The message above simply means that the v4l2 driver has passed a corrupt
frame to the application (ffmpeg). In this case the application can just
ignore it and continue (it is supposed to be a recoverable error). Apart
from that warning, does the recording work when you play it again?
> And when I go to record, it leaves off where I was before.
What do you mean by that? Also, could you please post the complete output
adding -loglevel debug to your command line?
