[FFmpeg-user] Windows Media Player cannot play the file

Hello:


       I'm getting "Windows Media Player cannot play the file. ...".


       This is the result of "ffmpeg -y -r 2 -i tst%d.png -b 300k 
tst.mp4" with the attached .png files.  This command produced attached 
tst.mp4.  Unfortunately, it didn't play.


        Any suggestions for how to get past this would be greatly 
appreciated.


        Also, I'd be pleased to hear comments on what might be the most 
generally useable output formats, etc.  I'm hoping to distribute 
material via YouTube and other outlets, and I'd like to minimize 
compatibility problems that viewers might have.


       Thanks,
       Spencer


p.s.  I tried to include a "print screen" image but got a message saying 
it was too big.  I'm happy to provide it upon request.
