ffmpeg, python3: include executable

[T-Dynamos]

Closes #3137

Notes:

• https://github.com/agnostic-apollo/Android-Docs/blob/master/site/pages/en/projects/docs/apps/processes/app-data-file-execute-restrictions.md#apk-native-library
• python binary is just 8KB
• ffmpeg binary is about 252K or around 0.25MB

Test code:

import subprocess

def run_process(cmd):
    res = subprocess.run(cmd, capture_output=True, text=True)
    print(res.stdout)
    print(res.stderr)

import os
import sys

print(sys.executable)

# test python
run_process(["python", "--version"])
run_process(["python", "-m", "this"])

# test ffmpeg
run_process(["ffmpeg", "-version"])
run_process([
    "ffmpeg",
    "-f", "lavfi",                 
    "-i", "testsrc=size=128x128:rate=30",
    "-t", "2",                      
    "-c:v", "mpeg4",                
    "-f", "null",                   
    "-"
])

Expected Output:

Are you still working on this ?

Are you still working on this ?

Not really, I still have to add docs for this PR. Currently not working on this (busy on other stuff)

You can take over this if you want. :D

[kuzeyron]

Ah okay!

[kuzeyron]

LGTM! Great work with this one as it makes sure for future packages to be accessible without any hacks.
