Display image in vlc output

Postby juraj » 28 Dec 2009 23:02

Hi,

is there any way how to display an image (or text on the fly) in vlc output. I would like to display a semitransparent image in video just like vlc does it with snapshot preview when snapshot is taken. Should I create a couple of new functions for that in libvlc or is already something there? Can OSD or marquee_option be any help for me? Actually I don't understand exactly what marquee is.

Thanks!
Juraj

I have the same problem, but still didn't find an appropriate solution.

I wish the libvlc had more documentation.

The marquee filter overlays text on the video, while logo filter adds, well, a logo.

Those are programmatically available only from LibVLC 1.1.

It would be great for my application to have a continuos video stream and overlay a semitrasparent image generated with alpha channel and containing some augmented reality information... would that be possible with the new API? when 1.1 will be aproximately available? possibly with some example or documentation about these new APIs?

The logo filter can only add an image from a file. This might be awkward if the overlaid content is dynamic.
