Hi guys. Don't mean to be picky or anything but won't this change cause a non-backward compat ABI/API breakage ? While adding modulo_time_base might be ok (highly dependant on the implementation which may use the vop_fields union without sanitising it), vop_time_increment is definitely going to c

2014-10-30 Thread Varga, Michael
Hello, I am working to implement VAAPI mpeg4 decoding in MESA. I am currently trying to remedy a scenario where the VideoObjectPlane() (VOP) header is truncated from the input slice data. If the VOP header is truncated I need to regenerate it and add it to the front of the bitstream. It would a
