Justin Ruggles 02e7dbf5ad adpcm_ima_ws: fix stereo decoding 
Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for
VQA version 2.
 2012-01-24 14:13:46 -05:00
Justin Ruggles 220506d23f avcodec: add a new codec_id for CRYO APC IMA ADPCM. 
The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Justin Ruggles a62c0f94ee adpcmdec: calculate actual number of output samples for each decoder. 
This also allows for removing some of the buf_size checks and using the
sample count for some of the decoding loops.
 2011-10-14 15:53:41 -04:00
Justin Ruggles 439998e18b adpcmdec: check remaining buffer size before decoding next block in the 
ADPCM IMA WAV decoder.
 2011-10-14 15:53:41 -04:00
Justin Ruggles ff5790c761 adpcmdec: do not terminate early in ADPCM IMA Duck DK3 decoder. 
There are still 2 nibbles to decode once the last byte in the packet has been
read. Updated FATE reference.
 2011-10-14 15:53:41 -04:00
Justin Ruggles 8140a1288f adpcmdec: remove unneeded buf_size==0 check. 
This is already done by avcodec_decode_audio3()

Justin Ruggles e562fbd003 adpcm: move codec-specific variable declarations to the sections for the corresponding codecs. 2011-09-29 16:54:01 -04:00
Justin Ruggles 9662539c10 adpcm: check buffer size in Funcom ISS decoder before reading header. 
Also use the post-header data size to control termination of the main
decoding loop.
 2011-09-29 16:54:01 -04:00
Justin Ruggles ba5d2890d7 adpcm: simplify reading of Funcom ISS frame header. 2011-09-29 16:54:01 -04:00

decoding loop.

Justin Ruggles 943f4db552 adpcm_4xm: process planar packets sequentially rather than simultaneously. 
Also properly clip the right channel step_index.
 2011-09-29 16:54:00 -04:00
Justin Ruggles 119974b164 adpcm_ima_wav: process channel-interleaved blocks sequentially rather than simultaneously. 
Speeds up the ADPCM IMA WAV decoder by 15-20% overall.
 2011-09-29 16:54:00 -04:00
Justin Ruggles 7c287b18a0 adpcm: update reference links 
Add Multimedia Wiki link.
Mark dead links with [dead]. Some can still be accessed through archive.org.
Update URLs for pages which have moved.
Replace duplicated links in adpcmenc.c with a note to see the ADPCM decoder
reference documents.

Justin Ruggles ac94b8bcc6 adpcm: simplify packet size bounds checking in the ADPCM IMA QT decoder. 
This is easier to understand. It also avoids returning existing samples mixed
with new samples when the packet is too small.
