libav error while decoding MB

[Shishigami]

I'm really at my wits end, using the exact same configuration as before I get
different errors now:

A quick test from the command line shows that it can open my webcam without
issue though:

gst-launch-1.0 -v ksvideosrc ! videoconvert ! fpsdisplaysink

I'm sorry if I'm just being stupid, but I'm really lost
