It is due to the limitation in MSDK mentioned in commit message: If pipeline contains resize, mirroring and other, VPP skips other filters in MSDK. And specially for resize (also width/height swap caused by rotate), MFXVideoVPP_Init would fail directly, not simply skip the resize/rotate: https://github.com/Intel-Media-SDK/MediaSDK/blob/master/_studio/mfx_lib/vpp/src/mfx_vpp_hw.cpp#L5546 This PR could handle this properly as suggested: https://github.com/Intel-Media-SDK/MediaSDK/pull/1491 - linjie _______________________________________________ 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".
