Michael Chinen	a4151444bd	Define FLAC_MIN_FRAME_SIZE and use it in the FLAC decoder. Patch by Michael Chinen [mchinen at gmail] Originally committed as revision 25916 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Chinen	60a684939a	Simplify the FLAC decoder now that it no longer has to parse arbitrary raw FLAC data thanks to the recently added FLAC parser. Patch by Michael Chinen [mchinen at gmail] Originally committed as revision 25915 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Chinen	3c795698d0	Add log_level_offset parameter to ff_flac_decode_frame_header(). It will be used to optionally silence the error messages. Patch by Michael Chinen [mchinen at gmail] Originally committed as revision 25912 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Chinen	625daac4bd	Move decode_frame_header() from flacdec.c to flac.c/h to share with the forthcoming FLAC parser. Patch by Michael Chinen [mchinen at gmail] Originally committed as revision 25909 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	2e0559b713	Support decoding of FLAC files without a STREAMINFO header. Originally committed as revision 25315 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	4c1645a458	Set sample format in flac_decode_init() rather than in ff_flac_parse_streaminfo() since the latter is shared with the raw FLAC demuxer, which should not be setting the sample format. Originally committed as revision 20430 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	78a9a77eac	add CODEC_CAP_SUBFRAMES to the FLAC decoder capabilities. also add a FIXME comment as a reminder that we can remove both capabilities once a parser is implemented. Originally committed as revision 19891 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	8313e17976	flacdec: change variable-length array to fixed length pred_order can never exceed 32, so always allocating that amount is safe and not very wasteful. Originally committed as revision 19669 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	ce863d7f36	Rename ff_log_missing_feature() to av_log_missing_feature(). Originally committed as revision 19294 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	e2a38af96e	flacdec: change frame bps validation to return an error value if bps changes since this is not currently supported by the decoder. Originally committed as revision 18157 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	492cc392fa	10l: don't check against current layout until after validating ch_mode. should have been in last commit. Originally committed as revision 18154 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
