OpenELEC (Milhouse) - Version: devel-20141005212029-r19335-gf89d7f8 [Build #1005]

  • Includes newclock4 patches
  • Excludes the OpenELEC fernetmenta patches due to conflicts with newclock4
  • Excludes the OpenELEC linux-01-RPi_support patch in favour of sourcing these and possibly more recent patches directly from kernel branch rpi-3.16.y
  • Excludes the OpenELEC xbmc-001-newclock4 patch in favour of sourcing these and possibly more recent patches directly from newclock4 branch
  • Default setting for "Show RSS Feed" changed to disabled

Did you noticed that when you have
-Audio Output > Output configuration: Best match or Optimized
-Acceleration > Allow hardware acceleration (OMXPlayer): enable
then you play a HD audio file with DVDPlayer (so OMXPlayer),
the sampling rate is down-sampled to what is set in
-Audio Output > Output configuration: fixed (hidden)
but never up-sampled Huh??

Everything else left untouched, and still I got the stuttering and identical error messages. New log uploaded here: http://xbmclogs.com/show.php?id=310224 (please note that log is from after I updated from 0924 to 1004 but results are the same in both versions).

Also tried all the changes to advancedsettings that you suggested (on my original setup), didn't make a difference.

The Pause/Resume sequence means we are not reading data in fast enough. That normally means a network issue. Is it a wired (rather than wireless) network connection?
The fact you had a problem with a usb disk is surprising - can you copy a video to sdcard and report if that is okay?
Can you check dmesg (ssh in and run dmesg) and see if any messages appear when playing the video?
Can you check voltage on Pi?

The connection is wired.
I'm getting the same errors when playing a file from the sdcard.
Nothing reported in dmesg when playing file or when stuttering occurs.
Don't have a multimeter available at the moment, but will try to find one. I have another Pi with a different power supply, will try with that one as well.

Got my hands on a multimeter, voltage is stable at 4.97 both when idling and when playing (and stuttering).
Tried two other power supplies as well, same thing.

Also tried moving my sdcard and usb stick to another Pi, same result. Could it be a problem with sdcard or usb stick?

Any other ideas?
I also had the problem with stuttering videos from network and local storage 2 weeks ago. For me it was the SD-Card which somehow got read-only even when the switch wasn't set to locked. Try to access the SD-Card on a linux-system, when you're able to write everything is fine if not, you should probably try another SD-Card.

@MrNice
Can you try playing with this setting?
It defaults to 100ms of audio buffer. You can change it between 50ms and 300ms. Can you test if any settings help with audio dropouts with your audio files.

The read-only sensor isn't physically connected on the Pi circuit board, so the switch/lock on the SD card has no effect whatsoever.

If your SD card becomes read-only, that would be because the fileystem is corrupted in some way and needs to be fscked.

...Keeping in mind that the SYSTEM partition is supposed to be read only, and if the STORAGE partition was read only, he could not have copied a file to it (as he did).

Yeah, permissions seem to be correct.

I tried with 50ms, 100ms (default) and 300ms. Nothing changed to better/worse

Some feedback for #1005 Finally timeline epg opens really fast and live tv running fine in background without stutter and slowdows. Thanks popcornmix ?

Is this dvdplayer or omxplayer?
Was #1005 the first build that behaves better?

Yeah I know (and I did fscked it), but the complete card was somehow damaged (since now I don't know how and what exactly was damaged). Pi couldn't write files on it (what has worked before) and the SD itselfe wasn't even writable over ssh. I tried to set it up fresh but writing the image failed because of (not really) set lock. However even with linux and root the system wasn't properly installed out of the tarball, so I used another SD Smile .
But back to his problem: Trying another SD would eventually help to get rid of the stuttering vids.
