[Libav-user] HEVCRawSEI?

[lyncher at sapo.pt]

Hi,
In H264 there's a H264RawSEI type that allows creating new SEI messages 
to be added to the video stream.

I was checking if it was possible to add new SEI messages to HEVC video 
stream but I'm not able to find the equivalent object. There's HEVCSEI 
type that has all the possible messages defined, but it would be needed 
a type that has:
     payload_type
     payload_size
     payload

What is the recommended approach to add new SEI messages to a HEVC video 
stream?
Does current libavcodec supports encoding SEI messages to the HEVC video 
stream?

Thanks
