In pitivi, we have both diracenc and shroenc showing up as "Dirac" in the video codecs list (the full descriptive name would be "Dirac Encoder" for both, but we strip out redundant words such as "Encoder").
According to what I've been told on #gstreamer, the difference is that one is based on libschroedinger, one on libdirac from the BBC; both encode the Dirac video format.
The question is, what should we do about this on the pitivi side (if anything)?
Manually hide one of them? File a bug in gst requesting that the names be more differentiated?
