[gst-devel] Converting MPEG4-GENERIC pcap audio using rtpmp4depay

[shiva varma]

When I use rtpmp4depay to convert MPEG4-GENERIC audio in pcap, I get the
"reason not-negotiated" error

gst-launch filesrc location=audio.pcap ! pcapparse src-ip=10.22.156.148 !
"application/x-rtp, media=audio, clock-rate=48000,
encoding-name=MPEG4-GENERIC" ! rtpmp4gdepay ! fakesink

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal
data flow error.
Additional debug info:
gstbasesrc.c(2550): gst_base_src_loop ():
/GstPipeline:pipeline0/GstFileSrc:filesrc0:
streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

Can you point me to the possible cause of the error

Thanks
-Shiva
