2012-07-30avformat: Drop pointless "format" from container long namesDiego Biurrun
2012-07-23wav: init st to NULL to avoid a false-positive warning.Clément Bœsch
If st is NULL, it means no 'fmt ' tag is found, but 'data' tag (which needs a previous 'fmt ' tag to be parsed correctly and st initialized) check will make sure st is never dereferenced in that case. Fixes warning: libavformat/wav.c: In function ‘wav_read_header’: libavformat/wav.c:499:44: warning: ‘st’ may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
2012-05-21avformat: Add a flag to mark muxers that allow (non strict) monotone timestamps.James Zern
Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
2012-04-06cosmetics: Align muxer/demuxer declarationsMartin Storsjö
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>
2012-02-16libavformat: Add an ff_ prefix to some lavf internal symbolsMartin Storsjö
Prefix the functions/tables brktimegm, pcm_read_seek, dv_offset_reset, voc_get_packet, codec_movaudio_tags, codec_movvideo_tags. After this, lavf has no global symbols without the proper prefix. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-01-27lavf: remove AVFormatParameters from AVFormatContext.read_header signatureAnton Khirnov
2011-11-30lavf: make av_set_pts_info private.Anton Khirnov
It's supposed to be called only from (de)muxers.

Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-10-19lavf,lavd: replace av_new_stream->avformat_new_stream part I.Anton Khirnov
Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'
2011-10-12AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*Anton Khirnov
2011-07-17lavf: use designated initialisers for all (de)muxers.Anton Khirnov
It's more readable and less prone to breakage.

2011-07-13wav: make sure neither data_size nor sample_count is negative.Tomas Härdin
Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-07-13wav: refactor the 'fmt ' tag search and parsing.Tomas Härdin
Moving the search and parsing of the 'fmt ' info the main loop of wav_read_header() allows tags that precede it to be parsed. Creating wav_parse_fmt_tag() makes wav_read_header() easier to read. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-07-13wav: add an option for writing BEXT chunkBenjamin Larsson

Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-04-14handle malloc failures in ff_get_wav_headerMax Horn
ff_get_wav_header is reading data from a WAVE file and then uses it (without validation) to malloc a buffer. It then proceeded to read data into the buffer, without verifying that the allocation succeeded. To address this, change ff_get_wav_header to return an error if allocation failed, and adapted all calling code to handle that error. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2011-04-04avio: introduce an AVIOContext.seekable fieldAnton Khirnov
Use it instead of url_is_streamed and AVIOContext.is_streamed.

2011-03-08avio: deprecate url_feofAnton Khirnov

2011-01-27Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò
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.
