Ok, this finally happened again today while watching live tv. And my
fix worked. On the select timeout, the device was closed, reopened,
and recording continued. I only lost about 1-2 seconds of the
recording, but then it continued with no problems until the end of the
program. I'd like some feedback on this before I go opening a ticket
for this. I think the more interesting issue is why this timeout
occurs during a recording in the first place. I wasn't able to find an
explanation for this so this patch is the next best thing I could come
up with and, most importantly, it works by allowing an in-progress
recording to continue instead of just dumping the printf over and over
until the program ends.
Here's my diff for the fix:
