Janne Grunau 29ae0565d9 vble: remove vble_error_close 
It does not make much sense to factor the error handling to its own
av_always_inline function. Fixes "format not a string literal and no
format arguments" warning in the av_log.

Derek Buitenhuis c433a3f9a5 VBLE Decoder 
Add a decoder for the VBLE Lossless Codec, which
still has a cult following. Used to be popular
several years ago on doom9.

Justin Ruggles e79da63282 dpcm: remove unneeded buf_size==0 check. 
It is already checked in avcodec_decode_audio3()

Justin Ruggles 9d06037d48 twinvq: add SSE/AVX optimized sum/difference stereo interleaving 2011-11-11 14:13:58 -05:00
Justin Ruggles 7b966566da vqf/twinvq: pass vqf COMM chunk info in extradata 
This is needed because the twinvq decoder cannot rely on bit_rate to be set.
The API documentation says that bit_rate is set by libavcodec, not by the
user.

Justin Ruggles c298b2b8db apedec: consume the whole packet when copying to the decoder buffer. 
This avoids artifically consuming a partial packet but ignoring remaining data
in subsequent calls.

Justin Ruggles de157f2118 apedec: do not needlessly copy s->samples to nblocks. 
also move nblocks to the local scope where it is used.

Justin Ruggles ad17207b51 apedec: remove unneeded entropy decoder normalization. 
The decoder already skips data at the end of the packet without this.
Also remove 2 APEContext fields that were only used for the end-of-frame
normalization.

Justin Ruggles 41899b9acb vorbisdec: remove AVCODEC_MAX_AUDIO_FRAME_SIZE check 
The user could provide a larger buffer, which is already checked separately
before writing output.

Justin Ruggles f1f6d3615f avcodec: add support for planar signed 8-bit PCM. 
It is found in some 8svx files (e.g. ones created by SoX).
Currently the decoder reuses the 8svx functions because we already have
handling of a single large planar packet for the compressed 8svx codecs.

Justin Ruggles fed5ca255f ra144enc: add sample_fmts list to ff_ra_144_encoder

sample format if needed.

shahriman AMS 4344ce08f1 vc1dec: Partial rewrite of vc1_pred_mv() 
The current code is a generalization of the earlier progressive MV
prediction code. This was supposed to predict MVs for both interlaced
and progressive pictures. But the interlaced MV prediction is buggy
and works mostly by luck.

This partially fixes interlaced MV prediction.
