Bug description: I have an really annoying flickering problem. In MythTV, pressing skip ahead causes my screen to flicker for about 5-7 seconds after which time it settles back to a solid image. This happens about 40% of the time I press skip ahead. I have taken a video at 60fps of the problem with my Canon IXUS 50: http://members.iinet.net.au/~mikewright/TopGear_Flicker.avi (about 13Mb) I don't think this is an XV-only issue, since killing MythTV during the flicker reveals the whole X desktop flickering then settling soon after. I am running: - Ubuntu Jaunty - MythTV 0.21-fixes using XV overlay. - 1280x720@50Hz - I'm using Yadif de-interlacer. System environment: -- chipset: G35 -- system architecture: 32-bit -- xf86-video-intel: 2.6.3 -- xserver: 1.6.0 -- mesa: standard -- libdrm: 2.4.0 -- kernel: 2.6.28-15-generic -- Linux distribution: Ubuntu Jaunty -- Machine or mobo model: Asus P5E-VM -- Display connector: HDMI Reproducing steps: Skip head by 30 seconds using remote or keyboard in MythTV.
We had bugs in the kernel-driver component that led to FIFO underruns, (which manifested as annoying full-screen flickering). I recommend you upgrade to a more recent kernel (such as 2.6.32) and please let us know if the problem persists, (and please clear the NEEDINFO keyword when you reply). Thanks, -Carl
Timeout. Could be a fifo underrun, but unless it can be reproduced on the current KMS + kernel overlay stack (where there has been a number of underrun bugs fixed, introduced, and fixed again), there is no point investigating. However, as I am looking at kernel overlay bugs atm I will keep an eye out for this issue.
