154cd253e5 pcmdec: move codec-specific variable declarations to the corresponding codec 
blocks.

0093f96d34 pcmdec: return buf_size instead of src-buf. 
The values will always be the same, so this change eliminates an unneeded
variable. It also gets rid of the need to reset src when memcpy() is used.

85579b6381 avcodec: remove the Zork PCM encoder. 
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.

67a3b67c71 pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8. 2011-10-26 12:01:07 -04:00

06af335a33 pcmenc: remove unneeded sample_fmt check. 
It is already checked by avcodec_open2().

381e195b46 pcmdec: move DVD PCM bits_per_coded_sample check near to the code that sets 
the sample size.

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.
 2011-10-26 11:50:17 -04:00

cb50329fc5 alacdec: rename 2 functions. 
Now they only do stereo interleaving.
 2011-10-26 11:50:16 -04:00

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.

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.

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.
