I'm adding user_data_registered_itu_t_t35 SEI messages during an H.264 encoding, and the SEI messages are being stored in the bitstream in the display order instead of encoding order. The encoder is set to accept frames in display order, and the encoded frames are being encoded correctly.
Shouldn't the SEI messages associated with each frame also be in display order? Tracked the problem by adding a sequence byte to each SEI buffer, and the sequence increases for each SEI NAL.
Any idea on what I might be doing wrong?
