Justin Ruggles 71ccfb3f14 aac_latm: remove unneeded check for zero-size packet. 
This is already checked by avcodec_decode_audio3()
 2011-10-26 12:21:18 -04:00
Justin Ruggles f1901180e0 pcmdec: fix output buffer size check by calculating the actual output size 
prior to decoding.
 2011-10-26 12:01:07 -04:00
Justin Ruggles 154cd253e5 pcmdec: move codec-specific variable declarations to the corresponding codec 
blocks.
 2011-10-26 12:01:07 -04:00
Justin Ruggles 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.
 2011-10-26 12:01:07 -04:00
Justin Ruggles 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.
 2011-10-26 12:01:07 -04:00
Justin Ruggles 67a3b67c71 pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8. 2011-10-26 12:01:07 -04:00
Justin Ruggles 06af335a33 pcmenc: remove unneeded sample_fmt check. 
It is already checked by avcodec_open2().
 2011-10-26 12:01:07 -04:00
Justin Ruggles d94e29cac9 pcmdec: move number of channels check to pcm_decode_init() 2011-10-26 12:01:06 -04:00
Justin Ruggles 83efd7652e pcmdec: remove unnecessary check for sample_fmt change 2011-10-26 12:01:06 -04:00
Justin Ruggles 381e195b46 pcmdec: move DVD PCM bits_per_coded_sample check near to the code that sets 
the sample size.
 2011-10-26 12:01:06 -04:00
Justin Ruggles 6b94711f15 pcmdec: do not needlessly set *data_size to 0 2011-10-26 12:01:06 -04:00
Justin Ruggles 30f3e7b524 alacdec: remove unneeded NULL or zero-size packet checks. 
This is already done in avcodec_decode_audio3()
 2011-10-26 11:50:17 -04:00
Justin Ruggles 68f7e9cd8e alacdec: simplify buffer allocation by using FF_ALLOC_OR_GOTO() 2011-10-26 11:50:17 -04:00
Justin Ruggles b316af7a7c alacdec: ask for a sample for unsupported sample depths. 
Also return AVERROR_PATCHWELCOME.

Justin Ruggles 63cf54df7a alacdec: cosmetics: use 'ch' instead of 'chan' to iterate channels 2011-10-26 11:50:17 -04:00
Justin Ruggles 01200f1283 alacdec: move some declarations to the top of the function 2011-10-26 11:50:17 -04:00
Justin Ruggles c3a92412c0 alacdec: always use get_sbits_long() for uncompressed samples 2011-10-26 11:50:17 -04:00
Justin Ruggles 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.
 2011-10-26 11:50:16 -04:00
Justin Ruggles dbbb9262ca alacdec: remove unneeded numsamples checks 2011-10-26 11:50:16 -04:00
Justin Ruggles 53df079a73 alacdec: check for buffer allocation failure. 
Also rearranges some functions for easier cleanup on failure.
 2011-10-26 11:50:16 -04:00
Justin Ruggles 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.
 2011-10-26 11:50:16 -04:00
Justin Ruggles 0f26f3d5c4 alacdec: set sample_fmt in alac_decode_init() 2011-10-26 11:50:16 -04:00
Justin Ruggles aec8383348 alacdec: set bytespersample using av_get_bytes_per_sample() 2011-10-26 11:50:15 -04:00
Janne Grunau 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.

Justin Ruggles a3a8572165 g722dec: check output buffer size before decoding 2011-10-25 11:30:50 -04:00
Justin Ruggles 4e41973794 g722dec: cosmetics: reindent/linewrap 2011-10-25 11:30:50 -04:00
Justin Ruggles 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.

Justin Ruggles 2f1d212fd0 tta: check for allocation failure of decode_buffer 2011-10-25 11:22:02 -04:00
Justin Ruggles b5050539c9 tta: use correct frame_length calculation. 
using a floating-point calculation is not necessary.
 2011-10-25 11:22:02 -04:00
Justin Ruggles 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.
 2011-10-25 11:22:02 -04:00

Justin Ruggles b16960a8a5 tta: fix reading of format in TTA header. 
TTA does not support float at all, and format 2 is encrypted TTA.
