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 leaksExtracting 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 C programmers use with FFMPEG.By the end of the 2nd part learners shall grasp these data structures:AVFormatContextAVPacketAVFrameAVFormatContextAVRationalAVMEDIA_TYPE
