ffmpeg：ffplay 阅读音频直播 stream 来自 azure 媒体服务但没有声音
[英]ffmpeg: ffplay reading audio live stream from azure media services but no sound
问题描述
I also would say that playing audio file with the same command works fine, but with live streams it's kind of random.
我还要说的是，使用相同的命令播放音频文件效果很好，但对于实时流，它有点随机。
this is the output:这是 output：

Could be a failure in the DASH player support for CMAF in the FFMPEG library.可能是 FFMPEG 库中 DASH 播放器对 CMAF 的支持失败。
Have you already tried this with multiple web player frameworks like Shaka, HLS.js, video.js, iOS player in Safari and others with success?您是否已经使用多个 web 播放器框架（如 Shaka、HLS.js、video.js、Safari 中的 iOS 播放器和其他成功播放器）尝试过此操作？
Try here first - http://ampdemo.azureedge.net/ Or try a simple StackBlitz project with Shaka player first - https://stackblitz.com/edit/js-cwovc5?file=index.js首先在此处尝试 - http://ampdemo.azureedge.net/或者首先尝试使用 Shaka 播放器的简单 StackBlitz 项目 - https://stackblitz.com/edit/js-cwovc5?file=index.js
If your audio is working fine in both those browser players, its likely just an FFPlay issue with DASH CMAF.如果您的音频在这两个浏览器播放器中都运行良好，则可能只是 DASH CMAF 的 FFPlay 问题。
Try switching to HLS instead in FFPlay - output.ism/manifest(format=m3u8-cmaf)尝试在 FFPlay 中切换到 HLS - output.ism/manifest(format=m3u8-cmaf)
Or switch to HLS v3 output.ism/manifest(format=m3u8-aapl-v3)或者切换到 HLS v3 output.ism/manifest(format=m3u8-aapl-v3)
UPDATE: From my quick testing, it looks like FFPlay does not like to play back DASH with CMAF.更新：从我的快速测试来看，FFPlay 似乎不喜欢用 CMAF 播放 DASH。 It seems to work fine for me with HLS though.不过，使用 HLS 似乎对我来说效果很好。
I tested our HLS with CMAF - /manifest(format=m3u8-cmaf) and it worked fine.我用 CMAF - /manifest(format=m3u8-cmaf) 测试了我们的 HLS，它运行良好。
When I tried it with /manifest(format=mpd-time-cmaf) it just dies on me.当我用 /manifest(format=mpd-time-cmaf) 尝试它时，它就死了。 So, it appears to be a lack of support in FFPlay.exe for DASH with CMAF and time based indexing.因此，FFPlay.exe 似乎缺少对带有 CMAF 和基于时间的索引的 DASH 的支持。
