the code

e49d21306a alacdec: implement the 2-pass prediction type. 
The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.

e76c7b856f alacdec: fill in missing or guessed info about the extradata format. 
Now that there is official documentation from Apple about this, we don't have
to guess anymore.

7080533cda alacdec: remove the numchannels parameter from several functions. 
They only operate on stereo content, so the extra param is not necessary and
also allows for simplifying the code.

c39bddd392 alacdec: move appending of extra_bits to a separate function. 
This should also fix decoding of mono 24-bit.
 2011-10-26 11:50:16 -04:00
Justin Ruggles
e739d35156 alacdec: split stereo decorrelation into a separate function. 
It is identical for 16-bit and 24-bit, so there is no need to have duplicate
code.
 2011-10-26 11:50:16 -04:00
Justin Ruggles
d251c85dce alacdec: cosmetics: rename 'wasted_bits' to 'extra_bits'. 
The bits are not wasted, they are additional low bits that are added to the
16-bit decompressed samples to increase the output sample depth.

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.
