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.	13 years ago

Justin Ruggles	50c466d609	g726enc: use av_assert0() for sample_rate validation This should never happen, but the check avoids a divide-by-zero.	13 years ago
Justin Ruggles	9e78d8cfdf	g726: treat sample rates other than 8kHz as unofficial.	13 years ago
Justin Ruggles	6e8d4a7afb	g726dec: remove the sample_rate validation	13 years ago
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.	13 years ago
Justin Ruggles	d405237bae	g726: split the init function for the encoder and decoder This also allows for not having a decoder close function.	13 years ago
Justin Ruggles	c8d36d254e	g726: pre-calculate the number of output samples. Allows for checking output buffer size and simplification of decoding loop.	13 years ago
Justin Ruggles	e61a670b53	g726: use int16_t instead of short	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago

Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago
