I’m reading the PyTorch tutorial and it’s saying that PyTorch works only with the older versions of ffmpeg. Namely, earlier than 4.4. They suggest installing it through conda: conda install -c anaconda 'ffmpeg<4.4' This works perfectly fine other than the fact that the installed ffmpeg does not re…

ffmpeg4.4 is already available in the repositories. Have you tried installing it?

Is it AUR or Official repo? When I search for ffmpeg in Pamac, a huge list of items is returned. I tried looking into some of them but they are mostly version 5.x or even 6. I don’t see any 4. I thought maybe version 4 is considered too old. Can you help me find it? BTW, it has to be earlier than 4…

pacman -Si ffmpeg4.4 :wink: [image] mehran: it has to be earlier than 4.4. Like 4.3 or 4.2. Why? python-pytorch dpends on ffmpeg4.4.

This is a quote from their tutorial page : This tutorial requires FFmpeg libraries (>=4.1, <4.4). There are multiple ways to install FFmpeg libraries. If you are using Anaconda Python distribution, conda install -c anaconda 'ffmpeg<4.4' will install the required libraries. I do see ffmpeg4.4 in …

I think you missed my ninja edit: [image] Yochanan: [image] mehran: it has to be earlier than 4.4. Like 4.3 or 4.2. Why? python-pytorch dpends on ffmpeg4.4. [image] mehran: This tutorial requires FFmpeg libraries (>=4.1, <4.4). The documentation may be out of date.

OK, then. But I have another question. Since I already have ffmpeg4.4 installed as well as ffmpeg (which is 2:5.1.2-1 - whatever that means), how can I use the 4.4 version? Right now, when I try to run the code that is supposed to talk to ffmpeg: StreamReader( src="1", format="pulse", ) I…

Do you know where can I find the executable file for ffmpeg4.4 if I also have ffmpeg 5.1.2 installed? It’s not in any of the two directories you’ve mentioned. Perhaps I can make a symlink to /usr/bin/ffmpeg (which right now is 5.1.2) and fool the Python code! Looking at the list of files (provided …

[image] mehran: Perhaps I can make a symlink to /usr/bin/ffmpeg No, don’t do that. There is no separate binary in the ffmpeg4.4 package as you noticed. That’s on purpose. I know how to build a package to tell it to use ffmpeg4.4 instead of the default ffmpeg, but unfortunately that’s the end…

I really appreciate your help, @Yochanan . I’ve made some progress but I could still use some help. It would be great if you could guide me for this last step as well. After our conversation here, I thought it might be better if I try to compile ffmpeg4.4 from source. Especially since I saw where c…

I’m not a Python developer, so that I do not know.

You should be able to specify the paths somewhere: /usr/lib/ffmpeg4.4/ & /usr/include/ffmpeg4.4/.

Perhaps this may help:
