Carl Eugen Hoyos	7b4e1466d4	Exit ffmpeg if swr_convert() fails.	13 years ago
Reimar Döffinger	6a3f1726af	Add missing av_free_packet. Fixes memory leak when encoding at least with mpegvideo using the new encode2 function. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	f3bd226de6	ffmpeg: Fix setting flags for codec copy. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	60991ad6ae	ffmpeg: Fix image allocation. This probably fixes some of the use of uninitialized issues valgrind shows in fate. It might also fix other issues. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	5d12b83ff1	ffmpeg.c: implement -debug_ts option Mostly useful for debugging purposes.	13 years ago
Clément Bœsch	b986590810	ffmpeg: remove unneeded ost->picref check. If there ost->picref is NULL, it will likely crash anyway a few lines below by dereferencing it in order to access video attribute.	13 years ago
Clément Bœsch	c214e98634	ffmpeg: remove pointless avcodec_get_frame_defaults(). filtered_frame is overwritten just below anyway.	13 years ago
Clément Bœsch	73413e6bca	ffmpeg: raise ENOMEM on avfilter_graph_alloc() failure.	13 years ago
Reimar Döffinger	c15f3bd3db	Simplify: use local variable with same contents directly. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	85f25cfa19	ffmpeg: fix passlogfile with multiple libx264 streams. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	a3c4371f3c	ffmpeg: prefer NULL over 0 for av_log context pointer parameter.	13 years ago
Clément Bœsch	158bd596a6	ffmpeg: move quality parameter to do_video_out() scope. This make do_video_out() and do_audio_out() consistent. Also simplifies callers.	13 years ago
Clément Bœsch	63b5e99fab	ffmpeg: make use of ret error out in transcode_video().	13 years ago
Clément Bœsch	086fc4d765	ffmpeg: move filtered_frame to the CONFIG_AVFILTER scope. This simplifies a bit the #ifdefery.	13 years ago
Clément Bœsch	9303b794b8	ffmpeg: move do_video_stats() above do_video_out(). This avoid a forward declaration.	13 years ago
Clément Bœsch	a78dd826ee	ffmpeg: move video stats code to do_video_out(). This will allow some simplifications in transcode_video().	13 years ago
Clément Bœsch	cf31060127	ffmpeg: move filtered_frame to video stream processing scope.	13 years ago
Clément Bœsch	aede21f1b6	ffmpeg: reindent after video frame polling simplification.	13 years ago
Clément Bœsch	e22c7b4e25	ffmpeg: simplify video frame polling. input_video_filter and output_video_filter can't be NULL at this point. If they are, the current code would likely crash anyway (since filtered_frame would be NULL and sent to do_video_out().	13 years ago
Clément Bœsch	4ab4b3db5a	ffmpeg: use exit_program() if configure_video_filters() fails.	13 years ago
Michael Niedermayer	29034e6503	ffmpeg: Add threshold to discard crazy/damaged timestamps. The added tests are limited to the case where timestamp discontinuities are not allowed. The default is 30 hours which is arbitrarily picked and quite conservative. This prevents a out of memory condition due to duplicating a frame millions of times. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Anton Khirnov	67c63176ad	ffmpeg: remove setting fb->pts. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	d97fa416d6	ffmpeg: reduce overloading for InputStream.pts. It currently has different meanings at different times (dts of the last read packet/pts of the last decoded frame). Reduce obfuscation by storing pts of the decoded frame in the frame itself. Conflicts: ffmpeg.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	6028bd0dc6	ffmpeg: move next_dts/pts update out of transcode_video() this makes it placed similar to qatar Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	4eea0cfc22	ffmpeg: use ist->dts instead of passing an argument into transcode_video(). This makes the code more similar to qatar And fixes decoding of the last frame of fate/vc1-ism Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	f72eaf69ab	ffmpeg: Init dts variables in output_packet() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Reimar Döffinger	05741d70c7	Fallback to input timestamps for non-delay encoders. Causes FFmpeg to pass through the correct pts values, instead of clobbering all to AV_NOPTS_VALUE (the av_init_packet default) to then make up new ones based on only fps when muxing. Included are also the related FATE ref changes, which all some reasonable on quick investigation. Also set all H.264 references to us -vsync drop to reduce the diff for the ref files. Otherwise almost all H.264 references need to change, mostly due to now starting with negative pts values. About 20 additional H.264 conformance tests needed -vsync drop anyway because they create pts values that are out of order and thus not possible to mux otherwise. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	47a5274104	Add -vsync drop. This allows to work around any non-monotonic time-stamp errors by just discarding all time stamps. This will be necessary to allow H.264 conformance tests to pass after fixing time stamps to be passed through rawenc. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
