James Almer	7c9d2ad45f	avcodec/dca: remove GetBitContext usage from avpriv_dca_parse_core_frame_header() This prevents potential ABI issues with GetBitContext. Reviewed-by: foo86 <foobaz86@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	7 years ago
foo86	3b7ec920af	avformat/dtsdec: switch to common frame header parsing function This makes probing for regular DTS more strict because more header fields are checked and values not supported by decoder are now rejected. Also fixes an issue original code had with 14-bit streams: 96 bits of header were expected, however only 84 bits were converted, which was not enough to parse LFE flag.

foo86	191dd219d9	avformat/dtsdec: Extend DTS core sync word Check extended sync word for 16-bit LE and BE core streams to reduce probability of alias sync detection. Previously sync word extension was checked only for 14-bit streams. This follows up the similar change in avcodec/dca_parser. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	0dba982bb4	avformat/dtsdec: dts_probe: check reserved bit, check lfe, check sr_code similarity Fixes misdetection of s16le Fixes Ticket4109 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	6a44699746	avformat/dtsdec: check more of the dca headers in dts_probe() Fixes misdetection of 664461_flac_16_44100_2.wav Fixes Ticket3830 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	2b501b553f	avformat/dtsdec: skip the first 4k in dts_probe() DTS primarly needs to be separated from PCM, and PCM can contain cliping and overshoots at the very start which can mimic DTS headers. If this isnt sufficient then more of the DTS stream has to be decoded and analyzed Fixes ticket3784 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 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	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	dfc2c4d900	lavf: use designated initialisers for all (de)muxers. It's more readable and less prone to breakage.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	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
