Comment (by terran):
> ffmpeg -i rehearsal.mp4 -threads 4 -vcodec libx264 -b:v 7000000 -strict
experimental -acodec aac out.ts works fine?
It does work at the moment, as does the previous command with -threads 4,
but changing to -threads 0 causes the failure again. The behavior is non-
deterministic when -threads 4, but will always fail with -threads 0
apparently.
In other words, this fails too:
{{{
ffmpeg -i rehearsal.mp4 -threads 0 -vcodec libx264 -b:v 7000000 -strict
experimental -acodec aac out.ts
}}}
But this does not:
{{{
ffmpeg -i rehearsal.mp4 -threads 4 -vcodec libx264 -b:v 7000000 -strict
experimental -acodec aac out.ts
}}}
Also, I'm using 'git bisect' to narrow down the changelist that introduced
the problem. So far, I can say that it happened between sept 5 and sept
10. I'll provide more details on that when I narrow further.
