| Post subject: | R5.5 video freezes after 1 sec. and locks FE--workaround |
I've got a Dell Dimension 4700 with a p4 3.0 and integrated Intel graphics (not sure of the chipset offhand). This system was previously running MythTV .21 on Ubuntu, but I moved to R5.5 last night. Now, when I try to view LiveTV or a recording, the system will play <1 sec. and freeze. The problem happens with SD and HD content that played fine previously (on Ubuntu) so it's not a performance issue. If I start the FE from a shell and switch to the shell view while the FE is frozen, I see the following message repeating: "NVP: Timed out waiting for free video buffers" I looked that up and came across this page: http://www.mythtv.org/wiki/index.php/Troubleshooting:NVP:_Timed_out_waiting_for_free_video_buffers. I tried disabling GLX in the xorg.conf but that was no help since I'm already running QT. I also tried disabling the setting in FE>Setup>TV>Playback>"Enable real time priority threads" since the description says to try disabling this if video freeze occurs--but this didn't help either. What does work for now is to rename /dev/rtc--I got this idea from this page: http://www.mythtv.org/wiki/index.php/User:Cactus What I'm not sure about is why this problem is showing up now and if there is a better way to deal with the issue? I gather that MythTV uses the RTC to sync frame changes, but it looks like usleep could also be used: http://www.mythtv.org/wiki/index.php/Frame_display_timing. Does anyone know how to disable RTC use for video playback? Thanks. |

Hi, Did you ever work out a better solution to this? If not, does renaming /dev/rtc cause mythwelcome to stop working (automated wake up)? BigB. |
