* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* g726dec: add flush() function to reset state when seekingJustin Ruggles2011-11-01
|
* g726: don't pass index to g726_reset()Justin Ruggles2011-11-01
| | | | calculate it from c->code_size instead.
* g726enc: add private option for setting code size directly.Justin Ruggles2011-11-01
| | | | | 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.
* g726: wrap the decoder functions with a CONFIG_ADPCM_G726_DECODER checkJustin Ruggles2011-11-01
|
* g726: group the g726_encoder AVCodec with the other encoding functionsJustin Ruggles2011-11-01
|
* g726: return AVERROR(EINVAL) instead of -1 for invalid channel countJustin Ruggles2011-11-01
|
* g726enc: use av_assert0() for sample_rate validationJustin Ruggles2011-11-01
| | | | This should never happen, but the check avoids a divide-by-zero.
* g726: treat sample rates other than 8kHz as unofficial.Justin Ruggles2011-11-01
|
* g726dec: remove the sample_rate validationJustin Ruggles2011-11-01
|
* g726: use bits_per_coded_sample instead of bitrate to determine modeJustin Ruggles2011-11-01
| | | | | | | | | | 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.
* g726: split the init function for the encoder and decoderJustin Ruggles2011-11-01
| | | | This also allows for not having a decoder close function.
* g726: pre-calculate the number of output samples.Justin Ruggles2011-11-01
| | | | Allows for checking output buffer size and simplification of decoding loop.
* g726: use int16_t instead of shortJustin Ruggles2011-11-01
|
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann2009-04-07
| | | | | | | | | | | 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.
