MFC encoder does not support dmabuf-import. This is a problem when transcoding using MFC decoder, e.g.:
gst-launch-1.0 filesrc location=bunny_trailer_1080p.mov ! parsebin ! v4l2video4dec capture-io-mode=dmabuf ! v4l2video3h264enc output-io-mode=dmabuf-import extra-controls="encode,h264_level=10,h264_profile=4,frame_level_rate_control_enable=1,video_bitrate=8000000" ! h264parse ! matroskamux ! filesink location=transcoded.mkv won't work. Are there any plans for dmabuf import on MFC encoder? --- Either I've been missing something or nothing has been going on. (K. E. Gordon)
