Description

I have the same question as this post:
videojs/videojs-contrib-hls#776

I want to control the key file request by php server script that only the valid user can get the AES key file. so I can not set cache expires of the key file.Therefor the php server been to very hevy. I had tried to modify mediaSegmentRequest function for check key.resovledUri and store the key value,but failed.
Is there any other way to fixed the proplem?
Thanks a lot!

videojs-contrib-hls version

videojs-contrib-hls 5.5.3

videojs version

video.js 5.19

Hey @riubin , why is it that the cache expires can't be set by the server?

[riubin]

Because the php server need check the session info by valid user that can watch the video. whatever, whether or not set cache expires the php server will be very hevy,but I do not want waste the resource of server. I think any others should have the problems too.
Thank you~

Add: The key file will be send to client by php script.client can't get key file directly.

Hey @riubin , the problem with caching the key requests by the player is if the keys do expire, the player has no way of knowing to fetch it again from the server. That's why the cache expires header is useful, and the caching can be done outside of the player.

I found @benvirus had fixed this problem by check key uri and store the key: https://github.com/videojs/videojs-contrib-hls/pull/865/files/87304c6c544d8eecd7de90acdd1685e7ee75a998..d308332bb58c6734aa6a3bc15a9a4a836997faa8
but in newer version it's not working anymore.My hls segments encypt with one key file,so the key uri is the same at all.can you add a option like "StoreKey:true",that will be good news for someone like me.

[benvirus]

You can fork the repo, add the cache key feature like me.

We'll review videojs/videojs-contrib-hls#1433 and add this feature to the project

Seems related to #140

While we believe appropriate cache-control headers are the optimal solution, we've added an option to not re-request the key on every segment (#446). It is out in version 1.10.0.

Just add this to your options and it will be cached. I was suffering from the same issue with latest build, and finally figured it out

html5: {
    vhs: {
      cacheEncryptionKeys: true
    }
  }

notice the vhs, not hls :)
