I'm trying to use the preconfigured repos to get ffmpeg working with hardware decrypt. It works fine using software (high CPU) and actually reports the availability of a v4l library for hardware decrypt, but when I try to make use of it bails. As best I can tell, the standard version is not really compatible with the Mali GPU. Apparently others have had plenty of success, using the Mali headers / drivers, via OpenMAX - but I think it's via Ubuntu. Is this working in FriendlyWRT, or a work in progress?

I wanted to attempt to compile it myself, but don't know where to source the headers / drivers for OpenMAX, nor do I even think there are sufficient build tools on the FriendlyWRT release. I don't have Ubuntu installed. Whilst it looks like I could get it working that way, I'd rather stick to the lower overheads of FriendlyWRT, if possible, as I'm simply re-encoding some camera streams, then relaying via Homebridge. Thanks in advance, for any help or pointers.
