7.5 MPP Hardware Encoding
Encode H.264 and mux it into MP4:
gst-launch-1.0 videotestsrc num-buffers=600 \
! 'video/x-raw,format=NV12,width=640,height=320,framerate=60/1' \
! mpph264enc \
! h264parse \
! qtmux \
! filesink location=h264.mp4Encode H.265 and mux it into MP4:
gst-launch-1.0 videotestsrc num-buffers=600 \
! 'video/x-raw,format=NV12,width=640,height=320,framerate=60/1' \
! mpph265enc \
! h265parse \
! qtmux \
! filesink location=h265.mp4JPEG encoding:
gst-launch-1.0 videotestsrc num-buffers=1 \
! 'video/x-raw,format=NV12,width=640,height=320' \

| Property | Description |
|---|---|
rc-mode | Bitrate control mode: vbr, cbr, or fixqp |
bps | Target bitrate; ignored in fixqp mode |
bps-min, bps-max | Minimum and maximum bitrates |
gop | I-frame interval; when the default is -1, it is normally set according to the frame rate |
qp-init, qp-min, qp-max | Quantization parameters; a lower QP generally means higher quality and a higher bitrate |
profile, level | H.264/H.265 profile and level |
width, height, rotation | Scaling or rotation may be performed through RGA |
arm-afbc | Enable when the input data is AFBC |
Check properties and their accepted values with gst-inspect-1.0 <encoder> on the target system.
