How to split an image or video into a number of packets?

Hi all,

I want to transmit an image/video from one node to another node using
GNUradio, but I don’t know how to divide an image or video into multiple
packets. I want to make it real time in the sense that an image/video is
loaded, divided in to multiple packets and then transmitted
Can any one tell me how to do this in GNUradio?
Thank you very much

If I understand correctly you want to stream a video from one node to
other. You could use VLC for that and UDP source and sink in GNU Radio.

Basically use a UDP Source on the sender side and use VLC to stream a
to the UDP source’s port.
On the receiver side, use a UDP Sink and use another instance of VLC to
receive a stream for the UDP sink’s port.

This is a really open question. How do you want to transmit? If you use
OFDM, you can simply prepend a stream to tagged stream block.
