Video stuttering in Linux
With the latests version of XBMC (complied the 30/07) some of my sample doesn't work (return to the home screen Smile

Try this sample :http://deuch.free.fr/videos/numerous-drop-sample.mkv

The xbmc.log file is not very helping ... There is no mention about the file i'm trying to play

http://pastebin.com/ZhVCZF2g

(I'm using openelec)

EDIT : it "works" if i disabled subtitle. If i play the video and activate the subs, XBMC stop the video and returns to the home screen.

Maybe ffmpeg dlls are not updated?

Ok, new build works (build today an some previous works too). But it still a lot a frame drop (more than 130 for a 1mn opening Smile)

The only way to solve this one is a big change. The overlay rendering is simply too complex to get done in time on the hardware being used. Solution/improvement therefore is possibly

1) to break up the work into separate threads and/or
2) see if there is some way to reduce the processing requirement by being more efficient somewhere and/or
3) to do the overlays work in a separate thread that will not hold up render thread when the overlay work is late to deliver (resulting in overlay data being drawn later than it should be).

I think the last one should ideally be implemented regardless, as it would immediately stop video stutter related to overlays.

Don't expect any solution in the short term though.

I am wondering why everyone is seeming to be convinced of the judder problem to be software related. Isn't it more likely, after months of tweaking and fine-tuning, that the problem is hardware related ?

I'm on Asrock ion 330 ht and the most convincing post I've read until now is the assumption that the balance between the CPU and GPU processing power is way off, and is causing the problem.

Responsible for this non-balance might be a bottleneck which I think is not the the GPU or CPU, but the installed ram people are using. Maybe installing expensive quality ram memory, with perhaps 4 GB, would solve the problem, and might give the CPU space to take over some of the work the GPU is processing now.

Is there anyone here on an ION platform using the highest amount of ram memory possible ?

I yes, what are your findings ?

Is the CPU still running on a low percentage or is the CPU power increased, compared to a low ram memory system ?

Try one of openelecs latest xbmc build for Ion , works "perfect" on my Asrock 330ht playing 720/1080p .mkv and almost zero droped frames Smile

I'm now using the newest official eden build of openelec and I must admit it is a huge improvement. It's almost completely in sync at moments but it still drop some frames time by time.

Could hardware be a improvement ? If someone has experience with extra installed ram please let me know. I'm considering to upgrade my device with more memory but I want to be sure before I buy it.

Try to change "sync method" in xbmc and se witch one works best. (i`m not at home right now, i`ll look tonight when i come home)

Yop,

I'm back after a few more tests.
To recall, i have Openelec 0.9.5 with nvidia G210 (adjust to refresh rate, audio clock).
I am now with a yamaha 667 amplifiers Big Grin.
I set it up to passthroug the audio signal to my 667 via hdmi.
And i always get stutters when i loose the pc at 24 in the info window..., with or without vdpau.

Right now, i still have to :

- test the engine build
- test Fernetmenta build
- be sure that all my videos have correct timestamp, which will hapen if i get unemployed Confused, except i can find a software with a gui which is easy to use (no time anymore to use the console)
- pray god to solve my problem ^^

++

Im using this build OpenELEC_EDEN-ION.x86_64-devel-20111007205438-r8439.tar.bz2
from http://sources.openelec.tv/tmp/image/openelec-eden/ 720p/1080p .mkv works fine @23.976hz if XBMC gui is set to 24hz. If i run @60hz video playback crashes when xbmc changes frame rate.

Sync to display and adjust to refresh rate, audio clock. Almost zero dropped frames Smile
Very nice picture!

Hopefully the fix makes it into eden Smile

Is there a build with the "fix" ?

No, cause they are still testing it. They haven't gotten to the bottom of it just yet.

Just tested openelec eden build from 111111 and could not reproduce the crash on 720p/1080p .mkv @23.978hz, fixed or only luck?
