Package: luvcview
Version: 1:0.2.4-2
Severity: normal
I've install luvcview and uvccapture as a means of testing a webcam.
Out of the box uvccapture works. But luvcview does not. The errmsgs
are:
penne# luvcview -d /dev/video0
luvcview 0.2.4

Indeed, /dev/fb0 and /dev/fb/0 do not exist. But /dev/video0 does.
If I modprobe vga16fb then it gets slightly further:
penne# luvcview -d /dev/video0
luvcview 0.2.4
SDL information:
Video driver: fbcon
Hardware surfaces are available (64k video memory)
Device information:
Device path: /dev/video0
Stream settings:
Frame format: MJPG
Frame size: 640x480
Frame rate: 30 fps
Segmentation fault

It may well be that I've not done something I should have done or
I need to set FRAMEBUFFER to something, but this information needs
to be passed on to users, and there is nothing in either the man
page or under /usr/share/doc/luvcview.
Ooooorrr ... is this behaviour a bug? :-)

I used to use this program only a few months ago without needing
anything related to frame buffers.
If I can be of assistance testing anything (even instructions to
be added to a README.Debian file) please let me know. Thanks.
