• Revision bd9cd9a185 : fix superframe index marker masks The superframe index marker byte carries data

  13 mars 2013, par John Koleszar

  Changed Paths : Modify /test/superframe_test.cc Modify /vp9/vp9_dx_iface.c fix superframe index marker masks The superframe index marker byte carries data in the lower 5 bits. Only the upper 3 should be used as part of the mask to detect it. By masking with 0xf0, the previous code was incorrect (...)

• PyInstaller —noconsole still shows the console after running the app

  23 septembre 2020, par Kiren78

  I've built an app to download and play sound everytime someone inserts or removes USB drive from PC.
  
Code :

  


  from playsound import playsound
from win10toast import ToastNotifier
from time import sleep
from typing import Callable
import threading
import os
import youtube_dl
import win32file


def play_audio():
    try:
        path = os.getcwd() + "\\audio.mp3"
        ydl_opts = {
            'format': 'bestaudio/best',
            'postprocessors': [{
                'key': 'FFmpegExtractAudio',
                'preferredcodec': 'mp3',
                'preferredquality': '192',
            }],
            'outtmpl': path
        }

        with youtube_dl.YoutubeDL(ydl_opts) as ydl:
            ydl.download(['https://www.youtube.com/watch?v=_0HTwQjMr9k'])

        playsound(path)
    except Exception as e:
        toast = ToastNotifier()
        toast.show_toast("RIP prank failed byq", "no ogolnie prank failed rip co jest?", duration=20)


def get_drives():
    drive_list = []
    drivebits = win32file.GetLogicalDrives()
    for d in range(1, 26):
        mask = 1 << d
        if drivebits & mask:
            drname = '%c:\\' % chr(ord('A') + d)
            t = win32file.GetDriveType(drname)
            if t == win32file.DRIVE_REMOVABLE:
                drive_list.append(drname)
    return drive_list


def watch_drives(on_change: Callable[[dict], None] = print, poll_interval: int = 1):
    def _watcher():
        global prev
        while True:
            drives = get_drives()
            if prev != drives:
                on_change(drives)
                play_audio()
                prev = drives
            sleep(poll_interval)

    t = threading.Thread(target=_watcher)
    t.start()
    t.join()


if __name__ == '__main__':
    prev = get_drives()
    watch_drives(on_change=print)


  


  I don't understand it but everytime the download starts and FFmpeg starts debugging everything (using youtube-dl) a couple of console windows appear for a fraction of a second and they immediately disappear. How can I TOTALLY disable the console so that even FFmpeg can't open it ?

  


  EDIT : Yes, I've already tried using --windowed and -w parameters in PyInstaller

  


• Remove Black Frames from an overlayed Circled Video

  7 juillet 2017, par amanguel

  I have a video that I need to overlay on top of another video. The first video have parts with black frames that I don’t want to be overlayed and I also need to mask this video with a circle.

  In other words, I will be overlaying a few circled videos on top of a bigger rectangular video and I also don’t want to show black frames from the circled videos.

  Could you please help me.

  Thanks !!!!!
