Description

While trying to run mythvidexport via a job, it fails with:

   Traceback (most recent call last):
      File "/usr/local/bin/mythvidexport.py", line 410, in main
        export = VIDEO(opts,int(args[0]))
      File "/usr/local/bin/mythvidexport.py", line 66, in __init__
        self.get_meta()
      File "/usr/local/bin/mythvidexport.py", line 132, in get_meta
        metadata = grab.grabInetref(self.rec.inetref)
      File "/usr/local/lib/python2.7/dist-packages/MythTV/system.py", line 411, in grabInetref
        return self.command('-D', *args).next()
      File "/usr/local/lib/python2.7/dist-packages/MythTV/system.py", line 351, in command
        return self._processMetadata(super(Grabber, self).command(*args))
      File "/usr/local/lib/python2.7/dist-packages/MythTV/system.py", line 137, in command
        return self._runcmd(cmd)
      File "/usr/local/lib/python2.7/dist-packages/MythTV/system.py", line 146, in _runcmd
        raise MythError(MythError.SYSTEM,self.returncode,cmd,self.stderr)
    MythError: External system call failed: code 1

speaking with wagnerrp via IRC, it seems the python bindings may need to be updated to account for recent changes in the metadata handling.

mythvidexport grabs the inetref from the database and it is now something like: ttvdb.py_12345

This breaks the python bindings.

It looks like the problem is here: https://github.com/MythTV/mythtv/blob/master/mythtv/bindings/python/MythTV/system.py#L401-L411

The grabbers are already hard coded into the python bindings: https://github.com/MythTV/mythtv/blob/master/mythtv/bindings/python/MythTV/dataheap.py#L1173-L1174

I added a quick and dirty work around to the mythvideoexport.py script in the MythTV Wiki.

To fix this bug either the VideoGrabber? needs to be re-written, which would probably break even more things, or a check placed in system.py->Grabber.grabInetref() for the new format of inetrefs and strip out the leading grabber name.
