Play a video

[yodasvideoarcade]

Is there a way to show (play / stream) a video file on screen in desktop target? (mac)

Really nothing?

I'd like to ask this again. Maybe I'm too stupid to see a simple way here. Please help me out. How to play/show a video file in Cerberus?

There is no simple way. For Cerberus to play a video file, a custom module would have to be written to use OpenGL and a video codedec.

 

[yodasvideoarcade]

Oh, ok. And no one has done that yet? No one is using video-cutscenes in their games?

There's at least a video module for HTML5 already made, maybe this can be useful to you.

Video Module

So, I've got video to work on html5. The module is here: https://github.com/zomagic/cerberus_magic/tree/master/video/modules_ext/magic Hope for someone to extend it for android :). That would be awesome.

Ages ago I did this on BlitzMax, using MCI calls and FindWindow/SetWindowParent API. Used to work well until windows 8 - but I tried running it right before posting this on Windows 10 and it failed on fullscreen (worked on windowed mode though).

I have no clue how to do it on Macs, but on Windows playing video inside OpenGL was always a mess. Maybe under Direct-X was easier, having DirectShow - but I never used it and I don't even know if thats still supported :/

Edit: Wow, it actually works, just not on the default DX7 driver of Blitzmax. Using OpenGL or DX9 the video plays just fine

Nice, do you think it would work for Cerberus-x too?

 

[SLotman]

In theory it should, yes. Just a small C file making MCI calls. But it would only work on windows/desktop target.

I did some tests on windows with a C library called PL_MPEG that can deal with mpeg1 videos. So far it looks promising at least on Windows.

Nice. Care to share some sourcecode? I would really love to see how to code Cerberus-x extensions in Windows.
Did you use Visual Studio some other package/compiler?

Care to share some sourcecode?

Sure, it's just not ready yet and really ugly. So that's my approach oftentimes. Get it to a working state and then think about the structure. 😝
I am using the gcc compiler as it is configured with Cerberus and see how far I get with just wrapping some of the native functions.
If I am unsure how the api works I build the example codes as described on their github page and modify it to see what is going on.
There are some things with coupling native code to cerberus that I figure out by just looking at the transpiled code. My plan is to make a tutorial or at least a list of some useful tidbits I am using.

That sounds promising! I was about to make some tutorial how to make HTML5 extensions but it takes some time. I was loosing time rying to make Cerberus access fileaccess system so I started to look around for other packages but noone seemed as nice as Cerberus so then I thought..let's try to mix and make extensions.

HTML5 is the easiest to make stuff for. For example, I have a small routine to get the browser language:

#If TARGET="html5"

    Extern
        Function getLanguage:String() = "function (){ return navigator.userLanguage || navigator.language; }"
    Public

#End

That's it! You can now use "getLanguage" and it will return the language string from the browser
