Issue with libopenh264.so.5 while running n3v2blender.py script

[SHIBOYA]

Dear Zeyu,

I am currently working with the 4D Gaussian Splatting project and encountered an issue while attempting to run the n3v2blender.py script. When I execute the script with the following command:

python scripts/n3v2blender.py /root/autodl-tmp/N3V/cut_roasted_beef

I receive the following error message:

==== running: ffmpeg -i /root/autodl-tmp/N3V/cut_roasted_beef/cam20.mp4 -start_number 0 /root/autodl-tmp/N3V/cut_roasted_beef/images//cam20_%04d.png
ffmpeg: error while loading shared libraries: libopenh264.so.5: cannot open shared object file: No such file or directory
FATAL: command failed

I have tried several solutions, including installing the openh264 library and adding the libde265 repository, but the issue persists. Here are the steps I followed:

1. Tried to install openh264 directly using sudo apt-get install openh264, but it was not found.
2. Added the libde265 repository and installed it manually:
   • Added the repository using sudo add-apt-repository ppa:strukturag/libde265
   • Installed openh264 using sudo apt-get install openh264
3. Downloaded and manually installed the OpenH264 library from GitHub:
   • Downloaded the library using wget
   • Extracted and moved the library to /usr/lib
   • Updated the linker cache using sudo ldconfig

Despite these efforts, I still encounter the same error. Could you please provide guidance on how to resolve this issue or any additional steps I might be missing?

Thank you very much for your time and assistance.

Best regards!

This works for me: link ; try also which ffmpeg to find the path and then deactivate if it's in /usr/lib/ dir

After install ffmpeg, I encountered an error while running train.py. The error message indicates "Could not recognize scene type!".
