Jerky movies with DVDplayer (split)

[JRLS]

Edit: Most movies also almost stop at the very beginning of playing for a few seconds.

i have the exact same problem!
at the beginning of a movie the first few seconds the movie stops/stutters (sound is working), and then after a few seconds, it runs normally.
with older build of xbmc i didnt have the problem.
movies are playing from a synology nas server, so it's just an .avi file.
i think it's 3.5 related

any ideas?

@JRLS - i have the same issue with media streamed from my computer via smb. never really bothered me tbh as i always move the video back to thge start while i can the aspect ratio. I always thought it was just the buffer being filled as moving it back to the start of the video didnt have the same results once played, it only seems to stutter the once thats why i thought it was maybe the cache buffer or something like that. really not a big deal at least for me anyways

Could all this be due to the memcachebuffer size? What are your all settings?
I get all of this and have my advancedsettings set at 16mb cache, with ram and 1ghz upgrade
I make sure HDD spindown is off as well.

I also played it from HDD. Same issue: first 5 seconds laggy video.
video is .avi file: mpeg4 (xvid), yuv420p, 464x352 (SAR 1:1 DAR 29:22)

then, I tried the advancedsettings.xml in Q\userdata

tried caching via HDD:

Code: Select all

<advancedsettings>
  <network>
    <buffermode>1</buffermode>
    <cachemembuffersize>0</cachemembuffersize>
    <readbufferfactor>10</readbufferfactor>
  </network>
</advancedsettings>

I do not see any difference.

Next i tried with bigger buffer:

Code: Select all

<advancedsettings>
  <network>
    <buffermode>1</buffermode>
    <cachemembuffersize>157286400</cachemembuffersize>
    <readbufferfactor>20</readbufferfactor>
  </network>
</advancedsettings>

I do not see any difference.

In other words: no difference.
Any ideas?

i thought it was down to the native cache settings on the xbox. Once your videos have stuttered for the first few seconds if you go back to the start does it do it again? if not then some sort of buffer must be filling maybe?

hi Keith,

I'm using XBMC 3.5
when a movie is started, the first 5 seconds, the video is laggy.
When it's playing normally after 5 seconds, and then if you go back to the start of the movie, or restart the movie, it plays fine.
If you choose another movie however, it's again laggy. Maybe a buffer problem.

Then i started up a really old version i was previously using, which is:
XBMC 9.11-alpha1-r24238 (compiled: nov 8 2009)
Mplayer XBMC-SVN-f17397 (Jan 27 2009: 23:40:31)
This version plays everything just fine, with no lag at all!

Does not matter if i play from HDD or change the buffer settings, 3.5 is still laggy in first 5 seconds.

Maybe it has to do with the MPlayer version?

ah well im sure with that old build that mplayer would be the default player but since so much mwork has now gone into xbmc4xbox the dvdplayer has become the default player due to its many upgrades and improvements.

i think i may have a few old ones of those builds so i will load one on my xbox and do a quick test. furthermore its worth checking what settings the cache are at on the old build compared to the new build and changing it to see the difference (if any)

[JRLS]

if you want to check the settings, that would be great !
hopefully it's as simple as that!

[JRLS]

any progress yet?

nope i tested with a few old builds but i couldn't see what you described, all the ones i have slightly stutter at the start (which never bothered me anyways tbh) i assume it filling some sort of network / cache buffer or something like that
