Handling VP8 bitstream resolution changes

[Benjamin Trent]

It would seem that the latest gstreamer-1.0 implementation cannot handle
dynamic resolution changes in a VP8 bitstream.

This is evident in not being able to cleanly play a decrypted, demuxed
WebRTC VP8 bitstream coming from Chrome.

The vp8dec element will at times through a segfault, other times would
change the output drastically(only showing part of the image), or would
show image artifacts in the bottom right part of the frame.

Where would this need to be patched? As of right now, it would seem that
the vp8dec element is not complient with the rfc
http://tools.ietf.org/html/rfc6386(see section-9.1) and needs to be updated.

Has anybody else ran into this issue?
