New question #181472 on rohc:
https://answers.launchpad.net/rohc/+question/181472
hello,
I test the rohc library. I input the command "test -c rohc.pcap smallcid source.pcap" and I get the right result. But when I input the command "test -o ofilename.pcap -c rohc.pcap smallcid source.pcap". Bug appears as follow:
