Get the latest 0.4 sources from subversion here:
http://ivtvdriver.org/viewcvs/ivtv/branches/0.4.tar.gz?view=tar
I've removed the confusing max_* settings. It should now look only at
the mpg_buffers, vbi_buffers, etc. options.
Let me know if you still run into troubles with this version.
Note that I'm not sure whether you can safely set the number of buffers
to 0 in ivtv-0.4, but you can certainly set it to 1 for streams you
don't use.
Okay, I'll try that. I've been holding off on compiling a new ivtv
'cause I assumed (until yesterday) that its buffering would be easy
to change and was actually changing, and didn't want to possibly
destabilize an otherwise-working system. But I think it's now worth
going for the version and hoping the buffering works better; if so,
that might be enough to solve my problems with that (20-second-plus!)
scheduler query. Thanks!
(Won't have results until at least Monday afternoon 'cause I don't
have a maintenance window on the machine until then.)
