Preview of On Device Encoding

Background

Video encoding is heavy CPU task
At the moment, almost all the users' videos are being encoded by 3Speak Infrastructure
This is more of a centralised solution
3Speak would like to shift to decentralised solution

Current Solution

3Speak already has implemented decentralised and many Beta users are testing our Decentralised solution
I've already talked about setting up video encoder node which is part of it

WHY PART

No solution is perfect.
Everything is we do - is a journey towards - excellence & perfection.
At the moment, there are some challenges in current solution which is rolled out for beta users.
I, as an individual, want to explore entirely different approach
I call that approach - On-device-video encoding.
AGAIN - BUT - WHY?
I want our users as independent as possible.
User should be able to encode their own video
User should be able to self-host their own video
User should be able to use their own infrastructure
With this solution, I want to give power back to the community
I want to empower individual members

What is On-Device-Encoding?

You can use your mobile-device to encode your own video.
I am sure you must have tried many apps like these
If not, you can try searching for "Video compression" on AppStore or PlayStore.

For whom

This solution is for those who wants to encode their own video
Upload on their own (self host)
And publish without relying on 3Speak infrastructure or 3Speak Video Encoders
To be precise, For those who don't want to wait for their video to be encoded by others.

Okay but tell me HOW.

Everything I do is open source.
HOW part is done by code & it's available to read on the github.
Code is at the moment commented out (because it's not production ready)
Here is the link to the experimental code

Give me Explicit code.

    var pathToEncoding = '${externalDir.path}/encoding';
    var encodingDirPath = Directory(pathToEncoding);
    var exists = await encodingDirPath.exists();
    if (exists) {
      await encodingDirPath.delete(recursive: true);
    }
    var encodingDir = await Directory(encodingDirPath.path).create();
    var encoding480Dir = await Directory('${encodingDir.path}/480').create();
    var encoding720Dir = await Directory('${encodingDir.path}/720').create();
    var encoding1080Dir = await Directory('${encodingDir.path}/1080').create();
    var resultOf480Resize = await FFmpegKit.execute(
        "-i ${file.path} -vf scale=480:-1  ${encoding480Dir.path}/output.mp4");
    log('480 done');
    var resultOf720Resize = await FFmpegKit.execute(
        "-i ${file.path} -vf scale=720:-1 ${encoding720Dir.path}/output.mp4");
    log('720 done');
    var resultOf1080Resize = await FFmpegKit.execute(
        "-i ${file.path} -vf scale=1080:-1 ${encoding1080Dir.path}/output.mp4");
    log('1080 done');

What language? - It's DART programming language
Which Library? - FFmpeg for flutter
Of course, code written above is NOT perfect
I want feedback from community.
Those who have knowledge, I request them to guide me to accomplish this task

NOOO ! I don't want to use mobile. I want to use DESKTOP.

Okay Cool. I get that your mobile is something you don't want to use for video-encoding.
Just download Android Emulator (available for any operating system)
Install app
Start encoding video on your DESKTOP - Problem solved.

Okay. Video encoded. What's next?

Once we have a valid solution working for On Device Video Encoding,
I would like to switch to self-hosting.
