FLV Fix option corrupts files

On version 6, 7, 2022 many of my .flv files get corrupted, unwatchable after Flv Fix. On version 5. everything worked flawlessly, but unfortunately that version won't support batch fixing of many flv files. Please try an example attached. Interval 15, "fix interval".

That file is recorded from a site that is not streaming using fixed durations.  This is common with live webstreams.  The avg duration is 56.  Setting it to 15 will not work.

What are you trying to achieve by fixing it as it plays back fine anyway?

I am trying to make it playable with online doodstream flv player. It can not find where video begins in fact (VLC can), and plays single frame for 10-20-30 minutes, making it very uncomfortable, needing to click manually on progress bar and look will picture move or not. (VLC somehow knows the offset start position and jumps there automatically)

PS: i wrote win automation script and convert all my collection in batch with older working Jaksta5 fixer. Setting "12" ms is tested to be ideal for my files, speed is ok and audio uninterrupted.

I just tested the provided video with 12ms in v2022 and it does indeed play back fine.

Yes same version and Im on Windows 10.  Playing back in VLC 3.0.17.4.

This is what it shows after the fix, with the avg interval now 12, and the duration now rebased to 3:46 (which is the duration captured) instead of 17:41 (which is now long the live stream had been live for).

    

The video plays back from 0 through to 3.46.

Interesting that your video shows a frame rate of 83.333 once fix is done,  mine shows 30 fps.

Please provide debug logs as per https://www.jaksta.com/support/windows/technical/jaksta-media-recorder/how-to-generate-debug-logs-6000009063

Tried fixflv on win10 virt.machine. After fixing it showed in table: 30 fps.  But exported file was unplayable, blank screen with sound, as in Win7, and MediaInfo app showed... 83.33 fps.
