Michael Niedermayer	4204364678	ffmpeg: switch duration calculation code from avg to r frame_rate. This heuristic is less likely to overshoot and cause encoder failure. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a37a281778	ffmpeg: pass bitexact flag to vsrc_buffer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	9aeacc9546	ffmpeg: dont disable dr1 when changing dimensions are encountered in codec_get_buffer(). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	e5c3b51cd1	ffmpeg: disable dr1 when frame sizes change. dr1 seems to work fine with frame size changes but many filters cant handle it yet. Simply disabling it forces the alternative non dr1 code path which has been tested more completely and is known to handle frame size changes in a wider varity of cases.

Stefano Sabatini	99bb88c588	doc/ffmpeg: update and extend documentation for -copytb Address trac ticket #1120.	13 years ago
Michael Niedermayer	a0820eaa8a	ffmpeg: fix handling or empty audio packets Fixes Ticket1131 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	b62b9df798	ffmpeg: more verbose error messages in case of audio encoding failure. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	21d650cb69	ffmpeg: more expressive sample rate automatic selection. Output now lists the available sample rates with commands like ffmpeg -f lavfi -i aevalsrc=0 -ar 20000 -y /tmp/out.mp3	13 years ago
Julien Ramseier	e479013ae4	Fix SVCD scan_offset option Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	f4c380a5e6	ffmpeg: drop struct from SwrContext. Its a typdef now and doesnt need the struct anymore. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1664edb998	ffmpeg: check samplerate from decoder. Fixes FPE Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	ffa28da180	Support dropping audio dts/pts via -async -1. Allows working around issue #605. Note: as a side effect this fixes that -vsync drop as far as I could tell would not drop pts/dts values when duplicating frames or when flushing encoder delay. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	4c1da0d11e	ffmpeg: allow selective and complete disabling of map_metadata. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7230116000	ffmpeg: Fix planar audio input. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	ad53c7f9ec	lavf: Add system to seperate relative timestamps from absolute ones. With this we can always know if a timestamp is based on added durations from an unknown origin or if it is based on a correct timestamp (and possibly added durations) This should fix some bugs where this distinction was mixed up. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	78306c51ef	ffmpeg: show fps more accurately when it is small.	13 years ago
Rick van der Zwet	d33a091cb3	ffm options should also set discard automatically. commit `13f6917ca9` handles discards automatically, but the ffm discard options are not fully parsed. Causing the input streams not to be used, so no stream towards the ffserver after the initial probing. Signed-off-by: Rick van der Zwet <info@rickvanderzwet.nl> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	c250063523	get_buffers: Check that pix_fmt is not NONE. This is somewhat redundant as no decoder should call get_buffer() with such argument. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	ddd86a2924	ffmpeg: Fix division by 0 due to invalid timebase Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
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	67700e877d	ffmpeg: update dts variables in transcode_audio() 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
