Subject: basevideocodec: By default don't allow caps changes on the srcpad
X-Git-Tag: 1.19.3~511^2~9496

basevideocodec: By default don't allow caps changes on the srcpad

This fixed playback of Dirac files with schrodec when upstream wants
a different width/height, basevideocodec accepts this and then
pushes buffers with new caps but content of the old caps.
In the best case this will just result in wrong unit size and a
failure in basestransform elements.
