transparentvideo mode is not working about backgroundremover

[durgabhavaniv]

same for me also with 0KB video output.

[nadermx]

both on ubuntu 18? I haven't tested it on ubuntu 18, only 20. Although I don't see a reason as to why it woudn't work. Can you do just the matte file? (green screen) backgroundremover -i "/path/to/video.mp4" -mk -o "output.matte.mp4"

Thanks a lot for your work, I have been looked for such a tool for many weeks !

On my side, I'm working on Ubuntu 21.10 with :

• Python 3.9.7
• Torch 1.10.1

Handling of Images works fine.
For video files, it gives me an output file of 0kb.

I tried to generate the matte file and it works as expected, I get a valid video file.

Let me know if I can do other tests to help you fixing this issue.

[nadermx]

Do you have FFMPEG 4.4+? If the Matte key is working, then the removal is working so it's probably something with the ffmpeg version. Either way I have to rewrite that part to make it work on msft

Here is my ffmpeg version :

I had the same issue as you guys.

The problem for me was that I was using a .webm file. I don't know what this support but I changed the webm to mp4 with ffmpeg and the output to .mov and it worked for me.

[ExtremeHobo]

I am having the same issue on Windows 11
Python 3.6.8
ffmpeg 4.4.1 and also attempted newest 2022 branch
torch 1.11.0 - no CUDA

I have tried mov, mp4, webm, avi etc for the intial input and mov and mp4 for the output. Anyone ever find a solution?

[nadermx]

I really need to spend time to fix a few of these issues. Just the desire is a bit on the low side at the moment. If anyone wants to pull request... All this need is the file paths to be corrected to work on windows as well

I understand that all too well! great project here btw

[j2l]

Hello,
Congrats @nadermx, you have a great project and helpful community!

I also have the same behavior on Ubuntu 21.10, CUDA 11.6 (while only 11.3 for pytorch), stock ffmpeg (4.4-6ubuntu5), python 3.9 (couldn't find 3.6-dev).
Full error is:

backgroundremover -i test.mkv -tv -o removed.mov

I made it work!

You just needed to take care of a few things:

• no webm or mkv as input, transcode to mp4 first with ffmpeg ffmpeg -i test.mkv input.mp4 or else
• use quotes "output.mov", and also relative path for input "./...mp4"

I still have issues with colors and frame rate in VLC:

[nadermx]

My bad on this one. I dont think th merge request fixes this issue. The issue is that you are trying to output a mp4. Mp4 doesnt have a container. It has to output a mov or gif. Unless I am misunderstanding @j2l commented with the solution.
