Re: [AG-TECH] Not finding Firewire DV on UQ advanced vic

Thanks Chris, sending DV seems to work fine now. The problem now is that when I try and receive it (on another machine) the receiving vic hard freezes (there's the listing for the video with a black thumbnail, and the window is completely frozen - I have to kill the process to stop it). I'll attempt to leave the stream sending (to RIT's AG multicast video address, 224.2.224.225/20002) over the weekend, so if anyone could try receiving it, that would be awesome.

Andrew,

I don't see any multicast traffic on that address - maybe you've stopped sending, or perhaps a highter ttl is needed?

Andrew,

The 404 should be corrected now.

That page has some timps about access to the /dev/raw1394 device
which is what is needed in this case.

One other thing is to ensure the correct vic is actually being run -
cd into thye vic directory and run:
        ./vic ......
rather than just
        vic ......
