Mans Rullgard	44c56a1617	flacdec: simplify sample buffer handling Pass pointer to sample buffer instead of channel number to various functions called from decode_subframe(). Also simplify a few expressions within this function.	12 years ago

Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Mans Rullgard	bf1cf4d5a5	flacdec: reverse lpc coeff order, simplify filter Reversing the lpc coefficient order simplifies indexing in the filter. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	87466f8124	flacdec: factor out code setting avctx->sample_fmt	13 years ago
Mans Rullgard	93e7ef9a24	flacdec: allocate sample buffers with av_malloc The buffers are only allocated once, although it can happen from any of a few different places, so there is no need to use realloc. Using av_malloc() ensures they are aligned suitably for SIMD optimisations. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	0da301e105	flacdec: remove curr_bps from FLACContext This value does not need to be persistent across calls.	13 years ago

Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago

Anton Khirnov	d9cca9fc6a	lavc: use avpriv_ prefix for some flac symbols used in lavf. Specifically, ff_flac_parse_streaminfo, ff_flac_is_extradata_valid and ff_flac_parse_block_header	13 years ago
Justin Ruggles	4c5e7b27d5	flacdec: fix buffer size checking in get_metadata_size() Adds an additional check before reading the next block header and avoids a potential integer overflow when checking the metadata size against the remaining buffer size.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Diego Biurrun	ad4cd0c2a4	doxygen: use Doxygen markup for authors and web links where appropriate	14 years ago

Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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	fbc4d9c964	flacdec: cosmetics: separate the pure frame header parsing code from other frame header decoding code Originally committed as revision 18166 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	1448907465	flacdec: cosmetics: indentation Originally committed as revision 18159 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	f91eaf5deb	flacdec: cosmetics: add some braces to if/else statements Originally committed as revision 18156 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	b6fa746e39	flacdec: skip frame when allocated data size is too small Originally committed as revision 18155 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
Justin Ruggles	7660dc6f4f	flacdec: give a more accurate error message when validating channel layout. differentiates between invalid values and unsupported values. Originally committed as revision 18153 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	02b26d2d5c	flacdec: move data size check to flac_decode_frame() Originally committed as revision 18151 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
