As a quick run down on the whole set: - This does fix decoding of frame-coded samples (ie. fate-vc1_sa10091 and fate-vc1_sa20021) on NVIDIA using DXVA2, no regressions using DXVA2 are known - This does fix decoding of these samples on Intel GPUs using VAAPI, however it appears to break on AMD using VAAPI. Important to note here however is that this change is matching up with the vaapi spec, and the AMD implementation is more or less hacky. - VDPAU seems to overall be unimpressed and keeps working as before. I hope I summarized the non-DXVA2 cases properly, as I didn't test those personally, but relied on data from Mark Thompson. Despite the breakage of AMD VAAPI decoding, this change appears to be correct in the sense that it matches the VAAPI and DXVA2 specs on how to handle slices and fixes decoding on two different GPUs, using those two APIs. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
