Vittorio Giovara	4407054ff0	adx: convert to new channel layout API Signed-off-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: James Almer <jamrial@gmail.com>	3 years ago
Andreas Rheinhardt	58ca07320b	avcodec/adxdec: Mark decoder as init-threadsafe Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Andreas Rheinhardt	ef6a9e5e31	avutil/buffer: Switch AVBuffer API to size_t Announced in `14040a1d91`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago

Michael Niedermayer	34f5a59ad5	avcodec: Set AV_CODEC_CAP_CHANNEL_CONF in more decoders Suggested-by: Paul B Mahol <onemda@gmail.com> See: [FFmpeg-devel] [PATCH 1/3] avcodec/fastaudio: Check channels Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 years ago
Paul B Mahol	92396cee60	avformat: add CRI AAX demuxer	4 years ago
Andreas Rheinhardt	340e6b0185	avcodec/adxdec: Remove unnecessary left-shift Replace "(a * (1 << shift) * b + c) >> shift" by "a * b + (c >> shift)". It is equivalent to the old code because a is in the range of uint16_t, shift is 12 and b is effectively a signed 4-bit number, so that no overflow/truncation of high bits happens during the multiplication (overflow would be undefined anyway).

Anton Khirnov	d5cf5afabb	adxdec: get rid of an avpriv function The only thing the demuxer needs is the sample rate to set the timebase, which can be simply read with AV_RB32.	11 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
Justin Ruggles	9d2dd356c2	adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() It is used by the ADX decoder, and therefore needs to be exported in order to work with shared libs.	13 years ago
Justin Ruggles	27360ccc5e	adx: add an ADX parser. This simplifies the decoder so it doesn't have to process an in-packet header or handle arbitrary-sized packets. It also fixes decoding of files with large headers.	13 years ago

Justin Ruggles	b237248e29	adx: calculate correct LPC coeffs Instead of using fixed coefficients, the correct way is to calculate the coefficients using the highpass cutoff frequency from the ADX stream header and the sample rate.	13 years ago
Justin Ruggles	954d94dd5e	adx: use 12-bit coefficients instead of 14-bit to avoid integer overflow	13 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
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.

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
