fixed Track Replay problems

[BIGNEWY]

A potential fix will be in the next patch. Please try new tracks after and let me know if it helps. ( old tracks may still not work between versions )

I haven't used the DTC yet as it is only concerned (at this time) with countermeasures and yet I cannot view ANY saved track that I have flown i.e. as PLAYER, I am aware that we all have our little axes to grind but for me, as mentioned before, not being able to view and edit a track for use as YT content, renders DCS, for me, of little practical use..
I sincerely hope  this problem is rectified in the next update.

I've rolled back to 2.9.13.68 version for that reason. After the save state was introduced in 2.9.14 tracks started desyncing at a massive rate, talkign about short guns only FC aircraft vs AI. The latest 2.9.15 is just as bad desyncing wise with FC craft, and also has the "unexpected end" to boot. The patch note says that the latter was addressed, but it was not.

I just did a very quick test, simple mission - F-16 flying toward a runway PLAYER controlled, after exiting and clicking on WATCH TRACK the track played failed with the usual error message, for clarity, this problem is new and seems to have started around the time of the new SAVE 'feature'
I have to admit to being really disappointed...

Hi, as you can see in my post above, the problem remains.  I have to assume this problem affects everybody that tries to load a saved track, given that there are not hundreds of posts about this I have to assume that not many people use / edit a saved track?  Can anyone out there in DCS land save a track after an (F-16 or F-18) PLAYER mission   and then successfully reload that same track?

I will check with the devs using your tracks, thanks

We have tried to reproduce and have been unable. 

Your track shows the error, the headers are corrupt. But when we try to reproduce we can not. 

 

Can you let me know what and how you are saving the track. Break it down so I can try to reproduce it exactly. 

Could you also do a slow repair and also rename your dcs folder in saved games ( keep it as a back up ) 

And test fresh. 

thank you for helping

Ok, all done. No change.

Sequence:

Load DCS from bin-mt dcs.exe

Mission Editor

New Mission

Caucasus

Select (in this case) F-16

Place on map

Select PLAYER

Create 1 waypoint

Save mission

Run

Exit

Save track

Watch track or simply Watch track without saving - result is the same

As mentioned earlier, I have repeated this sequence for 5 years and created over 500 videos using the saved track combined with nvidia shadowplay without ever seeing this issue.

Looking at the log I see that 24H2, which is recent, is parking logical cores - I will turn this off again and retest.

Thank you, it seems so simple but using your method I was able to reproduce and have reported. 

appreciate you taking the time to break it down.

Ha!  Hurrah! Thank you!

The "end of track fiber" problems are now solved, thank you!

But! Replay tracks became much less reliable in general, starting with version 

DCS World	RELEASE	2.9.14.8222	03/19/2025	MISSION STATE SAVE, 2 NEW CAMPAIGNS, HOTFIXES

The last reliable DCS version for stable track playback was

DCS World	RELEASE	2.9.13.6818.2	03/05/2025	CAMPAIGNS UPDATE HOTFIX

I still have 2.9.13.6818.2 and have tested all the subsequent versions, including the latest 2.9.16.10523. The simple short shingle player mission against 1 AI plane never desyncs in 2.9.13 and almost always desyncs in all versions after. A typical short track is in the attachment.
