git show 2473a45c85dce6872617b33fce396dbbd6347e8e avconv.c | patch ffmpeg.c
Original commit:
commit 2473a45c85dce6872617b33fce396dbbd6347e8e
Author: Janne Grunau <janne-libav@jannau.net>
Date: Wed Jan 18 10:53:41 2012 +0100
threads: change the default for threads back to 1
Using threaded decoding by default breaks backward compatibility if
AVHWAccel is used or if an appliction sets threadunsafe callbacks.
Avconv and avplay still use -threads auto if not specified.
