I've been having a problem with transcode 1.1 in PSU mode. After completing the first PSU, it hangs after printing the "sleeping for 3 seconds to cool down" message. When it hangs, the only way to interrupt it is with the KILL signal. This has happened with every VOB file I've thrown at it (some 150 of them).
Adding some strategic log messages, I have determined that it never returns from tc_framebuffer_flush() around line 700 of transcode.c. Further investigation with "-q 7" shows an apparent infinite loop in tc_ring_framebuffer_flush(). Hopefully this helps someone more familiar with the internals of transcode figure out what's happening. -- William Astle
