NAK, we can lower the requirements here, but we shouldn't completely 
remove the assert.

Especially since we ignore all of the fields from the 
VASliceParameterBufferMPEG2 structure and so won't catch errors.

Please test something like the following:

assert(buf->size >= (sizeof(VASliceParameterBufferMPEG2) * 
buf->num_elements));

Regards,
Christian.
