heroku-buildpack-ffmpeg-latest | Heroku buildpack for ffmpeg | Platform As A Service library

I would like to use FFMPEG for my bot that I want to host on Heroku. For this I installed the following buildpack: https://elements.heroku.com/buildpacks/jonathanong/heroku-buildpack-ffmpeg-latest. I added some checks in my source code to check the FFMPEG path:

I'm trying to open a videoURL using cv2.VideoCapture on Heroku, and it consistently fails to open. I've called the same code on my local machine (Windows 10) and it ran with no problems. Does anyone have recommendations/buildpacks/alternatives to resolve this?

OpenCV Version: 3.4.2.16

Python: 3.7

Current Buildpacks:

• https://github.com/cstavish/heroku-buildpack-vips.git
• https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git
• https://github.com/heroku/heroku-buildpack-apt
• heroku/python
• https://github.com/timanovsky/subdir-heroku-buildpack

Open Cv Build info (Video) from the Heroku Dyno

My bot is all set up and running, everything works, EXCEPT for voice: He joins the channel, but doesnt play audio. I have heard many different claims for what the reason is (no permission to use ffmpeg.exe, missing buildpack, missing dependency, Heroku blocking UDP on free users...) - but i hope that someone here ACTUALLY knows what the problem is, because i couldnt find any definitive reason online.

This is the code of the bot: https://github.com/FlyingThunder/DiscordBot/blob/master/main.py Everything is working fine on my machine. This is the only error that Heroku logs gave me: 2020-07-24T06:28:30.329937+00:00 app[worker.1]: PermissionError: [Errno 13] Permission denied: 'res/ffmpeg.exe'

I already tried adding https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git to my buildpacks, and i added cffi==1.14.0 to my requirements.txt - both solutions that are supposed to fix this exact issue.

I want to use the ffmpeg buildpack in my Python app on Heroku.
I am using the ffmpeg buildpack from https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.

How can I use buildpack? subprocess? os? How to call the ffmpeg? Anybody can teach me?

This is my code and I want to convert mp4 file to mp3 file. Actually,I don`t know about the detect/compile/release file.

I am trying to host a discord music bot in heroku, but even if it works fine in my local machine, it doesnt seem to be able to find the libopus library deployed.

Here is my requirements.txt file:

I'm having trouble setting up my music bot to work with Heroku. It works perfectly fine on my host machine, however, I get an "Opus Not Loaded" error when I run the bot in Heroku. I already have a ffmpeg buildpack(https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git), an apt buildpack (https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git) with the Aptfile fully setup (see below), and I have an opus buildpack (https://github.com/dubsmash/heroku-buildpack-opus.git). I also have youtube_dl and discord.py[voice] in my requirements.txt file

Here is the contents of my Aptfile.

I've made a bot that deals with gif files and I tried uploading it on heroku.

So I've installed this buildpack https://elements.heroku.com/buildpacks/jonathanong/heroku-buildpack-ffmpeg-latest

And I run this code as a subprocess:
