The ffmpeg command will default produce one that can only be decoded on Chrome. You should specify a codec supported by most browsers (`-c:v libx264`).

Thank you very much for posting that. I've been trying to figure out how to do that for a while.

I've also learned that -pix_fmt yuv420p is necessary, changes the colorspace from RGB to YUV

If ffmpeg has been built with libx264 support, than this is the default encoder for mp4 video.
