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	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
