The YUV channels of VP6 are encoded in a highly linear fashion which does not have any slice-like concept to thread. The alpha channel of VP6A is fairly independent of the YUV and comprises 40% of the work. This patch uses the THREAD_SLICE capability to split the YUV and A decodes into separate threads. Two bugs are fixed by splitting YUV and alpha state: - qscale_table from VP6A decode was for alpha channel instead of YUV - alpha channel filtering settings were overwritten by YUV header parse Signed-off-by: Ben Jackson <ben@ben.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
