I have a series of videos with custom information encoded in the sei message NAL. Is it possible to read that information when decoding using the Nvidia hardware decoder. If it is not supported, should I use FFMPEG compiled with NVENC support instead?
UPDATE: I want to decode the media and read the SEI message. I am streaming live video and including postprocessing info in the sei message. The client has to use that info to apply effects to the decoded media. Decoding the media as quickly as possible is important, and I want to do it in hardware. I assume that the Nvidia decoder must parse the NAL units to decode them. I would like to avoid duplicating work if possible.
