the error message we get whenever we make videos of 50 minutes and upward. Although the environment above shows high definition variables, this message was found on standard definition recordings of longer than 60 minutes as well. Also, the message is only found whenever the ingestion is set to immediately, and not when set to nightly. It seems as though the problem comes in when the Capture Agent is “preparing the preview” for the next recording.

We battled for quite a while and in the end found the following work-around. In the file /usr/share/galicaster/galicaster/galicaster/recorder/recorder.py we added the following lines of code:

def _on_eos(self, bus, msg): logger.info('eos') time.sleep(30) logger.info('30s Sleep Done') self.stop_preview() # FIXME pipeline set to NULL twice (bf and in the function)

This seemed to stop the message from appearing on all the standard definition recordings, even those ones of 1 hour and 50 minutes. On the high definition setting though, it still appears if the ingestion is set to immediately. If we switch the ingestion setting to nightly, the message disappears, and the Capture Agent keeps on working.

Furthermore, although this message pops up, it seems as though on some occasions, the Capture agent will still record an upcoming scheduled recording. It keeps the red “Error” status up top, and the user interface becomes unusable.

What can be done about this, to give it a permanent fix?
