deinterleave: allow switching between 1 channel configs
requested to merge ocrete/gst-plugins-good:186-deinterleave-allow-switching-between-1-channel-configs into master
Here is an old patch that we never merged for some reason, it seems very safe. Let's merge it unless someone yellsé
Allow switching between 1 channel configs regardless of whether they're positioned, since positioning with a 1 channel stream doesn't change anything.
Closes #186 (closed)
