Compositor sink stream synchronisation

Hi Tim,

Many thanks for your reply.
I haven't tried setting min-latency on the appsrc but I have tried 
"latency=20000000" on the imxcompositor_g2d element and that certainly 
seems to fix my issue and is the fix I am currently using.

But as this has been an intermittent problem, I may have just moved the 
barn door a bit, hence the questioning to see if those in the know think 
that my problem is due to this and what is actually the proper way of 
handling it (should I be setting a latency value on the beamdeinterlace 
element for example?).
