Fbdevsink Low Framerate on Raspberry Pi

[Dave Johnstone]

Hi,

I'm having a hard time compiling on the Pi2 - lots of make errors, so I 
tried the Raspbian Jessie packages but these are quite out of date.  Is 
there some repo for up-to-date Raspbian packages or do I need to 
persevere with the build process?

Regards,

Dave.
