[Mjpeg-users] lavrec: setting gain/offset for captured video signal?
by Primoz PETERLIN

Hello everybody,

Once again, I need to digitize some old tapes, so I reactivated my
trusty mjpeg-tools. :)

However, I noticed some of the tapes come out rather washed out when
digitized, i.e., white is almost saturated, and it is difficult to
discern any details (my tapes originate from a phase-contrast
microscope, so they are grayscale to start with).  Do the Zoran-type
cards (I am using DC30) allow any software control over gain and/or
offset?  Is there any user-level possibility to change these settings?

Thank you in advance,
Primož
