Nicolas George	299a56879d	ffmpeg: make reading packets from thread blocking. If a packet is not ready on the input selected by ffmpeg, it will read from another input instead. If that happens repeatedly, frames will accumulate somewhere later in the processing to ensure streams synchronization. It can happen in particular when reading from a slow medium or an expensive lavfi filter graph. Make reading from normal demuxers on non-streamed data and from the lavfi pseudo-device blocking to avoid that. Should fix trac ticket #3079.	11 years ago
Michael Niedermayer	3e70c7023e	ffmpeg: support setting the chroma intra matrix Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	740e6042a0	ffmpeg: change ost->finished to an enum Idea-by: ramiro Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	d7ebeba80c	ffmpeg: Do not fill gap before the first decodable frame on single stream input files unless the user explicitly requests it. Fixes different behavior to JM and probably several if not all reference decoders. We cannot just do this unconditionally as it would ruin AV sync in some use cases.

Stefano Sabatini	0f8bdfe3e8	ffmpeg: store value of -filter and -filter_script per-stream option in OutputStream struct Avoid the need for multiple potentially inconsistent access operations, slightly factorize code.	11 years ago
Michael Niedermayer	b6b9c150f0	ffmpeg: add max_error_rate to allow tuning the point decoding errors are considered a failure of the whole transcoding. Suggested-by: Daemon404 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	33ff943f70	ffmpeg: add -apad option which injects a apad filter only in the presence of video streams Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	de38e7c8c3	ffmpeg: use a rational for -aspect option.	12 years ago
Michael Niedermayer	4c1f61b1e8	ffmpeg: Correct inter stream timestamp discontinuities Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	cb2bd91413	ffmpeg: add the -canvas_size option. Allows, amongst other things, to override the size guessed by the sub2video hack. Note: the -s option could have more or less the same semantic, but it receives a special treatment by the options system.	12 years ago
Nicolas George	f9b34b8bf9	ffmpeg: port sub2video to AVFrame. And re-enable the FATE test.	12 years ago
Jean First	2d7044683f	ffmpeg_opt: add -to option to specify stop time Signed-off-by: Jean First <jeanfirst@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	e42028925b	ffmpeg: Force a first_pts of 0 for the first configuration of -async use This is very close to what the default does currently Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	ad899522ff	ffmpeg: use a AVDictionary instead of the context to move swr parameters around This avoids per parameter changes in ffmpeg at the cost of making access somewhat more annoying. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	43af18ef8b	ffmpeg: implement -force_key_frames expression evalution	12 years ago
Nicolas George	fccd8c21c4	ffmpeg: add -guess_layout_max option.	12 years ago
Nicolas George	0f236345fb	ffmpeg: sub2video: use start and end time. Until now, the end_display_time was ignored, making single packets subtitles (like dvdsub) stay indefinitely. start_display_time was also ignored, but is it almost always 0.	12 years ago
Michael Niedermayer	b5e0e327ce	ffmpeg: fix swr filter_type for auto inserted aresample filters Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a9d97e1b0a	ffmpeg: use av_rescale_delta() on the audio filter input Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	3e0b29ccd0	ffmpeg: Make video filter graph reinit user selectable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	65f7aee63b	ffmpeg: add option to control copying of frames prior to start. Normally we discard things prior to the intended start for stream copy this is not always possible, and its not done by default this option allows discarding to be enabled this is primarely usefull when transcoding a video and stream copying an audio stream.

Nicolas George	6d8b32633e	ffmpeg: use PTS from the AVSubtitle structure.	12 years ago
Nicolas George	0cad101ea1	ffmpeg: add an option to fix subtitles durations. With this option, transcoding DVB subtitles becomes possible.	13 years ago
