我在上传视频时遇到了同样的问题。对于云视频，正在上传，但是对于手机内存中的视频却遇到错误。您要做的所有事情（而不是网址路径）都将NSData用于非云视频。希望这会有所帮助。谢谢。

   [[PHImageManager defaultManager] requestAVAssetForVideo:selectedImage
                                                            options:options
                                                      resultHandler:

Answer 2

我认为您需要在应用中请求权限才能加载视频。

尝试在info.plist文件中添加以下内容：

<key>NSCameraUsageDescription</key>
<string>Description why you need the permission</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Description why you need the permission</string>

也许这会有效。

Answer 3

在上传视频/图片之前，需要检查几点。

1您必须在info.plist中定义权限。

使用requestPlayerItem函数中获取的url创建数据并将此数据作为参数传递给uploadVideo函数。我希望这对你有用。

我无法将视频上传到服务器
