Sitecore 媒体库与 iOS 不兼容？

发布于 2024-11-17 21:50:51 字数 1461 浏览 3 评论 0原文

我在 iOS 设备上播放正确编码的视频时遇到问题。以下是一些背景/信息：

我们正在使用 jwPlayer 进行播放
视频通过 flash 和 HTML5 播放效果非常好
视频是通过 zencoder 的默认设置进行编码
我们正在从适用于 iOS 设备的同一服务器提供视频（但该网站不是 Sitecore）
通过 dropbox 同步时，视频在我的 iPad 上播放

通过一些调查和 Zencoder 优秀支持人员的帮助，我们认为问题可能与标题有关（顶部是不起作用的视频，底部工作正常）

：任何人有任何想法这个问题是否真的与标题相关？如果是这样，有没有办法让 sitecore 正确地为媒体提供服务？

编辑：另外，如果有什么区别的话，我们使用的是 IIS6。

编辑：特别麻烦的差异是：

传输编码（不起作用的那个是分块的）
内容长度（顶部视频中缺少）
内容类型（我认为这是一个大问题。我在 sitecore 中有正确的 mime 类型设置- 我不知道 Sitecore 不提供服务）

I am running into an issue playing a properly encoded video on an iOS device. Here is some background/information:

We are using jwPlayer for playback
The video plays great through flash and HTML5
The video was encoded through zencoder's default settings
We are serving video from the same server which works on iOS devices (but that site is not Sitecore)
The video plays on my iPad when synced through dropbox

Through some investigation and some help from the great support staff at Zencoder, we think the issue may be related to the headers (top is the video that does not work, bottom works fine):

Does anyone have any idea whether this issue is actually header related? If so, is there a way to get sitecore to serve the media properly?

Edit: Also, if it makes any difference at all, we are on IIS6.

Edit: The particularly troublesome differences are:

Transfer-Encoding (the one that is not working is chunked)
Content length (missing on the top video)
Content type (I think this is the big one. I have the proper mime type setup in sitecore - I don't what Sitecore is not serving it)

我在 SDN 上发布了一个类似的问题。这是关于让视频在 iPad 上播放并从媒体库。有用的响应是 Sitecore 媒体请求 HTTP 处理程序 (sitecore_media.ashx) 以块 (HTTP Transport, Transfer-Encoding: chunked) 形式提供媒体响应，这与Apple 协议（响应必须以一大块形式传递给客户端）。您可能想尝试看看是否可以覆盖 MediaRequestHandler。

我遇到了同样的问题，并且能够通过一些事情解决它：

我将 mime-type 添加到 MimeType.config，如下所示：
```
video/mp4
```
进入媒体库中的项目，并将该项目的 Mime 类型更改为“video/mp4”。< /p>
进入服务器，删除“C:\inetpub\wwwroot\Sitecore62\Website\App_Data\MediaCache”下的所有文件

我在 Curl 下有不同的标头值，但错误的 mime 类型与您的一致。一旦我完成了上述所有操作，mime 类型就正确返回并且视频播放了 - HTML如下：

<video class="video-js" width="640" height="360"  autoplay controls loop>
  <source src="http://<server>/~/media/client/videos/video.mp4" type="video/mp4" />
</video>

I ran into the same issue, and was able to get past it through a few things:

I added the mime-type to MimeType.config as below:

<mediaType extensions="mp4"><mimeType>video/mp4</mimeType></mediaType>

Went into the item in the Media Library, and changed the Mime Type of the Item to be "video/mp4".
Went into the server, and deleted all files under "C:\inetpub\wwwroot\Sitecore62\Website\App_Data\MediaCache"

I had different header values under Curl, but the wrong mime-type was consistent with yours. Once I did all of the above the mime-type was returned properly and the video played - HTML below:

<video class="video-js" width="640" height="360"  autoplay controls loop>
  <source src="http://<server>/~/media/client/videos/video.mp4" type="video/mp4" />
</video>
