| Post subject: | Realtime priority on R5.5 driving me nuts |
I'm trying to get smoother playback on my HDTV programs. I looked at the log from the frontend and noticed the message that tells me that my frontend is not setting realtime priority. My /etc/security/limits.conf file is set correctly. No soap. I tried even using the old deprecated chmod a+s method on mythfrontend and mythtv. No soap. Nothing I do allows the frontend to set realtime priority. What the heck is going on?!? -- Joe |

This may seem overly simplictic of me but is the option turned on in the settings. Under: Utilities/Setup -> Setup -> TV Settings -> Playback On the first screen there, the very first option is Enable realtime priority threads. I have just done a clean install yesterday of R5.5 and the box is already ticked on mine so I would be pretty sure it would be on for yourself already. Just a thought. |

Yep! Thanks for the reminder, anyway. From the Gentoo page I learned to check with Code: ulimit -r
This gives me back "50" which is the correct answer if everything is working correctly. Yet the frontend complains that it can't set realtime priority. I scanned the MythTv archive and it says the message applies to either SUID or setting priority through rlimits. Color me confused! -- Joe |

Does the mythtv user have sufficient privileges to use realtime priority? Sorry I can't provide more detail, but I've never bothered with this myself... |

Joe, just out of curiosity, why do you use real-time threads? I don't use them and I don't have any problems with hidef playback. Marc |

My log would spit out errors when I tried to enable real-time priority threads as the mythtv user. If I ran as root it would not show that. I could not tell a difference between the two, but have since realized that I did not have real-time priority threads enabled in R5. Maybe it is something else causing your choppiness? I only use standard def so I can't be of much help there... |
