.MOV HEVC+PCM playback regression with files longer than 2 hours

[DfactorLongplays]

After upgrading from 2.3.9 to 2.4.0 the player no longer plays back 2+ hours long .MOV container files with HEVC+PCM encodes.

The file opens, the player shows a still frame, says that it's playing, but the video remains still. Using arrow keys or clicking on the seekbar brings up the correct frame, but playback remains frozen.

Strangely, the last ~80 seconds of the video do play back, but without any audio.
Currently, this issue affects K-Lite 18.8.0, Standalone 2.4.0 x64 zip.
Meanwhile, in Standalone 2.3.9 the playback works as intended.

This problem is persists across multiple different .MOV files, while a 100 minute long .MOV file with the same encode settings is playing back normally.

K-Lite 18.8.0 with a 7 hour long encode.

Must be a regression in updated FFmpeg code.

I need a sample file.

Here's the smallest file I have that meets the criteria (10.6GB, 139 minutes).

Can you take a look?

ffplay 2025-01-08-git-251de1791e is ok
ffplay 2025-01-13-git-851a84650e has no sound
so must be regression due to 292c1df
