Seek doesn't always work - 2.7.5 14th March Win64 Qt5 [Solved]

[Faiakes]

With some video files I can no longer drag the seek bar and move to another part of the video.
There is only a black frame displayed.
It makes no difference if the video in on play or stopped.
I tried the portable version too. No difference.
This seems to have started after receiving the latest Win10 update, but I could be wrong. ( I am on 1909, aka 10.0.18363.720)

Does it mean that it worked fine with older Avidemux builds?

I doubt that this has anything to do with the operating system (disabling DXVA2 hw accelerated video decoder in Avidemux preferences could give a clue). A very probable cause might be a video with codec settings changing midway, a scenario Avidemux cannot handle (never could, so an earlier build won't make a difference).

While using the latest Avidemux nightly (as you do), please load such a file, reproduce the problem, close Avidemux, then compress (zip or 7z) and attach admlog.txt from %localappdata%\avidemux\ to your reply in order to allow to assess the situation.

Done. Also, here is one of the files in question:

Should be fixed by [coreUtils/infoExtractorH264] Trust NAL if a slice is marked as IDR and we don't have SPS to verify.

Thank you very much for your report and the sample.

Will wait for next version.

A win64 MinGW build with the fix included is now available --> https://avidemux.org/nightly/win64/

Yes, I tested it and it works!
