Try transcoding to a format your existing hardware can accelerate.
You didn't say what graphics card / video playback profile you are
using. You will need to look at that first, to determine
"what formats" it'll support.
Given you are speculating about adding a graphics card, then I would
hazard a guess you have an embedded intel gpu. So try running `vainfo`
