I am trying to stream a video over a wireless network using UDP
For that, I started tests in the following sequence:
Test 1: VLC ---- VLC
Test 2: VLC ---- Gnuradio (using udp source and udp sink blocks
only) ---- VLC
Test 3: VLC ---- Gnuradio (with a complete communication model (e.g.
mod/demod)) ---- VLC
Test 4: VLC ---- Gnuradio ---- USRPs (multiple) ---- VLC
Test 1 completed successfully and the streamed video quality is perfect
the receiver end. Whereas, in test 2, test 3 and test 4 I’ve
successfully got the streamed video at the receiver end but the quality
not good (it’s even more degraded when shift to the
higher test levels). During the testing a warning message
appeared on gnuradio console i.e. Too much data; packet loss.
I tried to resolve this issue by adjusting the factors like payload
size and sampling rate but nothing works. The flowcharts and the video
are attached here for reference.
Furthermore, can anyone give me a hint that how can I check
the parameters like throughput, packet delay and SNR.
Kindly assist me and point out the mistake I’ve made, waiting for
