The VideoLAN Forums

Hi there,

I am trying to add a logo in VLC to overlay onto the video output. I have used the inbuilt module for this which works fine but I just realised that it seems to do pixel per pixel which means that if I have a 200x200 logo which looks good on a 1080p then it will look at lot bigger on a 720p video.

Is there a way to automatically scale the logo so that it appears to be the same size regardless of the video sources resolution?

One work around would be to upscale all the videos on the fly to 1080p, but I cant seem to find a option to do this? The canvas option seems roughly what I need but I cant get it to work and googling it only gives me results regarding streaming video, I just want to transcode the files on the fly to 1080p, add the logo and play it locally on my PC.

Any ideas?

Please try VLC 1.2 for this.

Hey, thanks for the tip. I have installed VLC 1.2.0-git (OSX Intel 32bit version). The logo is not scaling though and I can't see any option under Preference to turn such a feature on. Is there some new parameter or something I need to enable?

Edit: Not sure if this is related but I am getting a lot of "main subpicture warning: original picture size is undefined" logged if I start VLC using -vvv
