Comment (by ubitux):

 Indeed, thanks for tracking down the origin of the issue. I relayed the
 issue to Anton, he might come up with a better solution than reverting the

 On the other hand, reverting it doesn't solve the second error I mentioned
 (with -ss as input option):

 [avi @ 0x2858fe0] Application provided invalid, non monotonically
 increasing dts to muxer in stream 1: -14 >= -14
 av_interleaved_write_frame(): Invalid argument

 Also, it doesn't solve a similar issue with I have with a random MKV:

 Playback is out of sync again after something like:

 ./ffmpeg -i ppd.mkv -ss 150 -c copy -y out.mkv
