7.4 MPP Hardware Decoding
Select the decoder automatically:
gst-play-1.0 --flags=3 --videosink=waylandsink test.mp4When mppvideodec has a sufficiently high rank and supports the input format, automatic pipeline selection will normally choose the MPP decoder. For troubleshooting, explicitly specify it:
gst-launch-1.0 filesrc location=test.mp4 \
! parsebin \
! mppvideodec \
! waylandsinkJPEG hardware decoding:
gst-launch-1.0 filesrc location=input.jpg \
! jpegparse \
! mppjpegdec \
! filesink location=output.yuvCommon mppvideodec properties:
