error with streaming and saving muxed audio and video data

[Marka Reddy]

hi,

I am using gstreamer for streaming and storing muxed audio and video from
camera and mic on embedded hardware through ethernet.

on sender side pipeline is :
v4l2src ! encoder ! matroska mux ! udpsink
alsasrc ! encoder ! mux

on receiver :
udpsrc ! filesink

 i am running the pipeline on both sides and stopping them later with EOS
and playing the stored file..

the issue is it works often on the first run of the pipeline..most of the
times i am generating a file but cannot play it
it gives " couldnot determine type of stream "error
please help
