Add marquee to RTSP stream

[Klamay]

Hi experts!

I'm using libVlcSharp to stream video in RTSP mode.
I'm trying to add a marquee on-the-fly, but I fail.

What I'm doing is something like this:

Code: Select all

Core.Initialize(); var vlc = new LibVLC (); var mediaPlayer = new LibVLCSharp.Shared.MediaPlayer(vlc); Media media = new Media(vlc, @"test.mov"); media.AddOption(":sub-source=marq{marquee=TEST,position=5,color=0xFFFF00,size=50}"); media.AddOption(":sout=#rtp{sdp=rtsp://127.0.0.1:555/test.sdp}"); mediaPlayer.Play(media);

Video is correctly streamed, but the marquee is not shown.

I also tried this way:

Code: Select all

mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Enable, 1); //enable marquee option mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Size, 50); //set the font size mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Position, 5); //set the position of text mediaPlayer.SetMarqueeInt(VideoMarqueeOption.X, 10); // margin X mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Y, 10); // margin Y mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Color, 16711680); // Color mediaPlayer.SetMarqueeInt(VideoMarqueeOption.Opacity, 250); // Opacity mediaPlayer.SetMarqueeString(VideoMarqueeOption.Text, "TEST"); //text mediaPlayer.Play(media);

Nope. The video is there but without marquee.

Does anyone know how to make it work?

Thanks!

If you don't transcode, that's just useless options for display

Thanks for pointing out that I need to transcode.

So, I try to add the marquee on the client side, where I already transcode the stream.
So something like:

Code: Select all

Core.Initialize(); var vlc = new LibVLC (); var mediaPlayer = new LibVLCSharp.Shared.MediaPlayer(vlc); var media = new Media(_libVLC, @"rtsp://127.0.0.1:555/test.sdp", FromType.FromLocation, ":sout=#transcode{vcodec=h264,vb=6000,acodec=mp4a,aenc=fdkaac,ab=128}:file{dst=test.mp4"}", ":sout-keep"); media.AddOption(":sub-source=marq{marquee=TEST,position=5,color=0xFFFF00,size=50}"); mediaPlayer.Play(media);

Still, I get the transcoded file but I don't see any marquee :/

Any idea?

Thanks!
