Hi everybody, Right now I have 2 USRP (version 1) boxes, and did some experiments on realtime video. I first used tunnel.py in /gnuradio/gnuradio-examples/python/digital to set up a virtual connection between two USRP boxes (by assigning non-existing IP addresses to them). Then used VLC to stream video file between this two boxes via UDP (we can let VLC stream video to another PC by specifying its IP address). The video quality on the receiver is pretty bad. I first streamed a 12M video between this tunnel, but only got a black screen popped up. Then I tried a 1.6M video, and got one frame displayed but then the video stuck there and didn't get played any more. I'm wondering if it's because of the limitation of USB, or the extra overhead of tunnel setup? If I want to improve the video quality, which part should I start to improve? or should I use other methods to get the problem solved?
