Justin Ruggles	59041fd053	g726enc: use AVCodec.encode2()	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	da24963725	g726dec: add flush() function to reset state when seeking	13 years ago
Justin Ruggles	97f5dd1d84	g726: don't pass index to g726_reset() calculate it from c->code_size instead.	13 years ago
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	7abb73d4ba	g726: wrap the decoder functions with a CONFIG_ADPCM_G726_DECODER check	13 years ago
Justin Ruggles	437c11ca16	g726: group the g726_encoder AVCodec with the other encoding functions	13 years ago
Justin Ruggles	50969c0f46	g726: return AVERROR(EINVAL) instead of -1 for invalid channel count	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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	d36beb3f69	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>	14 years ago
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	c7d89948a3	Set a constant frame size for encoding G.726 audio. Originally committed as revision 25107 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	edac49daf5	Use "const" qualifier for pointers that point to input data of audio encoders. This is purely for clarity/documentation purposes. Originally committed as revision 24481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b5f09d31c2	Make sample_fmts and channel_layouts compound literals const to reduce size of .data section. Originally committed as revision 19787 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	b275500706	Split bitstream.h, put the bitstream writer stuff in the new file put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 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. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
