Well for instance you can use it to apply tranparencys or other effects using the geq filter. It applies a formula to every pixel in the input and can adjust alpha, rgb values, and gamma. You can also use conditionals in your formula and have access to the current pixels location and value, so you can apply your transforms only to specific regions if you want, or do an adjustment keyed only to a specific color.
I love you ffmpeg
Its insane just how important it is and the vast majority of the world doesn’t even know it exists. Truly unsung heroes (everyone who works on it).
I’m surprised nobody posted the xkcd comic. I think Randall had ImageMagick in mind (he names it in the alt text) but it applies to ffmpeg as well.
I always used to think about curl when I see that comic. Maybe less important in recent years but still a corner stone.
Curl is less important in the cloudverse?
Ffmpeg has been such cool software to learn. Simple filter chains can do incredible things
Please, go on!
