Nicolas George	276fcbde6c	lavf: data muxer and demuxer. Allow to use tools designed to work with demuxers, muxers and packets (for example ffmpeg itself) to process raw byte streams (like aviocat).	12 years ago
Paul B Mahol	4c76600a8c	rawdec: make use of AV_OPT_TYPE_VIDEO_RATE Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago

Janne Grunau	54c7fe6d68	raw demuxer: initialize end of partial packets	12 years ago
Luca Barbato	587874ef1c	rawdec: remove ff_raw_read_header It is not used anymore and is a kludge.	12 years ago
Luca Barbato	5f0e161dd6	g722: refactor out of rawdec.c	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago

Clément Bœsch	16dc5f2050	Replace various inlined inverse AVRational with av_inv_q().	12 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.	12 years ago
Michael Niedermayer	fdc371114f	ff_raw_audio_read_header: mark as AVSTREAM_PARSE_FULL_RAW Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	9d87c8e6f8	rawdec: use av_assert() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1dd71e1cd5	rawdec: force timestamps from codec to be used This fixes playback timing with at least m4v files Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	20234a4bd7	cosmetics: Align muxer/demuxer declarations Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	87d7a92b62	rawdec: set timebase to 1/fps.	13 years ago
Anton Khirnov	f7fe41a04f	lavf: rename AVInputFormat.value to raw_codec_id. It's only used by raw demuxers for storing the codec id.	13 years ago
Anton Khirnov	6e9651d106	lavf: remove AVFormatParameters from AVFormatContext.read_header signature	13 years ago
Reimar Döffinger	efd6b80b40	rawdec: use av_shrink_packet. This fixes reads of uninitialized data by the parser when running FATE sample h264-conformance/SL1_SVA_B.264. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	c914038d38	rawdec: Set start_time to 0 for raw audio files. None of the raw audio files have timestamps, thus setting start_time to 0 should be reasonable. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	e745d7525a	rawdec: don't set codec timebase. It's not supposed to be set outside of lavc. Set r_frame_rate and avg_frame_rate instead.	13 years ago
Anton Khirnov	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Michael Niedermayer	fca85ce5ec	rawdec: use a default sample rate if none is specified. Fixes "ffmpeg -f s16le -i /dev/zero" Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1d23e5246c	mjpeg: support mpo Fixes stereoscopic_photo.mpo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	87c57d807f	Create separate functions for the raw GSM demuxer. Put the new raw GSM demuxer in its own file. Fixes raw GSM demuxing.	13 years ago
Stefano Sabatini	aa638b4600	rawdec: add check on sample_rate Prevent error condition in case sample_rate is unset or set to a negative value. In particular, fix divide-by-zero error occurring in ffmpeg due to sample_rate set to 0 in output_packet(), in code: ist->next_pts += ((int64_t)AV_TIME_BASE * ist->st->codec->frame_size) / ist->st->codec->sample_rate; Fix trac ticket #324.	13 years ago
Anton Khirnov	3b3bbdd3e6	lavf,lavd: replace av_new_stream->avformat_new_stream part I. Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'	13 years ago
Justin Ruggles	e32dfdaa8d	shn: do not allow seeking in the raw shn demuxer. The demuxer does not read the seektable, a parser is not possible without a full decode, and no shorten decoder can handle random seeking because it needs side info from the seektable.	13 years ago
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Janne Grunau	dcb9f6a20d	Add LATM demuxer This is a raw demuxer for the AAC LATM decoder and thus limited to single stream LOAS.	13 years ago
Anton Khirnov	85d982f1e2	rawdec: refactor private option for raw video demuxers pixel_format/video_size only apply to 'rawvideo' (==uncompressed) demuxer and make no sense for the other raw (== containerless) demuxers. Keep only the framerate option for those. Also use unique classes for all raw video demuxers	13 years ago
Anton Khirnov	34d2bf30a0	pcmdec: use unique classes for all pcm demuxers.	13 years ago
Anton Khirnov	d906f49aa8	rawdec: g722 is always 1 channel/16kHz	13 years ago
Anton Khirnov	c14fe6bc99	lavf,lavd: remove all usage of AVFormatParameters from demuxers. AVFormatParameters are converted into corresponding private options in av_open_input_file/stream() compat wrappers, so accessing them from demuxers is redundant.	13 years ago
Anton Khirnov	dfc2c4d900	lavf: use designated initialisers for all (de)muxers. It's more readable and less prone to breakage.	14 years ago
Anton Khirnov	367732832f	lavf,lavc: free avoptions in a generic way. It's simpler and less error-prone. Fixes some memleaks along the way.	14 years ago
Anton Khirnov	e762b1ce95	rawdec: add framerate private option.	14 years ago
Anton Khirnov	1f94c31f69	rawdec: initialize return value to 0.	14 years ago

Anton Khirnov	2a85f21868	rawdec: add a pixel_format private option.	14 years ago
Anton Khirnov	fa4924a358	rawdec: factor video demuxer definitions into a macro.	14 years ago
Anton Khirnov	973f686a6c	rawdec: add video_size private option.	14 years ago
Anton Khirnov	bffd4dd1d3	lavf: deprecate AVFormatParameters.{channels,sample_rate}.	14 years ago
Anton Khirnov	5b3865fc5f	rawdec: add sample_rate/channels private options.	14 years ago
Reimar Döffinger	7f725f234e	Set start_time to 0 for raw audio files. None of the raw audio files have timestamps, thus setting start_time to 0 should be reasonable.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Anton Khirnov	384c9c2fa7	avio: add avio_tell macro as a replacement for url_ftell Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> (cherry picked from commit `a2704c9712`)	14 years ago

Anton Khirnov	d4e321d9c2	avio: make get_partial_buffer internal. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> (cherry picked from commit `b3db9ceef1`)	14 years ago

Diego Elio Pettenò	66355be3c3	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts. (cherry picked from commit `c6610a216e`)	14 years ago
