is it working in Tinker Board RK3288 ?

I built this with a few modifications on rk3288 board(Tinker OS)

Question. It does not seem to work properly. Does not work on the debian Tinker Board?

This device /dev/v4l/by-path/platform-ff680000.rga-video-index0 does not exist. Anyone found solution?

@johlim hi johlim this demo can run on almost all rk platforms,but you need to modify some places. i dont know the segment fault show in your log occur where,you need to find it first.

sliver-chen commented 5 years ago

@dmitry1945 please confirm if your bsp supports rga driver.

sliver-chen commented 5 years ago

@dmitry1945 rga driver is used to resize yuv,if your bsp don't support it. you can delete mRGA->swscale,but send srcFrm to drm'show.

I did not get a solution for this. But Thank for your reply
