h264 clips from wmv's not working in HTML5 video on iPad (black screen)

I need to make .wmv files play in the video tag on iPad. Using Handbrake I've gotten videos to play in Chrome, so I know my syntax is fine. I've even got another website's mp4 to play on the iPad with no problems.

This is what ffmpeg says about my (not working) stream:

Stream #0.0(und): Video: h264 (Main), yuv420p, 320x238 [PAR 1:1 DAR 160:119], 32 kb/s, 28.77 fps, 90k tbr, 90k tbn, 180k tbc

This is what ffmpeg says about their (working) stream:

Stream #0.0(und): Video: h264 (Main), yuv420p, 1280x544 [PAR 1:1 DAR 40:17], 1677 kb/s, 24.99 fps, 50 tbr, 90k tbn, 50 tbc

Here is my markup: html = '' + '' + '

video fail!

' '; $div.append(html);

I this that because the wmv's were first encoded in 2002 is causing the issue, but I have no way of being sure of that. Here is what ffmpeg says about the wmv:

Seems stream 1 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, asf, from 'pattySlotFormation.wmv':

I haven't figured out why this is happening, but I've found 2 solutions.

Upload the videos to youtube and embed them on your webpage. Upload the videos to youtube and then download them as an mp4. That file will work on iPad.
