Xml 如何播放使用MP4box加密的视频

我正在尝试播放一段我使用MP4box加密的视频，其中包含这些选项

mp4box-crypt test.xml 1.mp4-out clear.mp4

这是我的xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<GPACDRM type="CENC AES-CTR">
<!-- example for GPAC 'clear' DRM System - keys are listed after the content and UL follows -->
<DRMInfo type="pssh" version="1" cypherOffset="9" cypherKey="0x6770616363656E6364726D746F6F6C31" cypherIV="0x00000000000000000000000000000001">

</CrypTrack>
</GPACDRM>

但是，我怎么能在不解密的情况下播放它呢。 就用这个xml玩吧？

请帮助我，非常感谢。

这里是GPAC撰稿人。请注意，我们更希望您使用github问题

您的XML文件错误。您为DRM方案提供儿童“0x279926496a7f5d25da69f2b3b2799a7f”和“0x676CB88F302D1022799264949499885984045”。但是轨道加密的孩子们是不相关的

在您的案例中，正确的XML是：
