#10442: MythFrontend jittery video playboack on 2010 Mac mini
------------------------------+-----------------------------------------
Reporter: joenyland@… | Type: Bug Report - General
Status: new | Priority: minor
Milestone: unknown | Component: MythTV - Video Playback
Version: 0.24.2 | Severity: medium
Keywords: mac frontend | Ticket locked: 0
------------------------------+-----------------------------------------
I have posted this to the mythtv-users mailing list, but unfortunately no-
one has been able to offer any advice, other than installing Ubuntu on the
Mac mini, which isn't a solution.
Basically, 95% of the channels and recordings I watch (both live TV and
recordings) have jittery playback - no pixelation, but motion is not
fluid. This makes 95% of the stuff I watch/record in MythTV unwatchable on
my Mac mini, which is my main frontend system.
I am able to play back the same recordings files on the same system in
XBMC (via MythTV's UPNP), VLC (again, via UPNP) and on other frontends
too, without any issues.
There seems to be some issue with MythTV's ability to utilise the GPU on
my model of Mac mini, where other applications can utilise it fine. I can
play back 1080p content with all the bells and whistles in the likes of
XBMC, etc. so the GPU is definitely capable of what I am giving it.
Primary frontend
Mac mini (Mid 2010)
Core 2 Duo 2.4 GHz CPU
4GB RAM 1067 MHz DDR3
NVIDIA GeForce 320M 256MB GPU
OS X Lion (10.7.3)
MythFrontend jyavenard/backports/fixes/0.24 [v0.24.2-216-g247c4f1-dirty]
Backend
Dell PowerEdge T110II
Xeon E31230 3.2 GHz (Quad core +HT) CPU - 4 cores assigned to MythTV
backend server
1GB RAM 1333MHz DDR3 assigned to MythTV backend server
Recordings stored on 3 1TB Seagate drives in md RAID5
Ubuntu 10.04 LTS x64
MythBackend fixes/0.24 [v0.24.2-19-g02dd6ee]
HDHomeRun HDHR3 as the TV source - UK Freeview, so SD quality
I should be able to post a sample clip later on, as I believe this will
help support my description of the issue.
If there are any other logs/versions/traces that I could provide, which
would be useful, please let me know.
Thanks,
Joe
