Introduction If you're working with multimedia applications or video production, you may often find yourself in a situation where you need to encode video with specific settings like H.264 codec, MP4 container, and controllable frame rate and bitrate. libavcodec, a vital component of the FFmpeg multimedia framework, can help you achieve this. In this guide, we will walk you through the steps to encode video with these requirements and introduce you to the concept of presets to control encoding quality. Encoding with libavcodec libavcodec is a powerful library for encoding and decoding audio and video streams. To encode video with H.264 codec and MP4 container while controlling the frame rate and bitrate, you can use the following.   Set Encoding Options: To control the encoding quality, you can set the encoding options using the AVDictionary structure. In this case, we'll focus on the 'preset' option, which defines the encoding speed and quality.  The available presets ...

 As beginners, We mainly focus on the view that we have in front of us and as a human, we look for where there is a crowd and look mostly where there is most opportunity. But this article aims to look everywhere to gain a broader view.   At the beginning of the software development journey and open source exploring, I felt the same experience as looking into the famous GitHub / GitLab sites. Later for the first time, came to know that there are many open-source projects that are hosted in their system and made publicly available.   Edit: Let's take the examples of these projects for this article. libcamera - An open-source camera stack project dedicated to Linux systems. They hosted the complete source code on their host. They did not host on popular sites like GitHub, or GitLab. source code: https://git.libcamera.org/libcamera/libcamera.git/ Later came to know about the source code hosts by FFMPEG, VLC Media Player also follows a similar style of hosting and some orga...
