  • how to use ffmpeg with mjpeg_vaapi encoder (with hardware acceleration) ?

    8 août 2018, par Marat

    When I use ffmpeg with mjpeg encoder without hardware acceleration, everything works fine. I use following command :

    ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg -vframes 1 pipe:1

    But, when I try to use mjpeg with hardware acceleration, I always get error :

    ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg_vaapi -vframes 1 pipe:1
