I understand your m3u8 patch, and have already enabled the relevant option.
av_dict_set(&options, "m3u8_hold_counters", "0", 0);
I think it has indeed helped to get rid of one place where I block, but
there appear to be several., The stack that it's being blocked on now is
DNS-related. I would have assumed that the AVIOInterruptCB would have
worked for that too, but it hasn't.
Perhaps timeouts are the wrong approach? I really just need a way to
make ffmpeg's functions to immediately return so I can exit. Currently
my termination halts waiting for ffmpeg to return so I can join the thread.
