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

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