* ttadec: fix last frame handling when seekingJustin Ruggles2012-12-221-13/+17
| | | | | | | | | Using a frame count, as is done currently, does not work at all with seeking. Instead, when the number of samples in the final frame has been decoded, we check if only the 32-bit CRC is remaining. If so, we assume that it is the final frame. There is no longer a need to keep total_frames in TTAContext.
* lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov2012-12-041-1/+2
| | | | It will be useful in the upcoming transition to refcounted AVFrames.
* Use proper return values in case of missing featuresDiego Biurrun2012-10-121-1/+1

* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-071-1/+1

* tta: prevents overflows for 32bit integers in header.Ronald S. Bultje2012-05-021-3/+5
| | | | | | | | This prevents sample_rate/data_length from going negative, which caused various crashes and undefined behaviour further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* cosmetics: Align codec declarationsMartin Storsjö2012-04-061-1/+1
| | | | | | | Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
* ttadec: unbreak playback of matroska filesPaul B Mahol2012-03-081-2/+1

* tta: cast output data pointer to the correct typeJustin Ruggles2012-01-171-1/+1
| | | | fixes "warning: assignment from incompatible pointer type"

| | | | Decode to the correct output buffer.
* Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun2011-12-221-1/+1
| | | | | The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
* ttadec: check channel count as read from extradata.Shitiz Garg2011-12-101-0/+5

* Add avcodec_decode_audio4().Justin Ruggles2011-12-021-11/+17
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.

* tta: use correct frame_length calculation.Justin Ruggles2011-10-251-7/+6
| | | | using a floating-point calculation is not necessary.
* tta: add support for decoding 24-bit sample formatJustin Ruggles2011-10-251-22/+34
| | | | | | Note that this will not work in most cases with avconv and avplay due to the AVCODEC_MAX_AUDIO_FRAME_SIZE limit, but it will decode correctly if given a large enough output buffer.
