How to Drop GST_EVENT_EOS and continue connecting

[Guru Govindan]

HI Nicolas,
Thanks a lot for your Response.
If I have to recreate the rtspsrc element to recover, temporarily pause the
pipeline and flush everything downstream.
Will the rtspsrc make a new connection with SDP negotiations?
Will that be faster connections than to restart the pipeline?

Just trying to figure out what is the recommended way.

Best Regards,
Guru
