Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	13 years ago

Michael Niedermayer	5d47850bbd	dcadec: skip QMF on unused channels When the extra rear channel is present but unused, the s->channel_order_tab[] value for that channel is -1. The QMF can be skipped for the extra channel, and doing so avoids an out-of-array read on s->samples_chanptr[].

Hendrik Leppkes	65219c3851	dca: map xxch side channels to AV_CH_SIDE_LEFT/RIGHT instead of REAR. This fixes decoding of certain 7.1 DTS-HD HRA files, as well as matches the spec better. Table 6-22 in the DTS spec labels the two channels "Left/Right surround on side", and not rear.
