Colours Messed Up When Streaming Video

Postby perfectmark » 04 Jan 2004 14:59

I am streaming TV from my WinTV card (PAL) to the other computers on my network. But the colours are all messed up, if I adjust the Hue on the client machines, the colours look a lot better, but not perfect. Does anyone know how to solve this.

My Server uses Windows 2000pro, the clients are a mixture of Mac OS X and Windows 2000pro. I am using VLC 0.7 on all machines and streaming using MEPG TS Encapsulation, with MPV4 video and MPGA Audio.

And if you don't stream but watch directly? how are the colors then?
Don't use PMs for support questions.

The colours are fine if I just watch the TV directly.

I have the same problem, with my TV Card HAUPPAUGE WinTv Primio. If I watch directly the TV, it's all OK! But if I select VIDEO COMPRESSION, to save the stream or to transfer it to my notebook, the colours aren't correct. Instead, if i make the same thing from DVD Source or a MPG file also the video compression is OK!

I am using Windows XP Pro and VLC 0.7 on all machines and streaming using MEPG TS Encapsulation, with MPV4 video and MPGA Audio.

Have a look at the logs in the "Messages" window (needs to be opened before playing). You should find a list of formats supported by your input card. Have a look at the different "chromas" it supports and try to force them in the dshow section of the preferences panel.

Could you also paste the full log messages here ?

Great!

Could you still paste a full log here (for the default chroma) so I can fix the problem ?

____________________________________________________

Then, setting in the preferences panel, modules/access/dshow/

Resolution = 320x240
Chroma = RV32

now all is OK when I select video compression, but in direct stream I have the same problem that happended before with compression. It isn't a problem, if I want watch TV directly It's sufficient setting the default parameters.
