͏    I won't download the video samples.
͏    But you may try running certain `ffprobe` commands that reveal the input characteristics.

I was request they try reinstall windows. Only their computer crash, it work well on my computer.

[MasterQuestionable]

͏    Don't hurry to do so.
͏    Is "ffmpeg-20240828-155140.log" generated by you, or their computers? (rough parse didn't find error..?)
͏    Report the OS (all Windows?) version and exact CPU models all involved.
͏    Also the RAM size correspondingly.

͏    "crash when render"
͏    I suppose `ffmpeg` doesn't render: it decodes and encodes. (render implied playback)

͏    What's the error message in "ffmpeg-20240828-155140.log"?
͏    I didn't find it.

͏    Did the program just abruptly stopped? (so incomplete log)

͏    Does using "-an" to disable audio still cause crash?
͏    What about using another FFmpeg build:

-It crash, so no error message, the code of ffmpeg not handle it. (may be some dll on that window error and return wrong value, so i request them try reinstall window)
-That filter work, and run well on my computer.
-That output from my library ​https://github.com/tqk2811/FFmpegArgs
(​https://gist.github.com/tqk2811/29b4a8567d11d5e4cad0d41f1bfcf2ae)
-i will try again on their computer with -an

[MasterQuestionable]

͏    There appears to be significant no-op in the filterchain.
͏    Try dissecting and reduce?

͏    Also, as the crashed is "avcodec":
͏    Would mere transcoding each file independently, without the filter reproduce?

Oh, it crash with only ffmpeg -i input.mp4 -c:v libx264 -b:v 3000K output.mp4
and ffmpeg -i input.mp4 -c copy output.mp4 not crash

[MasterQuestionable]

͏    What happens?
͏    ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i "testsrc2=1920x1080:30:d=5" -c:v libx264 "Out.mkv"

͏    And in different Windows builds?

[Truong Quoc Khanh]

ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i "testsrc2=1920x1080:30:d=5" -c:v libx264 "Out.mkv"

[Truong Quoc Khanh]

Out.mkv: ​https://drive.google.com/file/d/1RjDH5VXZjASp4Rxj43wc8Z0sXno6Y60E/view?usp=sharing

Sorry for late response, It is quite difficult to communicate with third parties

[Truong Quoc Khanh]

ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i "testsrc2=1920x1080:30:d=5000" -c:v libx264 "Out.mkv" work well (changed to 5000s). Then crash only when decode

look like crash when decode video

But ffplay can play video without crash

[MasterQuestionable]

͏    I guessed much what's going on.
͏    I believe the problem is likely specific to their deployment: mostly just corrupt program files.
͏    Probably not something can be fixed upstream.
͏    Potentially a build problem?

͏    Note:
͏    I'm not sure I perfectly understand your every statement after comment:14.
͏    Questions:
͏    |1| All listed commands resulted in alike crash of "avcodec"? (as in comment:description)
͏    |2| Are all the FF-* tools of the same build?
͏    [ ^ Per the command logs apparently not: later ones are of 6.1.1-20240130?? ]

[Truong Quoc Khanh]

1: Yes, all crash in window event viewer is avcodec

2: Since log.txt​, all file i upload is 6.1.1..... ​https://gitlab.com/tqk2811/FFmpegBuildSubmodule/-/tree/master_6.1/out/ffmpeg-n6.1.1-1-g61b88b4dda-win64-gpl-shared-6.1/bin?ref_type=heads
And before, i was tested with many versions 5.0, 6.1, 7.0,...
