Answer 1

The changes I've made to your command line:

• I've specified the audio codec explicitely so it is AAC-LC.
• The addition of "-strict -2" to use the experimental AAC-LC codec.

This works for me in both Firefox and in Chrome.

ffmpeg -y -i "INPUT" -ar 22050 -ab 512 -b 800k -f mp4 -s 514*362 -strict -2 -c:a aac "OUTPUT.mp4"

I hope that helps, if so please mark this as good answer!
