Sorry for requesting a feature on the mailing list, I couldn't find any
other method of doing this.
Anyhow I'd like to request 2 simple features for the up coming cincv 2.2
release that I think would be good for the whole community.
Auto save
and native shuttle/job support.
This is a great feature! It makes the editing process so easy. Here is
some code that I found on the web that works really well as a stand
alone program. I know I should submit a patch but I can't get cincv 2.2
to compile because of v4l support being removed from the kernel... and
well I'm not really much of a C coder.....
Best Regards
Eric
