is mpp_linux_cpp project still working? #496

Open ywangwxd opened 6 months ago

Hi, I followed the readme file and found the mpp_linux_cpp repo, its last update was 6 years ago. I tried to make it compile successfully, but running is failed. Here is the error message when execute the binary using sudo

failed to open rga dev /dev/v4l/by-path/platform-ff680000.rga-video-index0.
failed to exec mRGA->init -1.
failed to init codec

I could find /dev/v4l at all.

So what is the problem?

Do not use rga in mpp. Use librga instead.

Do not use rga in mpp. Use librga instead.

Then the other sample projects which are not working should not be listed in the readme. It is misleading.
