wmv 中的 h264 剪辑无法在 iPad 上的 HTML5 视频中工作（黑屏）

我需要使 .wmv 文件在 iPad 上的视频标签中播放。使用 Handbrake 我已经在 Chrome 中播放了视频，所以我知道我的语法没问题。我什至可以在 iPad 上播放另一个网站的 mp4，没有任何问题。

这是 ffmpeg 关于我的（不工作）流的说法：

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

这是 ffmpeg 关于他们（工作）流的说法：

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

这是我的标记： html = '' + '' + '

视频失败！

' '; $div.append(html);

我认为这是因为 wmv 于 2002 年首次编码导致了该问题，但我无法确定这一点。以下是 ffmpeg 关于 wmv 的说法：

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':

原文

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.
