I’m not sure if this is the right place for my question but at the same time, I don’t know any better to ask it. So here it goes:
I’m trying to follow the tutorial on the PyTorch website on working with live audio streams. And it’s talking about the fact that PyTorch uses ffmpeg underneath to communicate with the audio driver.
While the examples on the website are pointing to settings on Mac, I would like to replicate the tutorial on my Linux machine. And my Linux machine has got pulse audio. If I open a terminal (without activating any conda env), the ffmpeg installed is version n5.1.2 but the PyTorch tutorial needs ffmpeg version earlier than 4.4. So, it suggests the following command:
conda install -c anaconda 'ffmpeg<4.4'
So I installed ffmpeg 4.2.2. But then, there’s no pulse device available in this installation:
ffmpeg -devices
ffmpeg version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers
Devices:
D. = Demuxing supported
.E = Muxing supported
--
DE fbdev Linux framebuffer
D lavfi Libavfilter virtual input device
DE oss OSS (Open Sound System) playback
DE video4linux2,v4l2 Video4Linux2 output device
This is while I have a whole lot of more devices on my newer ffmpeg:
ffmpeg -devices

My question is, is there any way to install ffmpeg with conda and still have pulse (at least) supported as a device?
