Struct mfxPayload 

#[repr(C)]
pub struct mfxPayload {
    pub CtrlFlags: mfxU32,
    pub reserved: [mfxU32; 3],

}

Describes user data payload in MPEG-2 or SEI message payload in H.264.

For encoding, these payloads can be inserted into the bitstream. The payload buffer must contain a valid formatted payload.

For H.264, this is the sei_message() as specified in the section 7.3.2.3.1 ‘Supplemental enhancement information message syntax’ of the ISO/IEC 14496-10 specification.

For MPEG-2, this is the section 6.2.2.2.2 ‘User data’ of the ISO/IEC 13818-2 specification, excluding the user data start_code.

For decoding, these payloads can be retrieved as the decoder parses the bitstream and caches them in an internal buffer.
