30f3e7b524 alacdec: remove unneeded NULL or zero-size packet checks. 
This is already done in avcodec_decode_audio3()

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.

cb50329fc5 alacdec: rename 2 functions. 
Now they only do stereo interleaving.

c39bddd392 alacdec: move appending of extra_bits to a separate function. 
This should also fix decoding of mono 24-bit.

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.

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.

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

dcaa83a0fc alacdec: read/validate number of channels from the extradata. 
check frame header channel count against header/container channel count.

47e9c75b36 alacdec: remove unneeded validation of setinfo_sample_size. 
It is already done when using it to set sample_fmt.

d6174bfe5f threads: restore has_b_frames in frame_thread_free 
Otherwise the delay expressed in has_b_frames increases with every
avcodec_close/avcodec_open.
Fixes fate-ea-dct with more than 1 thread.

d0a196962a g722dec: remove the use of lowres for half-rate decoding. 
It is broken because an AVCodecContext can be opened/closed multiple
times, and sample_rate is getting divided by 2 each time that happens.

This removes the only use of lowres for audio.

c6056d4004 tta: add support for decoding 24-bit sample format 
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.

d99fe3a478 mpeg12: fix mpeg_decode_slice context parameter type 
During slice threading only MpegEncContext is passed to
mpeg_decode_slice, remove a wrong cast and change the function
definition to take MpegEncContext pointer.

cd8c64e197 Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context" 
This reverts commit da22ba7df4 since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.
