Assertion `length + 4 < maxlength' failed about untrunc HOT 5 CLOSED

Ciao, that assert infact looks wrong. I have remove it. Sorry.

Thanks for finding it.

from untrunc.

Looks like I'm experiencing similar:

The broken file is 724MB MOV from a Canon DLSR. The reference file is 258MB. I tried with a 3.1GB reference file but got a std::bad_alloc.

from untrunc.

Tried different reference files and also truncating the broken file with truncate, down to 200M, now get segfault with no further information (if you can let me know anything I can do to help debug this let me know, including supply video files)

Segmentation fault

Tried the old code also which does the same thing.

I tried recompiling untrunc after commenting out line track.cpp:124.
The program now runs without errors, but unfortunately the output video file doesn't work.
Is this bad luck with my file, or maybe commenting out that line actually breaks untrunc silently?

Same issue as rjgscotland. Resizing the mp4 to < 200M resulted in a broken video stream. Ended up using yamb to successfully rescue my mp4 file.
