b46e58f741 alacdec: remove unneeded local variable 2011-10-26 11:50:17 -04:00
Justin Ruggles
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.
 2011-10-26 11:50:17 -04:00
Justin Ruggles
cb50329fc5 alacdec: rename 2 functions. 
Now they only do stereo interleaving.
 2011-10-26 11:50:16 -04:00
Justin Ruggles
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.

53df079a73 alacdec: check for buffer allocation failure. 
Also rearranges some functions for easier cleanup on failure.

e5e4f92b5c alacdec: allocate per-channel buffers based on channel count. 
reduces memory usage when the stream has fewer than MAX_CHANNELS
 2011-10-26 11:50:16 -04:00
Justin Ruggles
dcaa83a0fc alacdec: read/validate number of channels from the extradata. 
check frame header channel count against header/container channel count.
 2011-10-26 11:50:16 -04:00
Justin Ruggles
47e9c75b36 alacdec: remove unneeded validation of setinfo_sample_size. 
It is already done when using it to set sample_fmt.

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.

bits_per_coded_sample but that cannot be done seperately.
Patch by Luca Abeni
Also reset the minor version and fix the forgotton change to libfaad.
Note: The API/ABI should not be considered stable yet, there still may
be a change done here or there if some developer has some cleanup ideas and
patches!
