Didier, I've built the rohc for x86_64 and get the following result on 11.pcap
sudo ./rohc_stats comp smallcid /media/X/Development/tmp/11.pcap STAT "packet number" "context mode" "context mode (string)" "context state" "context state (string)" "packet type" "packet type (string)" "uncompressed packet size (bytes)" "uncompressed header size (bytes)" "compressed packet size (bytes)" "compressed header size (bytes)" STAT 1 1 U-mode 1 IR 0 IR 159 28 158 27 STAT 2 1 U-mode 1 IR 0 IR 28 0 32 4 STAT 3 1 U-mode 1 IR 0 IR 159 28 158 27 STAT 4 1 U-mode 1 IR 0 IR 159 28 158 27 STAT 5 1 U-mode 1 IR 0 IR 28 0 32 4 STAT 6 1 U-mode 2 FO 7 UOR-2 159 28 139 8 STAT 7 1 U-mode 2 FO 7 UOR-2 159 28 137 6 STAT 8 1 U-mode 1 IR 0 IR 28 0 32 4 STAT 9 1 U-mode 2 FO 7 UOR-2 159 28 137 6 STAT 10 1 U-mode 3 SO 2 UO-0 159 28 136 5 STAT 11 1 U-mode 1 IR 0 IR 631 28 631 28 STAT 12 1 U-mode 1 IR 0 IR 651 48 655 52 STAT 13 1 U-mode 1 IR 0 IR 28 0 32 4 STAT 14 1 U-mode 3 SO 2 UO-0 159 28 136 5 How does that look like? BTW, I did now add (this was missed in my driver that is linking to rohc.ko) an implicit enable for UNCOMPRESSED profile, however I do still see error 6 on the UDP packet.

Capture is attached. Yes, they should be compressed with the IP/UDP profile. I tested your capture 11.pcap with the 2.1.0 release. It seems to work fine. Try running the following commands in the 2.1.0 sources: $ ./app/stats/rohc_stats comp smallcid /path/to/11.pcap If it prints some error message, run it again in verbose mode: $ ./app/stats/rohc_stats --verbose comp smallcid /path/to/11.pcap and send me the output. You wrote that IP and UDP profiles are enabled. Did you enable the Uncompressed profile too? If not, it could well explain your problem. The 11.pcap capture contains some ARP packets. Those non-IP packets cannot be compressed by the IP-only and IP/UDP profiles. You need to enable the Uncompressed profile for them.
