Description Jacob Adamson 2017-07-12 19:50:52 UTC 
When completing one of the tutorials for gstreamer, [Basic Tutorial 8](https://gstreamer.freedesktop.org/documentation/tutorials/basic/short-cutting-the-pipeline.html), the pipeline failed to play content with a not-negotiated message.

After a bit of debugging, it turns out the reason was because the appsrc was being configured as a single channel source, and the audiosink only supported 2 channel playback. Changing the caps on the appsrc to 2 channels worked around the problem, but I would have expected the single channel source to be upmixed to 2 channels.

Could you dump the full log into a file, gzip it and attach it here please?

The paste only has the last 50 lines before not-negotiated.

I meant a log where the not-negotiated error happens, before you worked around it :)
