Since these frames can be user-supplied, this implies that the user-facing API/ABI for AV_PIX_FMT_QSV has changed. It looks like this was broken by using HDLPairs when D3D11 was introduced, which silently changed the existing API for DXVA2 and VAAPI as well. Could someone related to that please document it properly (clearly not all possible valid mfxFrameSurface1s are allowed), and note in APIchanges when the API change happened? - Mark _______________________________________________ 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".
