Building and enabling GstVideotimecode plugin

Hi,

Is GstVideotimecode available as a plugin?
https://gstreamer.freedesktop.org/documentation/video/gstvideotimecode.html?gi-language=c


Our understanding was that if should be part of gst-plugins-base package (
https://github.com/GStreamer/gst-plugins-base/blob/master/gst-libs/gst/video/gstvideotimecode.h),
but when we compile and install it, the videotimecode is not available.

Is there any other available plugin for adding SEI timecodes to the video?


Thanks,
Gil
