Anton Khirnov	0ad26cdf24	avconv: add support for audio in complex filtergraphs.	13 years ago
Anton Khirnov	01e98b1b00	avconv: fix behavior with -ss as an output option. Don't return from poll_filters() immediately, there may be other frames and/or other streams to handle. Fixes a memleak.	13 years ago
Anton Khirnov	6eeb9a0433	avconv: automatically insert asyncts when -async is used. Deprecate -async.	13 years ago
Anton Khirnov	369cb092ec	avconv: add support for audio filters. The FATE changes are all off-by-one due to different rounding being used (lrintf vs av_rescale_q).	13 years ago
Anton Khirnov	720c6b78d1	buffersrc: add av_buffersrc_write_frame(). It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts or pixel_aspect parameters. Those are read from AVFrame. Deprecate av_vsrc_buffer_add_frame().	13 years ago
Mans Rullgard	4f1500689d	avconv: use lrint() for rounding double timestamps Converting the double to float for lrintf() loses precision when the value is not exactly representable as a single-precision float. Apart from being inaccurate, this causes discrepancies in some configurations due to differences in rounding. Note that the changed timestamp in the vc1-ism test is a bogus, made-up value.

Anton Khirnov	a5117a2444	lavc: pad last audio frame with silence when needed.	13 years ago
Anton Khirnov	ac71230902	lavfi: add video buffer sink, and use it in avtools Also add the public interface libavfilter/buffersink.h. Based on a commit by Stefano Sabatini.	13 years ago
Anton Khirnov	dce415e7f1	avconv: remove stray useless comment.	13 years ago
Mans Rullgard	3527a73933	avutil: add av_parse_cpu_flags() function This moves the cpu flag parsing code from avconv to avutil so it can be accessed elsewhere. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	bcb82fe1f4	avconv: use libavresample	13 years ago
Anton Khirnov	8c4022aceb	avconv: fix a segfault on -c copy with -filter_complex.	13 years ago
Luca Barbato	1381081cdb	avconv: fix off by one check in complex_filter nb_input_files is already an invalid index.	13 years ago
Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	2994913d70	avconv: fix a segfault when default encoder for a format doesn't exist. Fail earlier and with a more descriptive error message.	13 years ago
Justin Ruggles	d8b06521a9	avconv: check for an incompatible changing channel layout The decoder can change the layout and channel count during decoding, but currently we only validate that the two are compatible when opening the codec. This checks for incompatibilities after each decoded frame.	13 years ago
Justin Ruggles	b1041f8048	avconv: only set the "channels" option when it exists for the specified input format This allows the user to specify an input channel layout without avconv aborting because the "channels" option was not found.	13 years ago
Anton Khirnov	9e8aae443b	avconv: flush decoders immediately after an EOF. Prevents extensive buffering when overlaying a single picture.	13 years ago
Anton Khirnov	89605e4aa0	avconv: send EOF to vsrc_buffer.	13 years ago
Anton Khirnov	3e901cbc75	avconv: reindent.	13 years ago
Anton Khirnov	3b266da3d3	avconv: add support for complex filtergraphs.	13 years ago
Anton Khirnov	560f7774a4	avconv: make filtergraphs global. This is the first step towards supporting complex filtergraphs with more than one input and/or output.	13 years ago
Anton Khirnov	836ce90566	avconv: move filtered_frame from InputStream to OutputStream. It more properly belongs to output, not input.	13 years ago
Anton Khirnov	6c9eac1998	avconv: don't set output width/height directly from input value. Always take it from lavfi. This way we don't need a clearly defined corresponding input stream.	13 years ago
Anton Khirnov	e77c86629f	avconv: move resample_{width,height,pix_fmt} to InputStream. This is a more proper place for them, since they store parameters of the input, not output, stream.	13 years ago
Anton Khirnov	9dced85426	avconv: remove a useless variable from OutputStream.	13 years ago
Anton Khirnov	b7327887ea	avconv: get output pixel format from lavfi. This way we don't require a clearly defined corresponding input stream. The result for the xwd test changes because rgb24 is now chosen instead of bgra.	13 years ago
Anton Khirnov	2e21526790	avconv: change {input,output}_{streams,files} into arrays of pointers. Right now, they are arrays of structs, reallocated when new streams/files are added. This makes storing pointers to those structs harder than necessary.	13 years ago
Anton Khirnov	ea9367e921	avconv: don't pass input/output streams to some functions. They are globals, no point in pretending they are not.	13 years ago
Stefano Sabatini	91d3cbe0fd	avfiltergraph: make the AVFilterInOut alloc/free API public This is required for letting applications to create and destroy AVFilterInOut structs in a convenient way. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Justin Ruggles	d3c59d5003	avconv: use default channel layouts when they are unknown If either input or output layout is known and the channel counts match, use the known layout for both. Otherwise choose the default layout based on av_get_default_channel_layout(). Changed some FATE references due to some WAVE files now having a non-zero channel mask.	13 years ago
Justin Ruggles	95a8dac57b	avconv: parse channel layout string This allows the user to use channel layout names instead of having to use the channel mask values.	13 years ago
Justin Ruggles	b073819bc9	avconv: allow '-async -1' to disable timestamp sync for audio encoding This will allow a workaround for cases where input timestamps are invalid or when decoder delay of 1 packet or more confuses avconv into using the wrong timestamps as a sync reference.	13 years ago
Justin Ruggles	679a973e97	avconv: use default alignment for audio buffer	13 years ago
Anton Khirnov	b6c4518a87	avconv: remove OutputStream.picref. It's only used inside transcode_video() and there's no point in preserving it between subsequent calls. So use a local variable instead.	13 years ago
Anton Khirnov	695ec04e6a	avconv: only set SAR once on the decoded frame. No point in repeating the assignment for each output stream.	13 years ago
Anton Khirnov	d4936548f4	avconv: remove an unused function parameter.	13 years ago
Anton Khirnov	4648fe6324	avconv: remove now pointless variables.	13 years ago
Anton Khirnov	e06d2dfcde	avconv: drop support for building without libavfilter. Since the mandatory memcpy in vsrc_buffer has been eliminated, there shouldn't be any significant reason to build without lavfi anymore. This will make upcoming support for complex filtergraphs easier to do.	13 years ago
Ronald S. Bultje	bc1ef85520	lavc/avconv: support changing frame sizes in codecs with frame mt. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Justin Ruggles	4094fc9971	avconv: fix the resampling safety factors for output audio buffer allocation This matches the output size required for audio_resample()	13 years ago
Justin Ruggles	9869e963a6	avconv: move audio output buffer allocation to a separate function Allows for removing a goto and makes the code easier to follow.	13 years ago
Justin Ruggles	f3ab3e1aee	avconv: make the async buffer global and free it in exit_program()	13 years ago
Justin Ruggles	c9594fe0fb	avconv: free packet in write_frame() when discarding due to frame number limit Fixes a memleak when using the -frames option with audio.	13 years ago
Justin Ruggles	9b9fc9ba32	avconv: pass input stream timestamps to audio encoders 5 FATE test references updated due to using demuxer-generated timestamps that are either not sample-accurate or are slightly off in the input file.	13 years ago
Anton Khirnov	251422982b	avconv: remove pointless checks. OutputStream.picref is guaranteed to be non-NULL if get_filtered_video_frame() succeeds.	13 years ago
Anton Khirnov	ce326c1130	avconv: check for get_filtered_frame() failure.	13 years ago
Anton Khirnov	2636e691ce	avconv: remove a pointless check. output_video_filter is always guaranteed to be set and is in fact dereferenced right above the check.	13 years ago
Anton Khirnov	64334ddbbc	avconv: reindent CC: libav-stable@libav.org	13 years ago
