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
Anton Khirnov	6e8be949f1	avconv: link '-passlogfile' option to libx264 'stats' AVOption. Fixes bug 204. CC: libav-stable@libav.org	13 years ago
Anton Khirnov	4138cd2907	avconv: add -cpuflags option for setting supported cpuflags. Useful for testing.	13 years ago
Anton Khirnov	39da3b223f	avconv: fix counting encoded video size. avcodec_encode_video2() return value is 0 on success, encoded frame size is stored in the packet.	13 years ago
Anton Khirnov	13f6917ca9	avconv: set discard on input streams automatically.	13 years ago
Anton Khirnov	832ba44d8d	avconv: saner output video timebase. r_frame_rate should in theory have something to do with input framerate, but in practice it is often made up from thin air by lavf. So unless we are targeting a constant output framerate, it's better to just use input stream timebase. Brings back dropped frames in nuv and cscd tests introduced in `cd1ad18a65`	13 years ago
Anton Khirnov	d43040e28b	avconv: refactor vsync code. No functional changes, just make it more readable.	13 years ago
Justin Ruggles	f320fb894c	bethsoftvid: pass palette in side data instead of in a separate packet. Update FATE reference to account for now non-existent palette packet. This also fixes the FATE test if frame data is not initialized in get_buffer(), so update comment in avconv accordingly.	13 years ago
Martin Storsjö	ae5a935574	avconv: Don't split out inline sequence headers when stream copying VC1 This is required when stream copying VC1 in ismv - there's one global header in the moov atom, but keyframes have a separate sequence header prepended. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Andrey Utkin	c22e2ec9d1	avconv: set AVFormatContext.duration from '-t' Set output files duration to recording_time option, if given. Rationale: to save duration into metadata for file that is written to non-seekable output, for formats like FLV (with metadata at beginning). Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Justin Ruggles	a75bc764ec	avcodec: for audio encoding, set packet dts to packet pts. There are no audio encoders which do frame reordering.	13 years ago
Anton Khirnov	8e37038a34	avconv: switch to avcodec_encode_video2().	13 years ago
Anton Khirnov	722410ade5	avconv: estimate next_dts from framerate if it is set.	13 years ago
Anton Khirnov	b34856a116	avconv: better next_dts usage. next_dts is used for estimating the dts of the next packet if it's missing. Therefore, it makes no sense to set it from the pts of the last decoded frame. Also it should be estimated from the current packet duration/ticks_per_frame always, not only when a frame was successfully decoded.	13 years ago
Anton Khirnov	23576b3fbb	avconv: rename InputStream.pts to last_dts. It more accurately describes what does this variable store.	13 years ago
Anton Khirnov	6e98390258	avconv: 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.	13 years ago
Anton Khirnov	3101bb6669	avconv: rename InputStream.next_pts to next_dts. It's used to predict dts, not pts.	13 years ago
Anton Khirnov	1270e12e49	avconv: rework -t handling for encoding. Current code compares the desired recording time with InputStream.pts, which has a very unclear meaning. Change the code to use actual timestamps of the frames passed to the encoder. In several tests, one less frame is encoded, which is more correct. In the idroq test one more frame is encoded, which is again more correct. Behavior with stream copy should be unchanged.	13 years ago
Anton Khirnov	c9af832623	avconv: set encoder timebase for subtitles. The actual number (1/1000) will probably require some discussion/tweaking in the future, but should be good enough for now, since the timestamps in AVSubtitle are in this timebase by definition.	13 years ago
Anton Khirnov	324fbadff9	avconv: remove debugging cruft from do_video_out().	13 years ago
Anton Khirnov	61a099680c	avconv: factorize setting stream_index for the output packet.	13 years ago
Anton Khirnov	d7edd359ec	avconv: deprecate the -deinterlace option Its quality is horrible, yadif should always be used instead.	13 years ago
Mans Rullgard	3715d841a6	Fix non-C89 declarations in for loops Some compilers still do not support this syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
