    H.264 hardware decoding failure on Raspberry Pi 5

    RPi5 will never hardware decode H264 media (as it has no H264 hardware decoder) .. so that's incorrect.

    Hard to blind guess what the reason for software decoding to fail is. The log snippet is irrelevant, and the full log is not a debug log so we can't see any of the useful media negotiation info. Go create a a proper debug log.
