Getting hardware accelerated decoding is extremely tricky, in the next OpenHD Release it will be included. On the current images it doesn't work and just installing it on a prebuild image will also not work.

If you want to use the Rock5 as ground you should be able to just do it with one of the images we provide for the platform.

For now, I know how to lunch QOpenHD in rock5 with eglfs. I want to use the hardware decoder, so I need to start rock5_h264_decode.service as video layer and the rock5_qopenhd.service as ui layer.

the service can lunch success, but the ui layer is not render transparent, so the video layer is not visiable.
I know this is not a problem about QOpenHD, so just close this issue.
