Hi all,
I've tried it all, and I still get stuttering with an sftp mount on xbmc 13.1 (openelec 4.0.5 on raspberry pi), so I'm asking for help here.
I've tried playing with buffers in advancedsettings: from force buffering (buffermode set to 1) to no buffer (set to 3). Buffer size from 5MB to 60MB; and read buffer factor from 1 to 8. Nothing helps, I get stuttering and the symptoms are always the same. If I enable the codec info overlay, I essentially see the following:
After some initial buffering, vf and af go to 100%, aq is close to 100% and vq is (suspiciously?) 0%. The reported buffer size varies according to the settings, but in general didn't make a difference. After some playback, vf starts decreasing until it drops to 0%, at that point af starts decreasing too, together with aq. When they reach about 0% playback stops for a while, until all buffers are re-filled, and the usual stuttering problem starts again. CPU is about 60% during playback, and 20% during forced pauses, so I think it's not a horsepower issue.
Please not that in openelec v3 I had the same problem, but if I mounted my remote share with sshfs (rather than via the XBMC interface) then I did not experience stuttering. (I have a steady 10Mb/s connection, and I experience stuttering on streams that take about 0.2Mb/s to stream.)
What else can I try? Any suggestion and comment are welcome!
