Dynamic text-overlay on live-stream using gst-launch-1.0

[philippe renon]

Did you try with udpsrc ? As per the doc it will timestamp captured buffers and so should not suffer from the issue you have with fdsrc.

"The udpsrc is always a live source. It does however not provide a GstClock,this is left for upstream elements such as an RTP session manager or demuxer(such as an MPEG demuxer). As with all live sources, the captured bufferswill have their timestamp set to the current running time of the pipeline."

At this stage, you next step is to write some C or Python code, and use
appsrc. This way you can create text buffers with generated timestamp
(with or without subparse).
