I am trying to upgrade my mythtv box to the latest 2.6.22 kernel and latest ivtv drivers and latest myth. But I'm having a little trouble with the ivtv_fb driver...
Here is what I've got running now. --> ivtv drivers from the 2.6.22 kernel. ( these load without errors and look to be working ok ) --> ivtv-fb compiled from the 1.0.2 tar ball -- ( NOTE: I did have to manually copy the correct ivtv-driver2.h to ivtv-driver.h because it wouldn't load when it used the ivtv-driver1.h -- I think this has something to do with the way detection of the 2.6.22 kernel is done. I'm running GENTOO BTW.) But the frame buffer loads now without errors --> IVTV X driver compiled from source downloaded from subversion X and mythfront end run great over the frame buffer, but playback using the PVR-350 decoder doesn't work.. Trying to troubleshoot the problem -- I went back to the command prompt and played the video using cat file.mpg > /dev/video16 This works great before I load the ivtv-fb driver, BUT once I load the ivtv-fb driver ( with modules.conf: options ivtv_fb osd_compat=1 ) The playback gives me a just a black screen -- although I can hear the audio... So I think the problem is the ivtv-fb driver... -- Am I testing this properly?? Or am I missing some command that needs to be run to tell the fb to switch from showing the X content to allow the video to be played?? This all worked under earlier kernel and older ivtv versions ( actually I think I was using ivtvdev driver not the X ivtv driver... ) I saw some people saying Xv with ivtv would allow playback over the ivtv frame buffer without using the PVR-350 decoder, but I don't know how to get Xv working with the ivtv-fb. If anyone can explain that I'll give that a try, but when I tried running myth playback without the 350 decoder to the ivtv X driver the video is very very choppy.. Maybe Xv would help that, but the way I had it working before with the HW decoding was so nice I'd really rather get that working. DMESG OUTPUT looks clean to me.. ----------------------------------------------------- ivtv0-fb: === Display mode change === ivtv0-fb: Display size 720x480 (720x480 Virtual) @ 32bpp ivtv0-fb: Display position 1,1 ivtv0-fb: Display filter : on ivtv0-fb: Color space : RGB ivtv0-fb: Running in compatibility mode.
