# Run multimedia sample applications

The multimedia sample applications provide custom use cases that realize the camera, video, audio, graphics, and display capabilities of Qualcomm Linux.

Note

For camera and video sample applications that require a YUV player, see [Sourceforge YUV player project](https://sourceforge.net/projects/raw-yuvplayer/).

## Troubleshooting

- **Camera**: For any application, if the camera service doesn’t work or fails during execution, see [Camera troubleshooting](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-17/troubleshooting.html) to restart it.
- **Display**: If you face issues with the display, run the following command in the terminal of the target device to configure the display:

export XDG_RUNTIME_DIR=/dev/socket/weston && export WAYLAND_DISPLAY=wayland-1 && weston --continue-without-input
        Copy to clipboard
