    As title says, I don't have a problem doing a build (other than it takes forever to build, even on slow optimisation setting).

    But I do get this error when I run it in Firefox (v33.0.1):
    Unable to find type [UnityEngine.dll]UnityEngine.AssemblyIsEditorAssembly>


    What exactly is causing this error?

    It's a missing (stripped) type. It's a bug, but in fact harmless.

    (As for the compile speed, do a development build, with stripping enabled in the playersettings and set it to the highest optimization level).

    So in theory it should run fine? If in fact it doesn't run fine, it probably has to do with something else on my end?
    I currently get stuck on a white screen after the error pops up.

    Never mind.. it was an error on my end.. On my first scene I had an intro video using MovieTexture.
    I removed that scene from the build and now it works fine.

    Thanks for the compile speed tips.

    MovieTexture is indeed not available in Unity 5.0 WebGL.

    Just to make it clear:

    Development build checked with Optimisation Level - Slow (fast builds), right?
    And which Stripping Level: Strip Assemblies, Strip ByteCode or Use micro mscorlib?

    Strip ByteCode will give you engine stripping. IL2CPP always strips, but actual granular stripping of the engine is only done through that level.

    Hi there, I am having a similar problem with a project of mine regarding using MovieTexture with WEB GL, after reading this i understand that you cannot use MovieTexture in WEB GL, so what other alternatives can I use as i have a MovieTexture assigned to a plane and this project is an existing demo which we show to clients, but we want to have it available for all people who visit our website to see using WEB GL, there must be a way surely around this or another way for WEBGL to view a video on a plane, if anyone has an answer it would be great? Thanks :)

    Currently, your best bet would be to use a html5 video element and to display that on top of your canvas.

    We have no specific plans for video on WebGL yet. I expect that we will have a solution out of the box eventually, but not for 5.0. It would probably be possible to get the current MovieTexture to work in WebGL by decoding the video in JavaScript. However, a video element based solution would be so much more efficient and modern, that it adding MovieTexture support seems kind of backwards in comparison.

    Hi jonas, tanks for the useful heads up, i think we will definitely go down the video element side of things when we get our other main issues out the way. Were now having a problem when we run our build outside of our local domain, we keep getting the error which is 'uncaught exception: could not load memory initializer Data/UnityStuff.html.mem' we haven't had any experience with this error before and are struggling to find any examples as unity 5 hasnt even come out yet, if you have any idea as to why this may be we would love to know! Cheers

    It appears that it fails downloading the file Data/UnityStuff.html.mem from the web server. Did you upload it? One possible reason might be that we are incorrectly setting the file access permissions on the "Compressed" folder (which will be fixed in b14), so check those before uploading.

    also some servers (such as IIS) or webhosts with strict settings won't serve unknown extensions or mime types by default

    ive added it the .mem to mime types on our server, which has now got rid of the error, however now its not loading the content, the canvas just goes white?
