After googling... It's a video codex

To accomplish this task, I decided to try out the new Strands Agents SDK. It's a fairly new framework for building agents that has a simple way to define tools that the agent can use to assist in responding to prompts. For this solution, we'll need FFMPEG and Whisper installed on the machine where the agent runs. I'll be working locally, but this could easily be converted to a server-based solution using FastAPI or another web framework and deployed to the cloud in a Docker/Podman container.

Extraer fotogramas: Una clase VideoProcessor que utiliza la biblioteca ffmpeg libavcodec para procesar video y crear fotogramas a intervalos de un segundo (personalizable a través de la configuración de FPS).

Extract frames: A VideoProcessor class that uses the ffmpeg libavcodec library to process video and create frames at one-second intervals (customizable through FPS settings).

Intrinsics have the disadvantages of asm (non-portable) but also don't reliably have the advantages of them (compilers are pretty unpredictable about optimizing with them) and they're ugly (especially x86 with its weird Hungarian stuff).

There is just a little bit of intrinsics code in ffmpeg, which I wrote, that does memory copies.

It's like this because we didn't want to hide the memory accesses from the compiler, because that hurts optimization, as well as memory tools like ASan.

Still no HEIC. Let's get the latest build from master. I have installed: ffmpeg-2024-10-24-git-153a6dc8fa-full_build.7z after having checked SHA256. Still no HEIC. Let's check the github of ffmpeg and it seems that HEIC is not listed in the ffmpeg image formats HEIC is not supported...read the manual before diving into the implementation.

This gave me the full video on my hard drive. There is also a feature in yt-dlp to download a certain time segment of a video but it seemed unreliable and I also have to use ffmpeg to add intro and outro videos in any case.

Fortunately, you don’t always need to go to so low level of abstraction when you develop GIF encoding in your app. One of the most popular libraries for image/video encoding is FFmpeg. Android developer-friendly version is not provided officially. However, some wrappers do exist. At the time of writing one of the most popular is Mobile FFmpeg. Something like this will be probably all you need when you just want to produce GIF out of some input source.

There are many methods how we can solve this problem. But here, I would like to tell you about FFmpeg. It is a free and open-source tool available for all major operating systems. FFmpeg is fast and gives good results in compression, changing formats, and resolution.
