Justin Ruggles e49d21306a alacdec: implement the 2-pass prediction type. 
The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.

idroq files.
 2011-12-21 16:51:12 -05:00
Justin Ruggles bc78ceec2b 4xm: remove unneeded check for remaining unused data. 
This is unnecessary complication that only prints a message and does not
affect decoding.
 2011-12-18 13:43:45 -05:00
Justin Ruggles b11ce85664 avplay: don't request a stereo downmix 
Multi-channel output works just fine for me with SDL 1.2.14.
 2011-12-11 14:01:27 -05:00
Justin Ruggles 28101f6c4e flac muxer: fix writing of file header and STREAMINFO header from extradata

Justin Ruggles 1fdf18f4b7 mov: add support for reading and writing the 'chan' tag 
This implements reading the tag in the demuxer and adds support for writing it
in the muxer. Some example channel layout tables for muxing are included for
ac3, aac, and alac, but they are not utilized yet.
 2011-12-09 16:12:58 -05:00
Justin Ruggles b2890f5ed6 audioconvert: add some additional channel and channel layout macros 2011-12-09 16:12:58 -05:00

 2011-12-02 17:40:40 -05:00
Justin Ruggles 560f773c7d avcodec: change number of plane pointers from 4 to 8 at next major bump.

This will allow for supporting more planar audio channels without having to
allocate separate pointer arrays.
 2011-12-02 17:40:40 -05:00
Justin Ruggles ca12401376 fate: split acodec-pcm into individual tests 
this removes 2 redundant tests for pcm in mkv.
we can add the coverage back in later as fate-lavf tests if needed.
 2011-12-01 13:27:56 -05:00
Justin Ruggles 0df5e869cb mpegaudio: do not use init_static_data() for initializing tables. 
It is called once for each mpegaudio codec that is registered, which adds
significant overhead.
 2011-11-27 13:59:34 -05:00
Justin Ruggles 9d2dd356c2 adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() 
It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.
 2011-11-26 17:00:00 -05:00
Justin Ruggles a17c3c7d15 avformat: add CRI ADX format demuxer 2011-11-26 16:25:07 -05:00
Justin Ruggles 27360ccc5e adx: add an ADX parser. 
This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.
 2011-11-26 16:25:07 -05:00
Justin Ruggles d8cec2d7fc adx: move header decoding to ADX common code 2011-11-26 16:25:07 -05:00

Justin Ruggles d1745619db adx: check for unsupported ADX formats 2011-11-26 16:25:07 -05:00
Justin Ruggles 994238536a adx: simplify encoding by using put_sbits() 2011-11-26 16:25:07 -05:00
Justin Ruggles b237248e29 adx: calculate correct LPC coeffs 
Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.
 2011-11-26 16:25:06 -05:00
Justin Ruggles 954d94dd5e adx: use 12-bit coefficients instead of 14-bit to avoid integer overflow 2011-11-26 16:25:06 -05:00
Justin Ruggles c52ddc6024 adx: simplify adx_decode() by using get_sbits() to read residual samples 2011-11-26 16:25:06 -05:00
Justin Ruggles ca9e4727ba adx: fix the data offset parsing in adx_decode_header()

Justin Ruggles c1848c4b26 pcmdec: remove unneeded resetting of samples pointer 2011-11-23 16:26:15 -05:00
Justin RugglesandAnton Khirnov 5872c78122 cdg: skip packets that don't contain a cdg command. 
Signed-off-by: Anton Khirnov <anton@khirnov.net>
 2011-11-23 21:58:10 +01:00
Justin Ruggles 0e8fdd41c2 dsputil: use cpuflags in x86 emu_edge_core 
avoids passing around the extra argument among all the macros it uses
 2011-11-22 15:40:51 -05:00
Justin Ruggles 395f2e70dd dsputil: use movups instead of movdqu in ff_emu_edge_core_sse() 
This allows emulated_edge_mc_sse() and gmc_sse() to be used under
AV_CPU_FLAG_SSE.
 2011-11-22 15:40:51 -05:00
Justin Ruggles 05d1e45d1f wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. 
The initial values are not checked against the number of block sizes.
Initializing them to frame_len_bits will result in a block size index of 0
in these cases instead of something that might be out-of-range.

Fixes Bug 81.
 2011-11-22 13:50:18 -05:00
Justin Ruggles a8fe9a7242 pthread: add some malloc failure checks 2011-11-21 10:18:25 -05:00
Justin Ruggles f3a29b750a avcodec: move some AVCodecContext fields to an internal struct. 
A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.
 2011-11-19 10:01:05 -05:00
Justin Ruggles 513b691955 avcodec: use av_opt_set() instead of deprecated av_set_string3() 2011-11-19 01:14:27 -05:00
Justin Ruggles fa9aeb82e2 avcodec: fix some const warnings 
libavcodec/options.c:583: warning: assignment discards qualifiers from pointer
target type
libavcodec/options.c:589: warning: initialization discards qualifiers from
pointer target type
 2011-11-19 01:10:58 -05:00

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.
 2011-11-11 14:06:14 -05:00
Justin Ruggles ca482ce420 vqf: do not set bits_per_coded_sample for TwinVQ. 
It is a lossy codec with varying quantization, so bits_per_coded_sample is
not applicable.
 2011-11-11 14:06:14 -05:00
Justin Ruggles a8a6da4a0e twinvq: check for allocation failure in init_mdct_win() 2011-11-11 14:06:14 -05:00

This avoids artifically consuming a partial packet but ignoring remaining data
in subsequent calls.
 2011-11-10 10:25:47 -05:00
Justin Ruggles de157f2118 apedec: do not needlessly copy s->samples to nblocks. 
also move nblocks to the local scope where it is used.
 2011-11-10 10:25:47 -05:00
Justin Ruggles 4315c7d35a apedec: check output buffer size after calculating actual output size 2011-11-10 10:25:47 -05:00
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.
 2011-11-10 10:25:47 -05:00
Justin Ruggles 59f4d1b8bb truespeech: use memmove() in truespeech_update_filters() 2011-11-10 10:25:46 -05:00
