Description Johannes Bauer 2011-07-30 13:34:03 UTC 
When trying to render a video as a Matroska video, PiTiVi always hangs at the "Rendering movie/Estimating..." screen while at the command line a python stacktrace is thrown:

+ Trace 227957

gst.LinkError: failed to link bin17 with ffenc_dvvideo0 

Hitting "Cancel" has no effect. Closing the "Rendering" dialog does not reenable controls (like menu), so basically PiTiVi is unusable at this point (can't save or do anything).

It seems you're trying to use ffmpeg DV video in a matroska container? What happens if you use a different video ecodec?

Also, what version of pitivi is this?
Comment 2 Johannes Bauer 2011-07-31 11:18:16 UTC 
Yes, you are correct. If I select another video codec (e.g. Theora), it works fine (just tried that out). It just happens that ffmpeg DV is the default video container when creating a new video.

The version I'm using is git, latest commit was aa684103541d2478d9d31390b181ea461fc5f94f.

Ok then this is a duplicate of 640245.
