Michael Niedermayer	0478d5f9fe	ffmpeg: allow overriding framerate for stream copy Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	eae983f4ff	ffmpeg: fix fate breakage introduced by key=value buffersrc args. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	6fef82f22d	ffmpeg: with filter_complex, avoid random in<->out mapping. With complex filters, an output can come from any input, or several inputs, including inputs of a different type. Copying the codec parameters from the first input with the same type does not make any sense. This does not change anything for simple 1->1 filters, as source_index is set in that case.	13 years ago
Nicolas George	fbaa8fe6c6	ffmpeg: init icodec. With complex filter graphs, it can end up accessed without having been set.	13 years ago
Nicolas George	8362d734a3	ffmpeg: use the frame rate computed by lavfi. This frame rate is more reliable than the one copied from the input stream, so it is used in priority.	13 years ago
Nicolas George	5f281e94ba	ffmpeg: add frame rate to the buffersrc arguments. The arguments now use the key=value syntax.	13 years ago
Mike Scheutzow	1be7bfdd2b	ffmpeg.c: fix erroneous "Output file is empty" message. This message is printed whenever the RAWVIDEO codec is used, whether the output file contains any frames or not. Test command: ./ffmpeg -i infile.y4m outfile.y4m Signed-off-by: Mike Scheutzow <mjs973@optonline.net> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	25e87fc5f6	ffmpeg: move keyboard interaction in a function. It makes the transcode loop easier to read (30% less code) and the differences with avconv easier to spot.	13 years ago
Philip Langdale	92c065f93f	ffmpeg: Set duration on encoded subtitle packets. Currently, we don't set the duration on the packet of a newly encoded subtitle. This information may be required by the muxer. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	93147daf59	ffmpeg: avoid a confusing and easy to break if(). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	c8a11014b6	ffmpeg: use isatty() before messing with the terminal state This fixes terminal messup in case of crashes (like in make fate) Reviewed-by: François Revol <revol@free.fr> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	df03ae8dd8	ffmpeg: remove two unused variables.	13 years ago
Michael Niedermayer	02ff89a1cd	ffmpeg: disable audio volume insertion on the output side. This fixes -vol leading to 2 inserted volume filters Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	c790ae0265	ffmpeg: add missing return carriage in error message.	13 years ago
Clément Bœsch	6b35f1a2a6	timecode: move timecode muxer options to metadata. Some demuxers set a timecode in the format or streams metadata. The muxers now make use of this metadata instead of a duplicated private option. This makes possible transparent copy of the timecode when transmuxing and transcoding. -timecode option for MPEG1/2 codec is also renamed to -gop_timecode. The global ffmpeg -timecode option will set it anyway so no option change visible for the user.	13 years ago
Stefano Sabatini	f1add01d98	ffmpeg: be more verbose when printing an error in transcode() Helps debuggability.	13 years ago
Stefano Sabatini	6a9854e8f4	ffmpeg: specify more meaningful names for the lavfi buffer sources	13 years ago
Nicolas George	8b0e173529	ffmpeg: use filter time base as codec time base.	13 years ago
Nicolas George	48b5bcb3dd	ffmpeg: avoid NULL dereference with filters. icodec can be NULL if there is no input stream clearly associated with the output stream.	13 years ago
Michael Niedermayer	d43812e235	ffmpeg: move pan filter insertion up. This fixes one (disabled) fate test. Thanks-to: ubitux to pointing at the odd filter order and stereo/mono messup Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	23b365f1c4	ffmpeg: fix memleak Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	60de761657	ffmpeg: allow overriding input top field first Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	96fe99cb11	ffmpeg: disable autoinsertion for -async on the output side of the filtergraph. This fixes the issue that since the last merge -async caused 2 aresample filters to be inserted users that generate funny timestamps in a filtergraph should probably manually insert a aresample filter where they need it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	d187e7616e	ffmpeg: use %f instead of %lf in volume args format printf. %f refers to a double argument already.	13 years ago
Clément Bœsch	d8e075b1a0	ffmpeg: use AUTO_INSERT_FILTER() for -async option.	13 years ago
Matthieu Bouron	432fe9a38a	ffmpeg: fix a crash with complex filters when pix_fmt is not specified ffmpeg -i in.mxf -filter_complex "[0:0]fieldorder=tff" out.wav will fail with an error message instead of crashing. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	3c0013213e	ffmpeg: move audio timestamp roundup code. This fixes a regression which lead to non monotone timestamps at the end of a file. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	fc49f22c3b	ffmpeg: add support for audio filters. Some of the FATE changes are due to off-by-one different rounding being used (lrintf vs av_rescale_q). Some fate changes are due to 1 audio frame less being encoded (the new variant seems matching what qatar does and according to ffprobe its closer to the requested duration) the mapchan feature sadly is lost in this commit because it depends on resampling being done in ffmpeg.c which is now moved completely into the av filter layer -async is broken after this commit, this will be fixed in subsequent commits the new filter reconfiguration system is flawed and will drop a frame on each parameter change which is why the nelly moser checksums need updating.
