since=20 mesa commit 34f46348438b29e20d06cca312616cfba8ee05f6 For putimage call, if image format is yv12 (or IYUV with U V field swap) and surface format is nv12, then we need to convert yv12 to nv12 and then copy = the converted data from image to surface. We can't use the existing logic where surface is destroyed and re-created with yv12 format. v2 (chk): fix some compiler warnings and commit message=20 mpv --vo=3Dvaapi will produce corrupted output without the new env VAAPI_DISABLE_INTERLACE=3D1 This only applies to s/w decode as hwdec uses nv12 and avoids the conversio= n. Gstreamer vaapisink is not affected as (from what little debugging I did) it doesn't seem to use interlaced buffers doing putimage.
Old bug - mpv --vo=3Dvaapi is unstable with or without the env= on current head and may well have only lucked into apparently working with VAAPI_DISABLE_INTERLACE=3D1 all along. Will open new bug soon(ish). Reverting this commit from head and running with VAAPI_DISABLE_INTERLACE=3D0 seems stable.
