Description Tim-Philipp Müller 2010-06-23 15:27:39 UTC 
This was brought up on IRC:

  gst-launch-0.10 videotestsrc ! video/x-raw-yuv,format=\(fourcc\)I420 ! videobox top=10 ! xvimagesink

fails to negotiate (errors out with not-negotiated here).

It negotiates I420 as input and YUY2 as output and then fails to find a function to perform the operations on those formats. So when it transforms caps, it returns combinations it can't really handle.

    videobox: Fix negotiation for I420/YV12
    
    We don't support conversion into *all* YUV
    formats for them, only into I420/YV12/AYUV.
    
    Fixes bug #622501.
