aee5b774bf	fftools/ffmpeg_filter: make ifilter_parameters_from_frame() static It is no longer used outside of this file.	2 years ago
Anton Khirnov	38c937e8c4	fftools/ffmpeg: drop undocumented runtime debug-setting This feature is of highly questionable usefulness and - as the comment in the code says - is not actually supported by the API.	2 years ago
Anton Khirnov	7e3eb24123	fftools/ffmpeg: move OutputStream.packets_encoded to Encoder It is no longer used outside of ffmpeg_enc.	2 years ago
Anton Khirnov	6e487a50a1	fftools/ffmpeg: drop OutputStream.error Only the first component is used in update_video_stats(), so make it a stack variable in that function.	2 years ago
Anton Khirnov	52b632b65b	fftools/ffmpeg: drop OutputStream.pict_type It is no longer used outside of update_video_stats(), so make it a stack variable in that function.	2 years ago
Anton Khirnov	f4a60b8ddc	fftools/ffmpeg: reduce access to OutputStream.enc_ctx It will be made private to Encoder in the future.	2 years ago
Anton Khirnov	5a04aae821	fftools/ffmpeg: deprecate -adrift_threshold This option has had no effect since -async was removed in `3d86a13b47`	2 years ago
Anton Khirnov	0ed1eeb744	lavf/dv: use a more granular timebase for audio One that is fine enough to represent all DV audio sample rates. Audio packet durations are now sample-accurate. This largely undoes commit `76fbb0052d`. To avoid breaking the issue fixed by that commit, resync audio timestamps against video if they get more than one frame apart. The sample from issue #8762 still works correctly after this commit. Slightly changes the results of the lavf-dv seektest, due to the audio timebase being more granular.	2 years ago
Anton Khirnov	aae5ba31ca	lavf/dv: shorten code by using a local variable	2 years ago
Anton Khirnov	c7a852b638	lavf/dv: do not set video timebase more than once Current code will call avpriv_set_pts_info() for each video frame, possibly setting a different timebase if the stream framerate changes. This violates API conventions, as the timebase is supposed to stay constant after stream creation. Change the demuxer to set a single timebase that is fine enough to handle all supported DV framerates. The seek tests change slightly because the new timebase is more granular.	2 years ago
