Hi there,
I was work on PSP04.00.01.13_patch2 and tried to see if the new v4l2 capture driver works.
Whenever I run ./saLoopBack app, I always saw a bunch of complain messages, which didn't
show up in the following runs. But no video came out at all. So I had no idea if video
data has been captured.
Could anyone shed some light in this?
Thanks,
-Perry
