Videcore libs not working to render video Raspberry Pi 3B+

[hemantbaxi]

Describe the bug I have installed latest Raspbian Full version (bullseye) on Raspberry Pi 3B+.

I was trying to install RPiPlay. That works for audio but failed to render the video. It uses OpenMAX. So, I thought I should first try running examples from vc hello_pi itself and found those are also failing for video.

I have copied /opt/vc directory from this repository to the Raspberry. I have same issue with both stable and master branch.

To reproduce cd /opt/vc/src/hello_pi sh rebuild.sh

Expected behaviour Build should pass for all the examples. hello_video should show some video hello_videocube show show again some video.

Actual behaviour

1. Build Problem When I try to build hello_pi using sh rebuild.sh. I got following error first.

I fixed this error by adding -lEGL and -lGLESv2 to Makefile.include LDFLAGS. However, it now stopped at following error.

These are standard calls and the required flags for the same are there in hello_fft makefile i.e. -ldl -lm . So, I wonder where it is failing.

• Runtime error Since build for hello_video and hello_videocube had passed, I thought to run those. When I ran ./hello_video.bin test.h264

It didn't show any video, didn't show any error and then existed in few seconds without showing any message.

Same happened when I tried ./hello_videocube.

OpenMAX is not supported on Bullseye. There are standard linux methods for achieving similar behaviour (v4l2/mesa/drm).

This repo (and the rpi-update tool) still supports buster, so it's useful keeping the files present here, but they won't be installed by default on a new bullseye image.
