Description
Summary of the bug: A working video file becomes invalid after a simple copy
How to reproduce:
% ffmpeg -i broken-example.mp4 -c:v copy out.mp4 ffmpeg version N-102791-gaca923b365 built with Apple clang version 12.0.0 (clang-1200.0.32.29)
You can obtain broken-example.mp4 (3.5MB) here: https://www.dropbox.com/s/tky9p7jmoe8tx4z/broken-example.mp4?dl=1
This began as much more complex failed encoding operation, but this test case is so trivial I believe it will be easier to debug. This input is successfully playable using Quicktime on OSX (although it can't be played with some other players).
What you observe is it begins with a normal video clip, followed by what seems like a slideshow frame. My guess is it is using a variable frame rate to deliver the final slideshow image, but I am unsure how to determine this using ffprobe.
After the encoding the file returned by ffmpeg appears corrupt where the 'slideshow' frame began, approx 9 seconds into the original clip.
For anyone who does not have a Mac with Quicktime, I have prepared a screen recording of the successful playback of the original video here: https://www.dropbox.com/s/qs5ssk8832s5dek/example-playback.mp4?dl=1
I have no doubt the input video file is broken in some way, but I would still like for ffmpeg to be able to operate with it if possible. Thank you for all the work you do to create this incredibly powerful tool.

For future tickets: Please always provide the command line you tested together with the complete, uncut console output.
Understood, thank you for the feedback.
Should I understand that this issue should be resolved by adding -ignore_editlist 1? Unfortunately it's not, this command changes the output but it still stutter and freezes at the offending moment:

This might be a separate issue, but I have also observed that the concat filter terminates the output at this file, even if there are more files to be concatenated, even with ignore_editlist active.

Moving this back to defect just until someone can confirm the new title is actually applicable, given that ignore_editlist 1 does not fix the issue.

To the best of my knowledge, the file has never worked better with older versions of FFmpeg. What you originally requested will likely never work, copying edit lists is not supported.
I believe the file should also work without ignoring the edit list, originally the console output was a little more helpful to find the work-around.

The mp4v2 file breaks the 264 decoder (only without -ignore_editlist 1 that is). File looks like has two different CFR videos, so the file is not strictly VFR.
