I recently purchased the AGPTEK M6 MP3 player (excellent, by the way), and I already own a RUIZU X52 as well. These players support some interesting features like video, text, and images, but they require specific encoding to work, otherwise they will show a format error. So I build a couple tools to make it easier to do!

#1: mp3c

mp3c is a device-specific file converter that supports audio, video, images, and text. It will take any format and convert it for each dedicated device profile. For example, the same video can be converted for both players (320x240, and 128x128), with all the necessary rotation and padding done automatically. It can convert e-books and images of any type as well.

#2: ytdlmp3

Similar to the first project, but it's centered around downloading YouTube videos from a certain recent time frame (last 2 weeks) so that you can always get the latest videos for offline YouTube watching/listening.

If you want to use these programs, you might need to build your own converter script in the converters folder. It's easy to do, it's just a simple FFMPEG command and a file extension name. You can make it highly specific to your player to get the best quality.

These projects are a little technical, so I'm sure most people won't have a good use for this. But if you are experiencing with the command line or Linux, you should have an easy time with this.

A docker file is also included so you can get this up and running on any machine, even Windows and Mac (not tested yet, but theoretically it should work perfectly).

Really enjoying my new player, just wanted to share what I've been working on!
