infer/lib/audio.py: audio2(): av.open(..., "rb"|"wb"): ValueError: mode must be 'r', 'w', or None, got: rb

[dimgel]

Hi. Got error when trying "Model Inference" tab, had to patch subj to get it working:

-   inp = av.open(i, "rb")
-   out = av.open(o, "wb", format=format)
+   inp = av.open(i, "r")
+   out = av.open(o, "w", format=format)

It was just a guess. I don't know python, couldn't find API docs nor what "b" means. "Binary"? Ha, can it also process text files? :)

Also hit #1155 on first run, 1st comment there helped. Didn't try anything else yet.

ArtixLinux, python 3.11.8, ffmpeg 6.1.1 & 4.4.4, nvidia blob.

I meet that question too.In python,"rb"means you need to read a binary file.In function "open" it works,so I guess that's the question of av library.I want to solve that too:(

I want to solve that too:(

Then just remove "b" like I did -- and it will work.

Sorry, not my area of expertise.

@dimgel, @WuYuZh17: Looks like this commit makes it so you can't use 'rb' in the open anymore which was being used in the latest release here.

Try installing an older version - PyAV v11.0.0
pip install --force-reinstall -v "av==11.0.0"

@JarrodElliott , downgrading av from 12 to 11 fixed the issue for me!
