[gst-devel] Help with commandline gstreamer

[Kaustubh Khade]

Hi LRN,

Sorry for the late reply.
I tried the command you suggested, but gstreamer gives me this

'Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...'

and then stalls.

Dont rightly know why this is happening.
I'd encountered this before with my own adaptations and didnt find a reason
why.

Any ideas?
