Anton Khirnov	44b0b85fe9	avconv: prefer user-forced input framerate when choosing output framerate	13 years ago
Anton Khirnov	3c0df90584	avconv: make -shortest a per-output file option.	13 years ago
Mans Rullgard	d752509b74	Use log2(x) instead of log(x) / log(2) Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	ab29609701	avconv: allow no input files. It is now possible to use lavfi sources.	13 years ago
Anton Khirnov	a5fd7c607f	avconv: prevent invalid reads in transcode_init()	13 years ago
Anton Khirnov	57d2422559	avconv: rename OutputStream.is_past_recording_time to finished. The new name is shorter and more accurate, since this variable is no longer used only for checking recording time constraint.	13 years ago
Anton Khirnov	0c00fd80ee	avconv: split the code for processing input packets out of transcode()	13 years ago
Anton Khirnov	f154ef1ae5	avconv: send EOF to lavfi even if flushing the decoder fails	13 years ago
Anton Khirnov	cc2133b66a	avconv: get rid of pointless temporary variable.	13 years ago
Anton Khirnov	8391602913	avconv: simplify transcode(). Operate with a pointer to InputFile instead of its index in input_files.	13 years ago
Anton Khirnov	c0fbf9713c	avconv: cosmetics Replace for (;foo == 0;) with while (!foo) This is prettier.	13 years ago
Anton Khirnov	0b26ef4228	avconv: replace no_packet array in transcode() with a var in InputStream This simplifies splitting code for reading from input out of transcode().	13 years ago
Anton Khirnov	d64901f99d	avconv: remove commented out cruft.	13 years ago
Anton Khirnov	a4f5011065	avconv: maintain sync on lavfi outputs. Before this commit, poll_filters() reads all frames available on each lavfi output. This does not work for lavfi sources that produce an unlimited number of frames, e.g. color and similar. With this commit, poll_filters() reads from output with the lowest timestamp and returns to wait for more input if no frames are available on it.	13 years ago
Anton Khirnov	fe2147e936	avconv: split configuring filter configuration to a separate file.	13 years ago
Anton Khirnov	f5e668273a	avconv: split option parsing into a separate file.	13 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Mans Rullgard	82494835c4	rational: add av_inv_q() returning the inverse of an AVRational This allows simplifying a few expressions. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	aba232cfa9	lavf: deprecate r_frame_rate. According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.	13 years ago
Ronald S. Bultje	dcb7ef5483	avprobe/avconv: fix tentative declaration compile errors on MSVS.	13 years ago
Anton Khirnov	5417efbbf3	avconv: print an error message when demuxing fails. Also exit in such a case if -xerror is used. Fixes bug 329.	13 years ago
Anton Khirnov	8a645bfc31	avconv: propagate fatal errors from lavfi.	13 years ago
Anton Khirnov	53ddd43f0c	avconv: use only meaningful timestamps in start time check.	13 years ago
Anton Khirnov	b98c8f4f2b	avconv: fix the check for -ss as an output option. start time is already substracted from the frame timestamp, so it needs to be checked against 0, not start time.	13 years ago
Reimar Döffinger	4c679750cb	avconv: fix parsing of -force_key_frames option. Currently it always exits with an error when more than one position is specified. CC: libav-stable@libav.org	13 years ago
Martin Storsjö	715129cdc4	avconv: Set audio filter time base to the sample rate If the output frame size is smaller than the input sample rate, and the input stream time base corresponds exactly to the input frame size (getting input packet timestamps like 0, 1, 2, 3, 4 etc), the output timestamps from the filter will be like 0, 1, 2, 3, 4, 4, 5 ..., leadning to non-monotone timestamps later. A concrete example is input mp3 data having frame sizes of 1152 samples, transcoded to aac with 1024 sample frames. By setting the audio filter time base to the sample rate, we will get sensible timestamps for all output packets, regardless of the ratio between the input and output frame sizes.

Martin Storsjö	d3ed1c9571	cmdutils: Pass the actual chosen encoder to filter_codec_opts This allows passing the right options to encoders when there's more than one encoder for a certain codec id. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	c29c1a1b6b	avconv: add an assert to silence an uninitialized variable warning. The warning silenced was: avconv.c: In function ‘opt_output_file’: avconv.c:3380:21: warning: ‘meta_out’ may be used uninitialized in this function [-Wuninitialized] avconv.c:3315:20: note: ‘meta_out’ was declared here	13 years ago
Anton Khirnov	74853ed3f8	avconv: shut up an uninitialized variable warning. The warning silenced was: avconv.c: In function ‘configure_filtergraph’: avconv.c:603:8: warning: ‘ist’ may be used uninitialized in this function [-Wuninitialized] avconv.c:549:18: note: ‘ist’ was declared here	13 years ago
Anton Khirnov	b8c632a720	avconv: don't include vsrc_buffer.h, which doesn't exist anymore	13 years ago
Anton Khirnov	19ad567311	avconv: fix -force_key_frames parse_forced_keyframes() relies in encoder timebase being set, so call it from transcode_init() after it is known.	13 years ago
Anton Khirnov	fd269d6253	avconv: remove a forgotten debugging printf.	13 years ago
Anton Khirnov	df98bf22cb	avconv: use more descriptive names for hardcoded filters. Also ensure that all such filters get a non-NULL name. Should fix FATE failures on some architectures after `58b049f2fa`.	13 years ago
Anton Khirnov	6fc7d9a078	avconv: remove redundant handling of async. Because of a mistake during merging the code for simple and complex filtergraphs, -async inserts an asyncts filter both on input and output. Remove the output hunk.	13 years ago
Mans Rullgard	896bb0d742	Replace usleep() calls with av_usleep() This reduces the dependency on unistd.h which is not available on all systems. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Anton Khirnov	9034b0ed66	avconv: don't try to free threads that were not initialized.	13 years ago
Anton Khirnov	9d0bfc5052	lavfi: make AVFilterPad opaque after two major bumps. It will allow adding new fields to it without ABI breaks.	13 years ago
Anton Khirnov	47b812e9ce	avconv: support only native pthreads. Our w32pthreads wrapper has various issues and is only supposed to be used in libavcodec.	13 years ago
Anton Khirnov	5db5169e46	avconv: multithreaded demuxing. When there are multiple input files, run demuxing for each input file in a separate thread, so reading packets does not block. This is useful for achieving low latency when reading from multiple (possibly slow) input streams.	13 years ago
Anton Khirnov	d55c2e05b5	avtools: move buffer management code from avconv to cmdutils. It will be used by avplay.	13 years ago
Anton Khirnov	3ffa233595	avconv: don't use InputStream in the buffer management code. Use just the pointer to the head of the buffer pool. This will allow sharing the code with avplay.	13 years ago
Anton Khirnov	e58b75f7ff	avconv: fix exiting when max frames is reached. frame number should never be strictly larger than max frames, so the if() was never triggered.	13 years ago
Anton Khirnov	bb7431f4fc	avconv: check output stream recording time before each frame returned from filters There may be multiple frames returned, so with just one check we can write more than requested to the output.	13 years ago
Anton Khirnov	a508e7a1ff	avconv: split selecting input file out of transcode().	13 years ago
Anton Khirnov	2f51ec2b94	avconv: split checking for active outputs out of transcode().	13 years ago
Anton Khirnov	c9cc76290f	avconv: extend -r to work on any input stream. This is done by automatically inserting a setpts filter.	13 years ago
Anton Khirnov	cf6c38c62b	avconv: don't print filters inserted by avconv in stream mappings.	13 years ago
Anton Khirnov	8daf21d567	avconv: merge configuration code for complex and simple filters Some tests change because -s now inserts the scaler to the end instead of beginning of the filtergraph.	13 years ago
Anton Khirnov	a977d91e28	avconv: split configuring input filters out of configure_complex_filter	13 years ago
