Raspberry pi Trixie has no installation candidates for libavformat59 and libswscale6

[arpanghosh8453]

I have listed a few commands and their responses on the recent Raspbian.

>>> sudo apt install libcamera0.5 libmosquitto1 pulseaudio libavformat59 libswscale6 libprotobuf32
Note, selecting 'libprotobuf32t64' instead of 'libprotobuf32'
Package libavformat59 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

Package libswscale6 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

Error: Package 'libavformat59' has no installation candidate
Error: Package 'libswscale6' has no installation candidate

Try libavformat61 and libswscale8; they seem to have updated...?
