#9206: ffmpeg goes into interruptible sleep because of temporary network problem
and can not recover

Reporter: Jarno Suni | Type: defect

Summary of the bug:
How to reproduce:
{{{
% ffmpeg -i http://stream.wappuradio.fi/wappuradio.opus -c copy
output.opus
}}}
I had some temporary problem in internet connection or my the router, and
probably due to that ffmpeg was waiting for some data to arrive. When
internet connection started to work again, ffmpeg did not continue
recording but remained in interuptible sleep state. I killed the process
by SIGINT. I will tell you later, if I can reproduce the issue, but I
think the bug and fix can be found by analyzing the code.
Expected behavior:
Option 1:
ffmpeg should exit with non-zero error code
Option 2: ffmpeg should be able to continue recording automatically when
possible even if some part of the recording was missed. ffmpeg should
somehow notify caller that some part was missed.
NOTE: There has been some breaks in the input stream before, but then
ffmpeg exited so I can relaunch it automatically periodically, if needed.
Maybe there are some ffmpeg options I can use the make it work better for
me in these kind of problem cases?
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
