Each time dvgrab and kino are able to read, stream & capture from /dev/raw1394 but in each case VLC errors out saying:
My first question is whether 1394 is working at all under VLC/Linux or whether there is an open bug on this. I have looked on Trac but not found anything.access_dv error: failed to open a Firewire (IEEE1394) connection
main warning: no access module matching "dv" could be loaded
My second question is of course what is going on here that it can't load the module. I infer from the log that it can't load the module bc it can't open the device? No? So the question would then be why can't it open the device when the device seems to work fine under other programs. Here's the full output:
