Description

Turn FFMPEG commands into code using the C programming language. Handle FFMPEG Data Structures like a Pro Engineer.

What You'll Learn?

Learn advanced FFMPEG Data Structures i.e. AVPacket, AVFrame, Sws struct etc
Extract raw audio as 32 bit floats
Extract individual picture frames from video data
Convert grey images to color JPEGs using the libswscale and STB Image C library
Use the PPM image format to write pixels to file
Manipulate raw audio data using Audacity
Manipulate raw audio floats in unsigned 32 bit format
Use the C Int Types library to work on raw integer data

Who is this for?

Beginners who desire to learn the FFMPEG API in C

Programmers who want to get into the video and streaming industry

Teams that handle audio and visual content

What You Need to Know?

Basic grasp of C programming

More details

Description
You can code on your phone or laptop. No installations necessary! Super accessible course thanks to Replit!
FFMPEG is an audio and video library used by Netflix, TikTok, Comcast and Disney engineers to manipulate audio and video. This is the second part of a series on using the FFmpeg in the C programming language.
This section places emphasis on
Freeing memory correctly and using Valgrind to investigate FFmpeg memory leaks
Extracting pixels from images.
Working with PPM and JPEG image formats in C.
Finding raw audio samples and writing to a file stream.

Video coding engineers earn a basic salary of 180k and companies like NETFLIX pay video coding engineers 900k total compensation.
This video series introduces video coding to committed learners. We emphasize using the C programming language, not the command line. The goal is to make accessible video and audio coding to programmers who desire to work in HIGH-PAYING fields. All the code is written in Replit, an online IDE, to allow programmers to code alongside the instructor. Again, the instructor's goal is to make accessible video coding.
This course introduces learners to the FFMPEG C API. Unlike courses that teach the command line, this series focuses on writing code in the C programming language.
Students are taught -
How to navigate the vast FFMPEG documentation.
The data structures available to C programmers.
Tips and Tricks professional CÂ programmers use with FFMPEG.
By the end of the 2nd part learners shall grasp these data structures:
AVFormatContext
AVPacket
AVFrame
AVFormatContext
AVRational
AVMEDIA_TYPE
Who this course is for:
Beginners who desire to learn the FFMPEG API in C
Programmers who want to get into the video and streaming industry
Teams that handle audio and visual content
