I don't think we have any coverage at all, especially considering
there were 1 or 2 patches fixing vdec not working at all in the past
few months.. Maybe CrOS has some internal pipelines for this.

Don't think they're even made anymore!

Personally I've done:

- boot and check if venus still probes and doesn't shout in dmesg
- decode and re-encode a H264 file

which is far from perfect..
