No Video Output With mpv ---hwdec=rkmpp <video> with ffmpeg-mpp

[JFLim1]

Hi @7Ji ,

I don't seems to able to get mpv with vpu hw accelearation working with ffmpeg-mpp. The video output is a blank blue screen with sound. It complains:

[vo/gpu/drmprime] Mapped surface with format 'nv12' has unexpected number of planes. (0 layers and 0 planes, but expected 2 planes)

Appreciate assistance on this. Thank you.

Why do you add ---hwdec=rkmpp? All players utilizing ffmpeg gets hwdec automatically, without interfering, because rkmpp decoders replace the software decoders as the default decoders.

Forcing that in the application just fks up all the logic.

Just mpv file.

Verify that by write 7 to /sys/module/rk_vcodec/parameters/mpp_dev_debug and then watch kernel log with dmesg -w

Thanks for the info. I thought that was necessary to enable "mpv" to enable vpu hw decode and when vpu hw decode is enable mpv will highlight "Using hardware decoding (rkmpp)".

With ffmpeg-mpp and mpv:

The dropped frames is also high.

And example with the same video when vpu hw acceleration is being used. This is from another distro. The output is:

Hi @7Ji,

dmesg has these failures:

[ 9.258343] [drm] failed to init overlay plane Cluster0-win1 [ 9.258345] [drm] failed to init overlay plane Cluster1-win1 [ 9.258348] [drm] failed to init overlay plane Cluster2-win1 [ 9.258350] [drm] failed to init overlay plane Cluster3-win1

basically with "mpv

With "mpv --hwdec=rkmpp

[7Ji]

Just mpv file.
