[Live-devel] [External] Re: Randomly I Frame missed for high bitrate cameras

[R, Ranjith]

Hi Ross,

I confirmed in Wireshark that all packets are received from the network(both network and send buffer is ruled out).

I increased the receive buffer size up to 2MB, still the issue is observed.

I am not sure how to proceed further.


Thanks and Regards,
Ranjith

Packets are not being discarded anywhere in the LIVE555 code.  Note that a LIVE555-based server simply sits in a loop, writing a sequence of RTP packets to a socket.  And a LIVE555-based receiver simply sits in a loop, reading a sequence of RTP packets from a socket.

In other words, there is nothing in the LIVE555 code that can possibly be ‘losing’ packets.  If you are seeing packet loss between a LIVE555-based server and a LIVE555-based client, then it *must* be happening between these two sockets (server socket and client socket) - not in the LIVE555 code.

I.e., if your server and client are separated by a network, then any packet lost *must* be occurring on the network, or in the operating system that’s underneath the server’s socket, or in the operating system that’s underneath the receiver’s socket.

If your server and client are running on the same computer (either on the same (real or virtual) machine, or in different virtual machines), then any packet lost *must* be occurring within the computer’s operating system (including perhaps its virtualization implementation).
