#42 Missing TV channel selection - Composite/S-video
Hi,
I am desperately missing the Composite and S-video Channel options in the KPlayer TV channel selection, as I am using external video source, rather than internal tuner (the card works fine, i can see the composite and s-video previews e.g. at Kopete as webcam sources).
Or is there any way to choose the S-video source in the current version of KPlayer?
Thanks in advance,
Radek.

Find the TV device in the multimedia library, right click it to open its properties, go to the Video page, and change the third option from the bottom, called Input. The default ("auto") is 0, so try setting it to 1 instead.
Please send me the contents of the message log, when playing with 0 and with 1 (or whatever the number for S-video). I can try and extract the available inputs and other things and put them in that option in the dialog and maybe even somewhere on the menu for easy access...
I don't have a TV card myself, so I'll need your help testing the changes.
Thanks!

Hi kiriuja, thanks for your quick tips:
I have tried to set the Input field to 1 (usually composite source) and 2 (S-video input, tested in mplayer) - now I can see a "slideshow" (ca 1-2fps, in comparison to full frame rate when running "mplayer tv:// -tv driver=v4l:input=2:width=720:height=576:brightness=10:contrast=-5:saturation=5 -vf lavcdeint")
Here is the KPlayer log:

Could You be so kind and try to explain me the "Video buffer shorter than 3 times audio frame duration. You will probably experience heavy framedrops." hint and help me to find some solution?
My current linux setup is far from perfect, I am just trying to cheat the live 200MB flash edition of Slax 6.02 (www.slax.org), in order to make it working with common TV cards out of the box (at least to watch TV flawlessly) - and kplayer seems to be a good base...
Thanks in advance,
Radek.

If you can make MPlayer play the stream from the command line, the best thing is to run
ps auxww | grep mplayer
while KPlayer is playing it, and compare with the MPlayer command line that works.
Also please post the output when you run MPlayer from the command line, to see the difference.
If at all possible, make XVideo or another accelerated output work. Plain X11 output is very slow.
