How to generate your own video file?
This video player cannot play every video file format. Actually, it only supports one: MJPEG. But don’t worry, it’s pretty easy to convert any video to this format on your computer using the excellent ffmpeg.
Assuming you have a input.mp4 file you would like to convert, here is the command you would need to use:
ffmpeg -i input.mp4 \
-vf scale=320:240,setsar=1:1,fps=15 \ # Resize video to [email protected]
-t 00:00:10 \ # Only keep the first ten second
-vcodec mjpeg \ # Use the MJPEG codec
output.mjpeg
This command will convert your input.mp4 file into a output.mjpeg one. Then you can simply uplad the playa.nwa along with the output.mjpeg video from NumWorks’ installer.
