it seems ffmpeg had hardcode starting from 1.
you could modify source code file 'libavformat/dashenc.c’ in function
dash_init, member ‘segment_index' of OutputStream.
i’m not sure which unexpected result would be raised up.

Hi,
Thanks very much! After I upgrade SDL2 version 2.0.9, every thing is fine.

I am trying to use ffplay to play a video on my macOS.
What I see was a black screen, no matter what file I try.
When I drag the playing window to another screen (not the main screen), it’s ok.
When I drag it back, it turns black again.
I had try the master branch, but the problem is still.
