• 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

  


• FFMPEG - make a stable & zero-padded frame counter

  2 octobre 2020, par L0Lock

  I use FFMPEG to print a frame counter on my videos, but I have two issues :

  


  

  


  

  1. The text stutters

  


  2. I'd like to have the possibility to have the number zero-padded (I.E. write 001 002 003 instead of 1 2 3).

  


  


  Code :

  


  @echo off
:again

cd /D %~p1

ffmpeg ^
    -i "%~nx1" ^
    -vf "drawtext=fontfile=arialbd.ttf: text='Frame \: %%{n}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: fontsize=40: box=1: boxcolor=black@0.4: boxborderw=8" ^
    -c:a copy ^
    "%~p1%~n1_framenumbered.mov"
if NOT ["%errorlevel%"]==["0"] goto:error
echo [92m%~n1 Done![0m

shift
if "%~1" == "" goto:end
goto:again

:error

echo [93mThere was an error. Please check your input file or report an issue on github.com/L0Lock/FFmpeg-bat-collection/issues.[0m
pause
exit 0

:end

cls
echo [92mEncoding succesful. This window will close after 10 seconds.[0m
timeout /t 10


  


  Solutions :

  


  

  • use `text='Frame : %eif:n:d:3' to get the zero-padded frame count (thanks to this answer)

  


  • use a monospace font (courrier new is common on Windows)

  


  • the script was failing to load the font, use the full path instead but without the drive (thanks to this answer) :

    

    • Do : /Windows/Fonts/courbd.ttf

    


    • Don't C:/Windows/Fonts/courbd.ttf nor use \

    


    


  


  


• Error while saving RTSP to .mp4 from a Hikvision using cvlc, openRTSP or ffmpeg

  4 octobre 2020, par Rui Martins

  I'm trying to save an RTSP streaming from a hikvion camera to a .mp4 file in a USB pen drive in a raspberry pi 3.

  


  I'm using raspbian, I read a lot from the internet, and I'm using different programs to try to save the video.

  


  I used cvlc, openRTSP and ffmpeg, and all of them have errors...

  


  Some commands that I used :

  


  openRTSP -D 1 -c -B 10000000 -b 10000000 -4 -Q -F video_openRTSP_ -P 1200 -w 1920 -h 1080 -f 25 -t -u admin xxxxx rtsp://admin:xxxxx@192.168.1.64:554/h264/ch1/main/av_stream


  


  ffmpeg -i rtsp://admin:xxxxx@192.168.1.64:554/h264/ch1/main/av_stream -acodec copy -vcodec copy ffmpeg.mp4


  


  cvlc --rtsp-tcp rtsp://admin:xxxxx@192.168.1.64:554/h264/ch1/main/av_stream --sout=file/mp4:cvlc.mp4 --stop-time=900 vlc://quit


  


  I tried a lot of different parameters for each one of these 3 programs... The final result never was good. I guess the Hikvision firmware is not implementing well the RTSP protocol...

  


  Exists some alternative firmware for Hikvision cameras ? As we have openWRT and ddWRT for routers ?

  


  Someone had the same problem as me ?

  


  (I want to store at least 15 minutes, even when the .mp4 file is saved, sometimes only save few seconds of videos, and sometimes I can't reproduce the video)
