Pushed the patchset, along with the transpose filter. Tested on all 3 vendors, works fine. AMD requires dedicated allocation, for which I added an error condition. The code was quite ugly in quite a lot of places, so I did touch mostly every line of it in some way. Please fix your quirky, limited hardware next time. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
