no python gstreamer api extract h264 sei

hi,I would like to extract SEI information from an H.264 stream. Can you provide a relevant Python gstreamer demo?

It depends which SEI type you want to watch, but for user data unregistered, they are attached as meta data by the parsers. You can create a pipeline with a parser and an appsink. Pull then samples into python and read theninfo.

For the rest of SEI, you’d have to use the parser library. I’ve never considered using that API outside of C, it may not even have bindings.

Other options, check pyav project, or h26x-extractor.
