|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * qatar/master: ac3dec: fix processing of delta bit allocation information. vc1: fix fate-vc1 after previous commit. wmv3dec: fix playback of complex WMV3 files using simple_idct. make av_dup_packet() more cautious on allocation failures make containers pass palette change in AVPacket introduce side information for AVPacket Politic commits that have not been pulled: Update regtest checksums after revision 6001dad. Replace more FFmpeg references by Libav. Replace references to ffmpeg-devel with libav-devel; fix roundup URL. Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * ac3dec: fix processing of delta bit allocation information.Justin Ruggles2011-04-171-2/+2
| | | | | | | | | | The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.

| * ac3: Remove ff_ac3_critical_band_size_tab.Justin Ruggles2011-01-261-13/+4
| | | | | | | | | | | | | | It is only used to generate band_start_tab, which about the same size, at runtime, so it's simpler just to always hardcode band_start_tab. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | | | This symbol is only ever used to calculate the non-hardcoded tables, so only enable it in that case, and static to the source unit that uses it. Signed-off-by: Mans Rullgard <mans@mansr.com>
