getting XvMC working and how to edit/encode

I got my card yesterday and after a couple hours of messing around I have it working. I have
a few questions though.

I have an Nvidia Geforce4 MX card and when I run configure on xine-hd, I see: "XvMC (Xvideo
*static*)". However, after compiling, when I run xine,I get this:

main: probing <xvmc> video output plugin
video_out_xvmc: XvMC init_class
video_out_xvmc: XvMC extension not present.

I also tried compiling mplayer with XvMC support, and it does not detect it. I have the
latest NVidia drivers running with Xfree 4.3. Anyone have any thoughts on why the XvMC
extentions are not working?

Second, I know I can capture a program by running "getatsc /dev/dtv > file". How to I
edit/encode that file after I am done? I would like to convert to DIVX (using mplayer) or
DVD format (using mjpegtools).

Thanks,
Bryan Opfer

I have the same setup as you and am running the nvidia driver 4496 from the nvidia web site. Xine has no problem with xvmc. The nv driver included with most releases doesn't do xvmc.

Are you sure your XF86Config references the right driver?
Does xdpyinfo confirm that xvmc is active?

Attached is the extension list from xdpyinfo that I get as well as the nvidia startup stuff from messages.

I got it working. I had TwinView enabled and when I disabled it, it worked. thanks for the xdpyinfo command. that was helpful.

Now I just have to figure out how to work with these captured files.

Well, I can't seem to get anything working right for encoding these files. The main problem seems to be converting the transport mpeg file that is created by getatsc into a program stream mpeg file. I have tried dvb-mplex and ts2ps on linux and tried HDTVtoMPEG2 on windows. None of them work properly on my ts files.

# dvb-mplex -t MPEG2 -o fb.ps fb.ts
Scanning video stream for a sequence header and pulldown type ...
no pulldown detected ...

Scanning video stream for pictures ...
Invalid MPEG2 Video stream, no picture coding extension present.
-------
ts2ps, always produces a 3kb file, no matter that PID's I use from tspids.
-------
HDTVtoMPEG2 doesn't recognize the ts file correctly, because it doesn't show me the channel info like it should. And no matter what ID's I use i get the 3kb file here too.

Anyone having any luck with these ts files? Any help would be appreciated.

One thing that I have descovered is that it is just the 1080i recordings that are not working for me. 480p ts files work fine in all those programs. Why would they be different?
