Up until now, the VAAPI encoder uses fake data with the AVBuffer-API: The data pointer does not point to real memory, but is instead just a VABufferID converted to a pointer. This has probably been copied from the VAAPI-hwcontext-API (which presumably does it to avoid allocations). This commit changes this without causing additional allocations by switching to the RefStruct-pool API.
