Playing Camtasia Video In Web Browser Control

[cmmorris1]

Hey guys,

I have tried to play a Camtasia video inside a web browser control but it comes up with javascript needs to be enabled error on page. How can I work it or find a work around that? I'd like to have a listbox that contains the movies and they would play in the browser. I have a membership site that I'd like to have a player that authenticates the user before playing them but first things first, what is the best way to accomplish playing Camtasia videos inside a form?

One question, how are Camtasia videos different from other videos?
Why can't you just add a Windows Media Player control to your form and play it there?

[cmmorris1]

Well outside of the html page their played on it depends on how they're produced. It could be a flv or swf file or even mp4. So it depends on how it's been rendered.

[Zeelia]

Okay.
So;
1. If you want to show your video on a HTML page, just simply navigate the webbrowser to the HTML page and then let the page to the rest. As for what code the HTML page should have, I can't help you without seeing the Camtasia Video code but you can try <object> or the "unofficial" <embed> tag.

2. If you want to play the video directly through your application without webbrowser, you would need to check which format the video is. Swf needs flash player. As for the other formats, you could use VLC Control (you get this when installing VLC).

[cmmorris1]

Yeah, I think VLC would play all formats. Can you give me some sample code example to look at for using the VLC player?

[Zeelia]

Well, start by adding the VLC control to your form (Right click your toolbox and Choose Items... Look around for VLC, it should be under COM).

The rest is pretty selfexplaining.

[cmmorris1]

Thanks, will give it a go.

[Zeelia]

Good luck ^.^

So far the code I've seen example of isn't working, here is what I'm seeing:

AxVLCPlugin21.playlist.add(OpenFileDialog1.FileName)
AxVLCPlugin21.playlist.play()

[Zeelia]

Okay. I'm just gonna open a new project...
Add the VLC Plugin to my toolbox...
xD Be patient, I'm currently running on a 512 MB RAM...

Try the BaseURL property,
VLC.BaseURL = "C:\Myvideo.avi"

[cmmorris1]

I'm getting "VLC is not declared"

[Zeelia]

Well yeah, thats cuz your control is named
AxVLCPlugin21
I renamed my control to VLC since its much easier to write.

Alright, this code worked for me:
VLC.playlist.add("Male1.wmv", 0)
VLC.playlist.play()

Or as it may be to you xD

AxVLCPlugin21.playlist.add("Male1.wmv", 0)
AxVLCPlugin21.playlist.play()

Here is the error I'm getting:

Do you get that error from debugging?

[cmmorris1]

I tried to run the project and got the message.

[Zeelia]

okay, try deleting the VLC Object and adding it again, I just created a project with a VLC object and played a video without problems...

[cmmorris1]

I've tried it 3 times. Doesn't matter. I've got to be doing something wrong here?

I'm adding VideoLAN VLC ActiveX Plugin v1 and VideoLAN VLC ActiveX Plugin v2.
Tried both, not working for some reason.

[Zeelia]

ok, I think some corrupt code has destroyed the Form, that happens sometimes when using 3rd party plugins.
You can start a new project or delete the form itself which contains the VLC plugin and redo it, there must be something wrong in Form1.Desinger.vb

[cmmorris1]

Yeah, I've tried it on different forms. I'm still looking into it though.

[Zeelia]

I can create a project and send it to you... hold on a sec

[cmmorris1]

k...got to put my daughter to sleep...will check on this in a bit.

[Zeelia]

Alright! Sorry it took so long time but here you have it, a fully working VLC media player.

[cmmorris1]

Still getting same error result. Thanks though for that.

[Zeelia]

Hmm.. I don't think this issue is related with VLC... it might be some hardware change affecting the system... As the long error says, there are missing classes ;S
Try on another PC and I'm sure it'll work ^.^

[cmmorris1]

I'll have to wait until tomorrow or the day after Christmas...this is weird. Thanks though for your help so far...I appreciate it!
