* XXX: The below surface creation may fail on Intel due to:
* https://github.com/01org/intel-vaapi-driver/issues/222
* A permanent fix for that problem will be released in intel-vaapi-driver
* version 1.8.4 and later, and also in 1.8.3-1ubuntu1.
* However if you don't have that fix then a simple workaround is to
* uncomment this line of code:
* size = GST_ROUND_UP_32 (height) * stride[0];
