ATI HD 7340G

The only decent video format it should handle is h264, and possibly mpeg video. All the rest will have to be decoded by the CPU, which is already a simple & slow to begin with. So forget about h265/hevc, HDR or anything else from today's available features.

AMD apu/gpu support from back in the day wasn't all that great, it was usually a hit or a miss. AMD itself didn't care all that much about Linux then, so video drivers had to be reverse-engineered to make things happen. That has changed since Ryzen came along.

You could also try installing a full blown Linux OS like Ubuntu, and install Kodi itself. The available driver package could help, and perhaps installing AMD's own driver is necessary. But again, support for the older AMD graphics was "meh". Installing it on a bootable USB drive could even prove faster than using the onboard 5400rpm HDD.

So IMHO, in short: if it works (even with an older LibreELEC or even OpenELEC version), fine.

If it doesn't work, you'll have yourself a new techno book end.

its is similar to a AMD E-350 that was slow 3-4 years ago but worked okayish with mpeg/h264. So it might work for those kind of stuff, but don't expect "performance".
