Hi,
This is an issue I've had for a while and have finally narrowed it down a bit further to DTS MA being a contributing factor. Skipping through ripped blurays with DTS MA audio results in long pauses (up to 5 seconds) during the seek. It doesn't happen with every seek. Sometimes it's the first one. Sometimes it's the 20th.
Here's my setup:
-RPi2 running LE 7.0. (issue also happened with previous OE builds and with Milhouse 8.0 testbuilds)
-Unraid NAS. Content shared via SMB. (Issue also happens with NFS and local, flash USB storage)
-Skip Steps at -10s and 30s. Skip delay=None
-Debug log: http://pastebin.com/Nq9upHbj
The seek in question starts at:
10:11:09 38.586525 T:1963278336 DEBUG: OnKey: right (0xf083) pressed, action is StepForward
there is a long pause (this one is 4 seconds) until the video resumes at:
10:11:13 42.188492 T:1963278336 DEBUG: ------ Window Deinit (DialogSeekBar.xml) ------
-Other Info:
--Doesn't happen with content containing 5.1 DTS Core audio only. If I rip the same bluray with just the DTS Core track, I can't reproduce or notice any pauses.
--It doesn't happen at the same time in the video every time it's played. But it seems more likely to happen at the same time.
--It happens with OMXPlayer or MMAL. MMAL is enabled for this log
--Adjust display refresh rate is enabled. (happens when disabled too)
--Sync playback to display is disabled (happens when enabled too)
--I've tested my network for throughput and drops with iperf and it is fine.
--It may be happening to a lesser degree on windows, but isn't really noticeable due to it's speed.
--The pauses also happen if the media contains both a 7.1 MA and 5.1 Core track, but the 5.1 track is being played.

Any suggestions or thoughts?
Thanks!
