Encoding a readable movie by QuickTime using FFMPEG

Question

I'm trying to encode an image sequence using the following command:

ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4 

However, QuickTime failed to open this file or sometimes play a black movie, while this movie plays great in VLC player. Any suggestions how to make it play well in QuickTime?

Here is the output:

Answer 1

Try to change the pixel format: -pix_fmt yuv420p

Answer 2

I was also making a video using a sequence of png files as input. What I found out is that Quicktime Player 7 will play my mp4 files just fine at any frame rate. Quicktime Player 10 will display a green window with some blockiness if the rate "-r" value is under 9. I can still have an input rate that is below the played rate by specifying the values like this:

ffmpeg -r inputRate -i %d.png -qscale 1 -r 9 output.mp4 

Note: I used ffmpeg 0.5.
