* qatar/master: vorbisdec: Rename silly "class_" variable to plain "class". simple_idct_alpha: Drop some useless casts. Simplify av_log_missing_feature(). ac3enc: remove check for mismatching channels and channel_layout If AVCodecContext.channels is 0 and AVCodecContext.channel_layout is non-zero, set channels based on channel_layout. If AVCodecContext.channel_layout and AVCodecContext.channels are both non-zero, check to make sure they do not contradict eachother. cosmetics: indentation Check AVCodec.supported_samplerates and AVCodec.channel_layouts in avcodec_open(). aacdec: remove sf_scale and sf_offset. aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient table values from the spec. Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere. Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway. qpeg: use reget_buffer() in decode_frame() ultimotion: use reget_buffer() in ulti_decode_frame() smacker: remove unnecessary call to avctx->release_buffer in decode_frame() avparser: don't av_malloc(0).
