subprocess not creating output file of ffmpeg command

问题 I am trying to run an ffmpeg command that records my screen and creates an .mp4 file of the recording in python. The command works when I run it in my shell, but is not working when I am running it in a Python script using subprocess. The issue is that when running it with subprocess, the output.mp4 file is not created. Here is the command: timeout 10 ffmpeg -video_size 1920x1080 -framerate 60 -f x11grab -i :0.0+0,0 -f alsa -ac 2 -i pulse -acodec aac -strict experimental output.mp4 Here is

Discord bot python: discord.errors.ClientException: ffmpeg was not found

问题 I'm trying to make a discord bot that plays music in a voice channel. It connects to the voice channel, but doesn't play anything. It also gives an error in the console. I'm on Windows and I'm using the discord.py rewrite. My code: import discord, random, datetime, asyncio, nacl, ffmpeg TOKEN = 'What token' client = discord.Client() @client.event async def on_message(message): if message.content.lower() == '$play': if message.content.lower() == '$play': channel = client.get_channel
