ffprobe returned malformed data

[HCchay]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with the newest version from GitHub (also it might have already been fixed in latest nightly build)
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions
• This problem happens with all kinds of files that I try. For problem only with a particular file or type, use this other form instead

Operating System

Windows 10

Steps to reproduce

If you try to drag the video shown in the image into the software, you may encounter an error.

Expected behavior

ffprobe returned malformed data

Actual behavior

There should be no problem.

Share log from developer tools

this happens with all files?

[mifi]

your log file doesn't seem to capture the event when you drop this file. can you try again and submit a new log?

1. open losslesscut
2. open the file
3. share the log from developer tools

[HCchay]

There is no log in file. It's only in help

[mifi]

can you share a file that gives this error, or run this command on the file and share the output:

ffprobe.exe -of json -show_chapters -show_format -show_entries stream -i "C:\Users\cassiushe\Videos\bandicam 2025-01-13 11-19-41-601.mp4" -hide_banner

note you might have to install ffmpeg.

Using cmd seems OK？

[mifi]

thanks. it looks correct to me. I honestly don't know what's wrong here, because I cannot reproduce the problem without your file. I will add better logging in the next version so losslesscut will log the output from ffprobe.

[HCchay]

thanks

[HCchay]

I discovered that the issue seems to be caused by spaces in the video file name. The import succeeded immediately after I removed the spaces. However, what's strange is that this same video file with spaces in its name was successfully imported this morning before I made any changes. In fact, I even edited it and exported successfully. Later, when I moved the LosslessCut software to a different location and tried importing the same video file again, the error message reappeared.

[HCchay]

So I’m not entirely sure if it’s caused by spaces. I hope the author can look into this issue in future updates.

[HCchay]

When I import the video again with the space removed. The same error was reported again.

[mifi]

Ok, so it doesn’t have to do with spaces, right? Does it happen with all files or just that particular file C:\Users\cassiushe\Videos\bandicam 2025-01-13 11-19-41-601.mp4 ?

Also what’s the location of losslesscut when you’re getting the error?

[HCchay]

all documents

[HCchay]

In the C drive, Downloads folder...What’s strange is that no matter what I do on my home computer, it works fine. This issue only happens on the company computer.

[mifi]

I’m wondering whether it could be an issue with some security software or antivirus on your work computer that prevents losslesscut from calling ffprobe.exe (or intercepts it replacing its response)

[HCchay]

I don't think so. I added this folder to the trust zone.
