问题描述
当试图上传，转换/ EN code和prepare在Azure的媒体服务一个名为.3gp视频文件，我们得到了不支持的误差文件类型或codeC。 基于此信息，3GP应该支持导入。如何正确导入3GP并将其转换成MP4？
下面就是我们的内部日志说：

您应该看看<一个href=\"http://azure.microsoft.com/en-us/documentation/articles/media-services-azure-media-en$c$cr-formats/\"相对=nofollow>天青媒体恩codeR格式和codeCS 的，而不是微软前pression恩codeR支持的文件格式。
以上文档指出 .3GPP 和 .3GPP2 也能支持的文件格式。而视频codeCS是非常有限的： H.264 ， MPEG-1 ， MPEG-2 ， MPEG-4 ， VC-1 ， Windows Media视频， DV 。
根据 3GPP 这里 。如此看来，该文件格式本身支持多种视频和音频codeCS。只有少数人支持在Azure媒体恩$ C $铬。请使用一些第三方工具（如）仔细检查音频和视频codeCS 你的 3GP 文件，并确保它们在湛蓝的媒体连接codeR支持列表中。并注意文件扩展名没有定义文件中使用EN code媒体codeC。
When attempting to upload, convert/encode and prepare a .3gp video file in Azure Media Services, we get the error File type or codec not supported. Based on this information, 3gp should be supported for import. How do I properly import 3gp and convert it to MP4?
Here's what our internal logs say:

You shall look at Azure Media Encoder formats and codecs, but not the Microsoft Expression Encoder supported file formats.
The above documentation states that .3GPP and .3GPP2 are supported as file formats. And the Video codecs are very limited: H.264, MPEG-1, MPEG-2, MPEG-4, VC-1, Windows Media Video, DV.
Based on 3GPP data here. It seems that the file format itself supports multiple video and audio codecs. Only few of them are supported on Azure Media Encoder. Please use some 3rd party tool (like VLC) to double check the Audio and Video codecs of your 3GP file and make sure they are in the list of supported by Azure Media Encoder. And note that file extension does not define the codec used to encode the media within that file.
