Citrix HDX redirection
HDX passes the job of rendering HDX-supported video (e.g. Flash video) to the local Citrix terminal, thus taking pressure off our Citrix servers.
The user does not notice anything different, e.g. a YouTube video appears to be playing in the YouTube website window but in fact it's being rendered locally and positioned onscreen as an overlay where the user would expect to see the video. (YouTube uses Flash instead of HTML5 for HDX video playback).
Using HDX allows Citrix users to watch HD videos with no lag or stutter. Unfortunately MS Stream videos do not appear to support HDX and therefore playback is extremely slow and glitchy, with stuttering audio and video, and a massive hit on the Citrix server's CPU.
MicrosoftStream uses HTML 5 Video playback where possible. We only fall back to Flash when the OS/Browser doesn't support our encrypted video playback via HTML5 + MSE. So for Win 7 or older + IE, Stream would play via Flash. For Win 8.1 or newer + IE or on any OS with latest version of Chrome/FF/Opera/Edge we will not use flash and instead use HTML5 + MSE video playback.
I'm still not clear on how we'd address this with Citrix HDX. Is it possible there is just some configuration on your company's Citrix that needs to be done to allow our video playback from Stream to use HDX? Are there changes on Citrix's code base that would need to be changed to support HTML5 + MSE playback that Stream does? Or if there is something we need to do in Stream's code base to support this.
If you want to discuss this further send me a private message. Maybe we could have a short call? I'm guessing we'd need folks from your organization that own/configure Citrix, someone from Citrix directly, and us from Stream.
Hi, it's probably best if you contact Citrix Support and try to make Stream a 'Citrix Ready' platform.
