问题描述
我正在尝试使用ffmpeg获取苹果验证的http媒体流，并且收到错误。以下是一些错误示例：
I'm trying to get apple-validated http media streams using ffmpeg and am getting errors. Here are some error examples:

'audio / mpegurl'。

我已尝试过这些命令，其中包括：

如果有人能帮我弄清楚我应该运行什么ffmpeg命令，我会非常感谢！
If someone can help me figure out what ffmpeg commands I should be running I'd really appreciate it!
推荐答案
关于第一个警告：
警告：播放列表Content-Type是
'application / x-mpegurl'，但应该是
'application / vnd.apple.mpegurl'，
'audio / x-mpegurl'或'audio / mpegurl'。
WARNING: Playlist Content-Type is 'application/x-mpegurl', but should be one of 'application/vnd.apple.mpegurl', 'audio/x-mpegurl' or 'audio/mpegurl'.
它可以来自服务器设置。按照 Ion Cannon post ：
It could be from the server setup. Follow the instructions from Step 4 of this Ion Cannon post:
准备HTTP服务器上传一组
的文件，代表流和
a流定义文件（ts和
m3u8）。这些文件现在可以上传到
a网络服务器，但是
是另一个重要的步骤，即
确保他们正确地下载
，并且正在设置mime
类型。有两种mime类型，
对于流
内容很重要：
Prepare the HTTP server Upload a set of files that represent the stream and a stream definition file (ts and m3u8). Those files can be uploaded to a web server at this point but there is another important step to take that ensures they will be download correctly and that is setting up mime types. There are two mime types that are important for the streaming content:
.m3u8应用程序/ x-mpegURL
.m3u8 application/x-mpegURL
.ts video / MP2T
.ts video/MP2T
如果您使用Apache，您
想要将以下内容添加到
中httpd.conf文件：
If you are using Apache you would want to add the following to your httpd.conf file:
AddType应用程序/ x-mpegURL .m3u8
AddType application/x-mpegURL .m3u8
AddType video / MP2T .ts
AddType video/MP2T .ts
如果你是
使用lighttpd，你会想把
这在你的配置文件（如果
你有其他mime类型定义make
确定你只是添加这些，不要设置
他们）：
If you are using lighttpd you would want to put this in your configuration file (if you have other mime types defined make sure you just add these and don't set them):
mimetype.assign =（.m3u8=>
application / x-mpegURL，.ts=>
video / MP2T）
mimetype.assign = ( ".m3u8" => "application/x-mpegURL", ".ts" => "video/MP2T" )
