[Bug 966294] Re: Ubiquity loops forever from ubiquity_webcam_play

[Stéphane Graber]

For anyone else interested in tracking down this bug as I'm not going to
be around until Tuesday, the current assumption is that something in the
core of gstreamer is causing the regression.

As it only happens on a subset of hardware, the guess would be that it has to do with the encoding/decoding part that may take a different path depending on the pixelformat/resolutions supported by the webcams.
luvcview -L can help figuring that out.
