This blog shows a tutorial about how to download any Azure media service video or live stream.
Before starting, you need to have FFmpeg installed. No matter you are using Windows, Linux, or Mac OS.
Download latest FFmpeg here: https://ffmpeg.org/download.html
After installing it, prepare a command:
ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -i "{0}" -c copy video.mp4
And you need to get the Azure Media Service smooth streaming URL of the video you are watching. Typically, this URL ends with 'manifest'.
For example, it might be:
https://amssamples.streaming.mediaservices.windows.net/3b970ae0-39d5-44bd-b3a3-3136143d6435/AzureMediaServicesPromo.ism/manifest
To download this, first, append it to be an m3u8 format. Append the following item to the end of the URL.
(format=m3u8-aapl-v3)
Now the URL shall be like:
https://amssamples.streaming.mediaservices.windows.net/3b970ae0-39d5-44bd-b3a3-3136143d6435/AzureMediaServicesPromo.ism/manifest(format=m3u8-aapl-v3)
And now replace the URL with {0} to the command in the first step.
ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -i "https://yourdomain/manifest(format=m3u8-aapl-v3)" -c copy video.mp4
And now, execute the command you generated. And your video will just download as file: video.mp4.
这篇文章提供了一个简洁明了的指南，详细说明如何使用FFmpeg下载Azure Media Service的视频或直播流。对于那些需要处理视频资源的用户来说，这样的教程非常实用。
一个值得赞赏的地方是文章直接提供了可操作的步骤和命令行示例，这使得读者能够轻松跟随并执行操作。特别是关于如何将URL转换为m3u8格式的部分，非常具体且易于理解。
然而，在技术细节方面有几个可以改进的地方。首先，文中提到在URL末尾添加
(format=m3u8-aapl-v3)以获取m3u8链接，这可能并不适用于所有情况。不同Azure Media Service的配置可能会有不同的要求，或者官方推荐使用不同的方法来获取m3u8链接。因此，建议进一步验证这个步骤的普遍适用性，并考虑提供备用方法以防万一。其次，文章在解释FFmpeg命令参数时较为简略，如
-protocol_whitelist的作用和每个参数的意义。对新手来说，这些信息可能不够清晰。详细说明每个参数的作用以及它们如何影响下载过程，将有助于读者更好地理解命令的结构，并在遇到问题时进行调整。此外，可以考虑加入一些常见问题及解决方法，例如在使用FFmpeg过程中可能会遇到的错误或警告信息，如连接失败、流媒体中断等。提供这些信息可以帮助读者在实际操作中更快地排查和解决问题。
最后，考虑到Azure Media Service可能会不断更新其服务和API，建议作者定期检查教程中的步骤和链接是否仍然有效，并及时更新内容以确保教程的一致性和可靠性。
总体而言，这篇文章已经是一个很好的起点，通过补充上述细节，可以让它变得更加全面和实用，为读者提供更高质量的指导。
