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
Mans Rullgard	6501dcfb5e	Remove unnecessary inclusions of [sys/]time.h 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
Martin Storsjö	a1a6cdc26e	avconv: Display the error returned by avformat_write_header Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	0629f6128e	avconv: rename transcode_audio/video to decode_audio/video. Those functions do only decoding now, encoding is run from poll_filters().	13 years ago
Anton Khirnov	39885a4bd7	avconv: reindent	13 years ago
Anton Khirnov	74b961db77	avconv: replace -vsync cfr code with the fps filter. Invented timestamps for the h264 tests return to something resembling sanity. In the idroq-video-encode test when converting 25 fps -> 30 fps the fifth frame gets duplicated instead of the sixth.	13 years ago
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
