Hey there!   I am trying to set up a transcoder session, but unfortunately my transcoder keeps dying. Given the couple of line of the log...   Apr 26, 2013 22:43:51 [0xb0628000] DEBUG - [Transcoder] Starting transcoder v306 (t=10s, q=9) Apr 26, 2013 22:43:51 [0xb0081000] DEBUG - [Transcoder] Registered components, about to parse arguments.

Apr 26, 2013 22:43:51 [0xb0628000] ERROR - [Transcoder] Exiting after failure.   ... how can I debug, WHY it got killed? Is there another debug level to show more internal data? ---

Is there another debug level to show more internal data? a few lines above that you will see an entry with the actual transcoder command, manually run it. ---

Thanks! I didn't check that, but found that I picked the wrong "key", thus asking the transcoder to work on metadata... I will try to remember this for next time, probably tomorrow :-) ---
