Justin Ruggles da24963725 g726dec: add flush() function to reset state when seeking 2011-11-01 21:23:04 -04:00
Justin Ruggles 97f5dd1d84 g726: don't pass index to g726_reset() 
calculate it from c->code_size instead.

Justin Ruggles 615b2a2cf5 g726enc: add private option for setting code size directly. 
This is an easy alternative to setting bit_rate. This patch also selects the
closest bit_rate to the requested one rather than requiring an exact value.

Justin Ruggles 7abb73d4ba g726: wrap the decoder functions with a CONFIG_ADPCM_G726_DECODER check 2011-11-01 21:23:04 -04:00
Justin Ruggles 437c11ca16 g726: group the g726_encoder AVCodec with the other encoding functions 2011-11-01 21:23:04 -04:00

Justin Ruggles 50c466d609 g726enc: use av_assert0() for sample_rate validation 
This should never happen, but the check avoids a divide-by-zero.

Justin Ruggles 9e78d8cfdf g726: treat sample rates other than 8kHz as unofficial. 2011-11-01 21:23:03 -04:00
Justin Ruggles 6e8d4a7afb g726dec: remove the sample_rate validation 2011-11-01 21:23:03 -04:00
Justin Ruggles 6ac34eed54 g726: use bits_per_coded_sample instead of bitrate to determine mode 
This requires some workarounds in the WAV muxer and demuxer. We need to write
the correct bits_per_coded_sample and block_align in the muxer. In the
demuxer, we cannot rely on the bits_per_coded_sample value, so we use the bit
rate and sample rate to determine the value.

This avoids having the decoder rely on AVCodecContext.bit_rate, which is not
required to be set by the user for decoding according to our API.
 2011-11-01 21:23:03 -04:00
Justin Ruggles d405237bae g726: split the init function for the encoder and decoder 
This also allows for not having a decoder close function.
 2011-11-01 21:23:03 -04:00
Justin Ruggles c8d36d254e g726: pre-calculate the number of output samples. 
Allows for checking output buffer size and simplification of decoding loop.

Martin Storsjö 02170990fd cmdutils: Rename read_file to cmdutils_read_file

statically to that library.

Diego Biurrun 45235d69c2 libdirac/libschroedinger: Drop unnecessary symbol prefixes. 
The names used in the libdirac/libschroedinger wrappers are long enough as-is.
Bloating them with unnecessary prefixes makes them even more unwieldy.

Justin Ruggles 44d2a982ac dsicin: fix several audio-related fields in the CIN demuxer 
bits_per_coded_sample should be 8.
block_align is calculated incorrectly, but it is not needed anyway.
packet pts should be calculated in samples.
packet duration can be set.

Kostya Shishkov 46e1af3b0f utvideo: handle empty Huffman trees 
If the frame is filled with the same colour, encoder may produce no data
and the fill value is indicated by zero code length (the rest of symbols
will have 0xFF for code length, meaning invalid).  So such Huffman trees
should be treated specially.

Justin Ruggles 425a843505 binkaudio: change short to int16_t 2011-10-29 15:16:54 -04:00
Justin Ruggles 4f4e19480a binkaudio: only decode one block at a time. 
This prevents truncating output due to an output buffer that is too small for
all blocks. There is no limit on the number of blocks in a packet.
 2011-10-29 15:16:54 -04:00
Justin Ruggles eaddd29e00 binkaudio: store interleaved overlap samples in BinkAudioContext. 
This fixes the requirement for the buffer size to be larger than the number of
samples actually decoded.
