Make a GST_DEBUG=*:5 log and see if you can spot where the error comes
from (with 'grep -B20 error dbg.log' or so). Something should have
posted a proper error message on the bus, but didn't apparently.

Something must be leaking or building up large caches. If it runs out of
memory quite fast, that might be an indication that you're leaking raw
video buffers, for example.
