Introduction

Hi everyone! Today I'm going to be giving you a crash course in video processing using Python. Coming out of this talk, you'll be able to take video from pretty much any source, decode it, apply visual effects, and display it on-screen. To do this, we're going to be using a library named GStreamer, an incredibly powerful and versatile framework. This is the same tool that the pros use, but don't feel intimidated! GStreamer actually makes it very easy to do impressive things with video and you'll be well on your way to making something great in just the time it takes to watch this talk.

If you fall behind at any point during the live presentation, don't worry! I have a text version of this talk available with the same content and more. There should be a link in the description.

Installing Dependencies

Let's start by installing everything we'll need to start using GStreamer in Python. This is probably the hardest part, so if you managed to do it before this talk, it's all smooth sailing fro

	[tool.poetry]
	name = "my_project"
	version = "0.1.0"
	description = "A project!"
	authors = ["Tyler Compton <[email protected]>"]
	license = "MIT"

	[tool.poetry.dependencies]
	python = "^3.8"
	requests = "^2.26.0"

	FROM nvidia/cuda:11.2.1-devel-ubuntu18.04 AS gstreamer

	# Adds NVCODEC libraries to the environment for use in building NVDEC support
	ENV NVIDIA_DRIVER_CAPABILITIES=all

	ARG FFMPEG_VERSION=n4.3.1

	WORKDIR /ffmpeg
	# Get FFmpeg dependencies
	RUN apt-get update && \

	local return_code="%(?..%{$fg[red]%}%? ↵%{$reset_color%})"

	if [[ $UID -eq 0 ]]; then
	local user_host='%{$fg[red]%}%n@%m%{$reset_color%}'
	else
	local user_host='%{$fg[yellow]%}%n@%m%{$reset_color%}'
	fi

	local current_dir='%{$fg[green]%} %~%{$reset_color%}'
	local git_branch='$(git_prompt_info)%{$reset_color%}'
