[SIPForum-discussion] Getting frame/ethernet header information from a UDP/RTP packet.

[Badri Ranganathan]

Hi all,

Does anyone know any system call to fetch Frame header from a RTP packet?
A RTP packet consists of the following headers -
Frame
Ethernet
IP
UDP
RTP

However, the frame/Ethernet/ip information are left behind by the kernel( I believe) and when I do a recvfrom, I can see only the RTP data. I wish to capture the 'time' from Frame header when the packet arrives.

Thanks,
Badri.
