Im using the sdk to write out OpAtom mxf files that include VC3 essence data. My problem now is that the Element key for the Picture element is wrong. It is set to 060e2b34 01020101 0d010301 00000000. The zeros at the end being the problem. According to the standard the last four bytes should be based on element count, wrapping etc.
Is there any way for me to control the key that is used on the essence element in the MXF? The key used now is causing Avid to reject the file.
You may be able to use IAAFKLVEssenceDataParameters::SetElementKey or IAAFKLVStreamParameters::SetElementKey.
