Merge Fields freezing in 2.8.1

[IcePlanet]

I'm very happy with Avidemux, but recently I see lot of freezes when processing interlaced content.

My Avidemux (2.8.1) is freezing when applying Merge Fields filter from Interlacing section. What I'm trying to accomplish is to convert from 50 FPS 1920x540 to 25 FPS 1920x1080.

The freeze occurs at end of first pass. Empty dialog box is thrown and Avidemux freezes.

Have found similar topic here but it seems as abandoned or resolved (depending what posts you look at).

Below is information about video file, py script and log file from Avidemux ending with:

[ADM_Composer::nextPictureInternal] 20:39:12-839 Next image PTS in ref is out of range: got 3951040000 us, wanted < 3951025378 us, discarding the image

Have I done something wrong or is this bug?

Edit: There are cuts done to the file, but cuts are done only on keyframes (with up and down arrows).

I've fixed the issue of timebase being not recalculated in the "Merge Fields" video filter, not able to reproduce a crash (yet) using the current git master. Please try a future nightly.

Thank you for the fix. Will check when next nightly is available. Currently I see latest nightly from 8 SEP 2024.
