H264 480p videos won't play on my iPhone 3G

Hi Kyle,

Thanks for a great plugin! I only just found it a few weeks ago, I had no idea something as great as this existed for WordPress.
I am using the latest version of FFMPEG, 5th December 2013. The H264 and AAC all convert fine, and the OGG and WEBM if I need them.
I did get some stream errors earlier on some files while trying to convert, but seems ok for now.
My only question is, I make an HD version H264 and also a 480p version in H264 for mobile devices. It all works fine on all browsers and my HTC One droid, but when I checked with my old iPhone 3G, the videos don’t play on it. Possible they also don’t play on other iPhones.
I don’t have a newer iPhone, so I can’t check.
Since we have to keep the Apple lovers happy as they make up a load of viewers do you know the solution for this?. I am using the Video.js player, it just spins on the iPhone, only plays two videos I uploaded that were small in size to begin with, so I am thinking, maybe the javacode isn’t switching to the 480p version of the file, due to something conflicting. I also have qt-faststart enabled to fix the H264 streaming headers while encoding videos.

Here is the FFMPEG sample H.264 encode command:

/var/www/ffmpeg -y -i “http://www.jasondolan.co.uk/wp-content/plugins/video-embed-thumbnail-generator/images/sample-video-h264.mp4” -acodec libvo_aacenc -b:a 160k -s 640×360 -vcodec libx264 -profile:v baseline -pix_fmt yuv420p -level:v 30 -crf 23 -threads 0 “/var/www/wp-content/uploads/2013/12/sample-video-h264-480p.mp4”

Here is the FFMPEG test output::
