OMXplayer is deprecated in Raspian Bullseye.

[OzRocky]

When running the install script on the recently released version of Raspian (Bullseye), we get the following message:

Package omxplayer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'omxplayer' has no installation candidate

When you try to run the demo, you get the following message:

OMXplayer not installed but required!

According to the OMXplayer Github, it is being depreciated.

I've installed recently Raspian Bullseye (2022-09-22-raspios-bullseye-armhf-lite.img) on my Raspberry PI 2, in order to use Raspi Camplayer.
Of course no OMXplayer player available in Raspian Bullseye repositories, but it is still possible to install it from raspian archive and it does works on Bullseye :)
You also have to install libraries for communication with OMXplayer that are no more part of the system: libbrcmEGL, libbrcmGLESv2, libopenmaxil.

Here is the complete sequence I used to get it to work:

wget -P /tmp https://archive.raspberrypi.org/debian/pool/main/o/omxplayer/omxplayer_20190723+gitf543a0d-1+bullseye_armhf.deb
dpkg -i /tmp/omxplayer_20190723+gitf543a0d-1+bullseye_armhf.deb
apt install -y --fix-broken

cd /usr/lib/arm-linux-gnueabihf
curl -sSfLO 'https://raw.githubusercontent.com/raspberrypi/firmware/master/opt/vc/lib/libbrcmEGL.so'
curl -sSfLO 'https://raw.githubusercontent.com/raspberrypi/firmware/master/opt/vc/lib/libbrcmGLESv2.so'
curl -sSfLO 'https://raw.githubusercontent.com/raspberrypi/firmware/master/opt/vc/lib/libopenmaxil.so'
