![]() ![]() Therefore, to change 1 point of the image, we need to change 3-4 components (this is usually 3-4 bytes). Each point consists of 3 or 4 components, usually Red, Green and Blue signals, and sometimes there is an Alpha channel. To begin with, remember that the images consist of rows and columns of points, which are called pixels. Today we will learn how to quickly and dirty make such applications without knowing how to encode the video in general. Write a full application that decompresses the video stream, imbues the image with new elements or changes the image itself, and then compresses the stream anew, somewhat difficult. Sometimes we need to somehow filter the video, maybe put some text or graphic on top. Just add reading data from your sensors and your task completed. You can use ass-renderer for reference how to add text on image. Other way: write custom filter to ffmpeg. Then just grab video from your screen and broadcast to youtube or any other service. One possible way: write web-application, which will display video stream in your browser, loads data from sensors and display funny overlay. Now try to find/write software, which will be use it. It very hard to find open protocols with needed functionality.Īt this point I guess, you found any appropriate protocol. If you creating own system with micro-controllers, try to find usable and open protocol for data. ![]() This question a bit similar to I'm trying to add guitar tabs to a music video, do you know any software to do it?Īt first, in which format your data, which protocol used from your sensors? I guess, here some closed-source software and proprietary protocol for there sensors? Obviously, you need software which can read this data format/protocol. ![]()
