playing gamecube on a computer monitor?

curious_bob

Is it possible? Are there RCA to VGA adapters? Or could you just run it through a video capture card or something?

I live in the colleg dorm and I'm trying to find ways to save space.

I asked the same question a few months ago, and here's what you can do:

Buy a cheap analog capture card (something like 20$), any of the bttv ones should do (no hardware encoder or anything like that).
then connect it to your Gamecube and start playing, the picture quality wont be as good as on a TV but it'll be playable.

I have a PVR card, so I can't do this since there is a ~2 second delay which makes playing any game nearly impossible.

emerge gcube ? not used it myself, but looks like a possible way forward.

curious_bob,
The quality is not too bad, I personally don't mind it, but some people are picky about picture quality..
If you get a regular capture card (not a PVR one) then you should be able to play with no problems speed-wise, and if you don't mind a slight degradation in image quality, then I'd say thats your best bet if you want to save on room space.

truekaiser,
From my understanding, the delay is not from Myth-tv but since the card (Hauppage PVR-150 MCE) has a hardware MPEG2 encoder, it takes it a second or so to encode the raw video into MPEG2, and thats where the delay comes from.
I saw a post on the Ivtv mailting list at some point about bypassing the hardware encoder and getting the raw Yuv stream, but I'm not sure if that works yet.

i have a 2 second delay trying to pay my ps2 on my hauppage mce 150. I was using mplayer to do this but I noticed it buffered the signal which is probably why there's a 2 second delay. What TV app would allow me to play without the delay? Would zapper work?

edit: i found this post in the mailing lists

saying that video32 is the raw yuv stream and with the right command and mplayer should have close to no delay

mplayer -demuxer rawvideo -rawvideo pal:format=hm12 /dev/video32

This is a little late but I figured I would post this in case anyone would want to know because I had to look hard for the answer:

I saw this on another site somewhere:

"Take a look at <myth-install-prefix>/share/mythtv/tvmenu.xml. Copy the
file to ${HOME}/.mythtv/tvmenu.xml and then edit it. There's an
example at the bottom of the file; try uncommenting it to get a
"Passthrough Mode" button in your TV menu."

So I went and did the following:

1) emerged xawtv
2) uncommented the button

Now i can use the recording feature with shows, or if I want to play a game I have a button that bypasses the encoder using xawtv, Thus removing the lag. I am using an old Hauppauge 61381 d423 card and it works perfectly in this setup for both recording and for games in real time. In fact I had thrown it in a box a long time ago because I could never get it to work in Windows, but then I saw mythtv and was able to get it to work fine. Go figure..
