Answer 1

I think the issue with your encoding is not FFMPEG or HTML5. It's in the command and libraries that you are using. You should use the "libx264" library to encode MP4 videos for HTML5.

The proper command to use should be.

ffmpeg -i input.mov \
-acodec libfaac -ab 96k \
-vcodec libx264 -vpre slower -vpre main \
-level 21 -refs 2 -b 345k -bt 345k \
-threads 0 -s 640x360 output.mp4

For copy-paste convenience

ffmpeg -i input.mov -acodec libfaac -ab 96k -vcodec libx264 -vpre slower -vpre main -level 21 -refs 2 -b 345k -bt 345k -threads 0 -s 640x360 output.mp4

If you happen to stumble upon missing the x264 codecs, you may install the Zeranoe builds. Refer to this SO page. [ FFmpeg installation for x264 codec ]
