Does the nvv4l2h264enc plugin for Orin nx 16g support SEI data encapsulation?

[jack.yan]

hardware: DevelopKit/Custom board

software version: JetPack5.1.3/JetPack5.1.5

My business function hopes to encapsulate some data into encoded data through SEI and forward it through RTSP/RTMP, but I don’t know if adding SEI data is supported in nvv4l2h264enc, and the maximum number of bytes of SEI data that can be added?

Hi,
There’s no existing implementation in nvv4l2h264enc plugin. You may download source code and implement the function.
Source code is in the package:

Jetson Linux Release 36.5 | NVIDIA Developer
Driver Package (BSP) Sources

If nvv4l2h264enc does not support SEI data insertion, does x264enc support SEI data insertion?

Hi,
It does not show SEI related properties when running $ gst-inspect-1.0 x264enc. Probably it is not supported in the software encoder also. Would see if other users can check and comment.

Hi jack.yan,

In case you’re interested we have a product that handles the insertion and extraction of SEI data from a h264/h265 stream: GstSEIMetadata

This doesn’t require any changes to the nvv4l2h264enc.
