2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-11-02g726dec: add flush() function to reset state when seekingJustin Ruggles
2011-11-02g726: don't pass index to g726_reset()Justin Ruggles
calculate it from c->code_size instead.
2011-11-02g726enc: add private option for setting code size directly.Justin Ruggles
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.
2011-11-02g726: wrap the decoder functions with a CONFIG_ADPCM_G726_DECODER checkJustin Ruggles
2011-11-02g726: group the g726_encoder AVCodec with the other encoding functionsJustin Ruggles
2011-11-02g726: return AVERROR(EINVAL) instead of -1 for invalid channel countJustin Ruggles
2011-11-02g726enc: use av_assert0() for sample_rate validationJustin Ruggles
This should never happen, but the check avoids a divide-by-zero.
2011-11-02g726: treat sample rates other than 8kHz as unofficial.Justin Ruggles
2011-11-02g726dec: remove the sample_rate validationJustin Ruggles
2011-11-02g726: use bits_per_coded_sample instead of bitrate to determine modeJustin Ruggles
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.
2011-11-02g726: split the init function for the encoder and decoderJustin Ruggles
This also allows for not having a decoder close function.
2011-11-02g726: pre-calculate the number of output samples.Justin Ruggles
Allows for checking output buffer size and simplification of decoding loop.
2011-11-02g726: use int16_t instead of shortJustin Ruggles
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.

2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

2009-04-13Rename bitstream.h to get_bits.h.Stefano Sabatini
Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-12Split bitstream.h, put the bitstream writer stuff in the new fileStefano Sabatini
put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames.
