png of hanging pipeline

I am trying to re-encode an Ogg file with Vorbis and Theora to an Ogg file with Vorbis and Theora. It just seems to stall. Looking at the dot file dump it seems something strange is happening with the Theora stream inside encodebin, as it ends up with caps ANY for the last leg of the pipeline. Attached Png showing situation.

As a test I transcoded an mp4 file into Ogg and that worked fine. But trying to re-encode the resulting Ogg file to Ogg again just stalls. If I choose to drop the video, then it works fine, so it is definitely related to Theora.

Attached png image, only thing I am wondering if is wrong in it, is that the caps inside encodebin for theora seems to get set to ANY at some point.

I think it is caused by this bug now fixed in git:

Confirmed, this works fine now, thanks Wim.
