Gstreamer. Multiple pcap to avi

[Vivia Nikolaidou]

Hi,

It looks like some files are out of order, or rtpjitterbuffer thinks
so. Instead of using mergecap, try having GStreamer read each separate
pcap file with multifilesrc and see if the problem persists.

Also, maybe some pcap files are corrupt? Try skipping a few files when
merging them (e.g. the first two?) and see if you can get it to work.

Best regards,

Vivia
