This snap of VLC is specifically created for the Raspberry Pi, it includes the MMAL (Multi-Media Abstraction Layer) VLC patches from https://github.com/RPi-Distro/vlc, an MMAL patched version of FFmpeg as found at https://github.com/RPi-Distro/ffmpeg and the accelerated videocore binaries from https://github.com/raspberrypi/firmware.

Please make sure your user is in the "video" group to gain access to the /dev/vchiq device. If you have problems with fullscreen playback on a Pi4 or Pi400, make sure your screen is connected to the correct HDMI output (this VLC can only play fullscreen on one of them).

Please make also sure to have the "hardware-observe" interface connected via

 sudo snap connect vlc-pi:hardware-observe

This snap is still experimental and requires to be installed with the --devmode flag until https://github.com/snapcore/snapd/pull/9804 has been fixed in snapd.
