Title: Loss of Audio / Video Sync During Fast Forward 17.0.59 [Solved]
Post by: Beamer on December 23, 2011, 06:34:08 am

I am unable to fast forward MKV 1080p files without losing audio sync or causing the video to hang. Initially I thought the issue was caused by madVR, so last night I tested MC in standard mode.  Alas I got the same result :'(

I am using Girder to send MCC 10008 (fast forward) and am watching video on an extended monitor.

I reported this issue in the MC16 forum but it was not resolved.

WMC does not have any problems performing the same operation!

Any chance of a fix?

Does it behave the same if you take Girder and the MCC command out of the picture?

No Jim it does not, it works just fine via keyboard commands

Eureka! Looks like pilot error :)

I have changed the commands sent to the following and it now works as expected:
28004   MCC_PLAYBACK_ENGINE_LEFT
28005   MCC_PLAYBACK_ENGINE_RIGHT
28009   MCC_PLAYBACK_ENGINE_NEXT
28010   MCC_PLAYBACK_ENGINE_PREVIOUS

You might use MCC_SEEK_FORWARD / MCC_SEEK_BACK.

The playback engine commands may work, but they're sort of designed for internal use.  Normally there's a playback command (10000 - 19999) that the program will handle and internally convert to a playback engine command (which might vary depending on the playback type, etc.).

Thanks, I have successfully converted to using the MCC_SEEK_FORWARD / MCC_SEEK_BACK as you suggested. This has an additional advantage of showing the time line when executed :)
