Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Justin Ruggles	ec2694d259	g722dec: set channel layout at initialization instead of validating it	12 years ago

Martin Storsjö	d58dd4b5b5	avopt: Store defaults for AV_OPT_TYPE_FLAGS in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Martin Storsjö	b087ce2bee	g722: Fix the QMF scaling This fixes clipping if the encoder input used the full 16 bit input range (samples with a magnitude below 16383 worked fine). The filtered subband samples should be 15 bit maximum, while the code earlier produced them scaled to 16 bit. This makes the decoder output have double the magnitude compared to before. The spec reference samples doesn't test the QMF at all, which was why this part slipped past initially. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	6fcbb0f553	g722dec: Signal skipping the lower bits via AVOptions instead of bits_per_coded_sample This avoids using bits_per_coded_sample for this information. bits_per_coded_sample should be 4 for this codec normally, since two samples are encoded into one 8 bit codeword. In principle, this might be info that needs to be passed from a demuxer, and in that case, a private AVOption isn't the best choice, but no such samples are available at the moment, so that use case is purely theoretical at the moment.

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	a3a8572165	g722dec: check output buffer size before decoding	13 years ago
Justin Ruggles	4e41973794	g722dec: cosmetics: reindent/linewrap	13 years ago
Justin Ruggles	d0a196962a	g722dec: remove the use of lowres for half-rate decoding. It is broken because an AVCodecContext can be opened/closed multiple times, and sample_rate is getting divided by 2 each time that happens. This removes the only use of lowres for audio.	13 years ago
Justin Ruggles	704721bc9c	g722: split decoder and encoder into separate files	13 years ago
