How to fix broken MP4 Videos for free

 if you have any broken mp4s, such as mov atom missing from your phone/camera/card dying during recording..


This gnu v2 app works Awesome!

I used it a few days ago to repair a video from a drone that was corrupted


I have a paid app on my android that I was using but it couldn't figure out the drone video so I had to find an alternative, this one worked much better


I used an Ubuntu virtual machine and followed the instructions on that page and fixed my video.

 If you get

./mp4grep/bin/mp4grep: error while loading shared libraries: libvosk.so: cannot open shared object file: No such file or directory

You probably need to run ldconfig on the folder containing libvosk

in my case it was

sudo ldconfig /home/nate/.local/lib/

I wrote a python program to put a taskbar icon with the CPU IDLE Percentage over time.

Lots of this is copied from stackoverflow of course..

This is what it looks like: 


from infi.systray import SysTrayIcon
from PIL import Image, ImageDraw,ImageFont
import time
import psutil
import threading
import wx
import wx.adv
import datetime
from wx.lib.embeddedimage import PyEmbeddedImage

def background():
while True:
uptime = time.time() - psutil.boot_time()
global idle_ratio
idle_ratio = psutil.cpu_times().idle / psutil.cpu_count() / uptime * 100
d = uptime // (24 * 3600)
uptime = uptime % (24 * 3600)
h = uptime // 3600
uptime %= 3600
m = uptime // 60
uptime %= 60
s = uptime
print(idle_ratio)
time.sleep(10)
if stop_threads:
break
global stop_threads
stop_threads = False
# print(f"Uptime: {d:n}d {h:02n}:{m:02n}:{s:02n} - Idle Ratio: {idle_ratio:02.2f}%")


b = threading.Thread(name='background', target=background)
print("starting thread")
b.start()
print("\nIdle ratio:")
print(idle_ratio)
#
# A white box 28x28 pixels

# Use current time as text, for want of something useful
