Hello,
can anybody please tell me that how can I change the default frame size, if I use [video=youtube]. I know many people will tell that to directly use the youtube embed tag so that I can change the frame size. But the problem is, my forum is also accessible from Tapatalk. So if I use embed tag, Tapatlk is show that just as an HTML. That is why I have to use mycode [video=youtube]. But after including the video, The frame size is comming very small respective to my forum width. That is why I want to change this. I also seen that if I use [video=youtube] the fullscreen button on that video player is not working. User must have visit the youtube site to see it in fullscreen mode. I want to change this too.

So please help as soon as possible.

ACP -> Templates and styles -> <your forum theme templates -> Ungrouped templates -> video_youtube_embed and change width and height values.

thanks

thanks alot for this
