Re: [mythtv-users] Reliability problems when switching to view live tv
This turned out to be a known problem with pthreads in Debian based AMD64 systems. Unfortunately, it took a lot of time to figure that out.. Here is a link to an old mailing list entry describing the problem and a patch to fix it: http://lists.debian.org/debian-amd64/2005/03/msg00940.html On 7/16/05, Todd Ignasiak [EMAIL PROTECTED] wrote: Thanks for the response. I tried adding that line to my xorg.conf, but I still get the video problems. I can always open the ringbuf file with vlc. So, I know the data is there, and VLC can reliably open the video output. It seems like a communications problem between the frontend and backend.

When it works, it works great.. very impressive feature set. But, I have probably a 20% success rate in actually viewing live TV. Most of the time, I only get a blank screen and have to kill mythfrontend to get out of it. I restart the frontend and backend processes, and try it a few more times, eventually I will get lucky and I will get the live TV stream. When that happens, it usually works fine from then on, until I exit live viewing and try to go back again.. I think the card is providing data, as the ringbuffer file is growing, and I can even view the video in it with vlc or mplayer. Is this typical of other HDTV implementations?From what I hear, the DVB drivers for ATSC/QAM are relatively new, could it be related to the driver status (although, if that were the case, why would the backend still be getting data)? Any pointers are greatly appreciated. My limited experience is that the picture comes up every time, but, there is a delay while it locks in to the station. The only real problem I have is that sometimes there is no sound until I switch tracks (numpad +/-). A few other people in Australia have mentioned similar issues, and I think it's to do with the AC-3 sound. I haven't tried the very latest drivers from linuxtv.org. I tend to wait until they come out in an rpm. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
