no access module matching "dv" could be loaded
Posted: 19 Jan 2010 23:15
Running into this issue under 1.0.2, 1.0.3, 1.0.4 & 1.1 on 2 different systems (Debian/AMD64 & Ubuntu/AMD64 using both Karma & Lucid)
Each time dvgrab and kino are able to read, stream & capture from /dev/raw1394 but in each case VLC errors out saying:
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:
irc #videolan had the suggestion to add debugging to dv.c (although I am surprised it didn't already have it) however it seems like I should first check if this is a known issue or if there were other approaches to resolving it.

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
