* / AAC Decoder: support 6.1/7.1 decoded as 5.1Jean-Michel Trivi2013-12-3025-6539/+6522
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add 6.1 and 7.1 channel support including downmixer. Per default the decoder creates a 5.1 channel output for all streams with more than six encoded channels.

* Encoder quantizer fixJean-Michel Trivi2013-08-202-3/+3
| | | | | | | | | | | | | | | | | AAC Encoder: Saturate quantizer shift value to prevent undefined behaviour. In very rare cases the shift value 'totalShift = (16-4)-(3*(totalShift>>2))' can be greater than accu data width. If you apply a shift with more then 31 bit the result depends on the architecture and is not defined in C. For certain platforms zeros are shifted in. That would be our desired behaviour. On other platforms the shift will be applied as modulo. For example >>34 would be applied as >>2. To prevent this discrepancy the shift value is limited/saturated to DFRACT_BITS-1. 'accu >>= fixMin(totalShift,DFRACT_BITS-1)'. Bug 9428126 Change-Id: I27177654c4dc22cf899bc35dad9cdd040dccb02d

| * Don't zero out spec coeffs before doing the final IMDCT.John Grossman2012-09-121-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addresses bug 7140347. When flushing the decoder, you need to make sure to zero out any lingering spectral coefficients as well as zero out the overlap buffer state after decoding the final access unit. Zeroing out the spec coefficients *before* you decode the last block, however, seems like a mistake. If the final block contains any useful information for the stream, then you end up outputting the overlap portion of the second to last decoded block combined with zeros. Because of the shape of the second to last block's windows, this results in what appears to be a fade out, but actually is a zero'ed out final block.
