• GUI Development using Eclipse, PYQT , QT designer tools in Linux for the c shell scripts written in Cygwin [on hold]

  9 octobre 2014, par user2658684

  I have written a c shell script that used the audio libraries such as ffmpeg and sox. In the script I have also called the python scripts. I have done this using CYGWIN and for that I had installed the ffmpeg, sox, python etc in cygwin environment.

  Now I want this to be transferred to LINUX machine that has centos 7.0 installed and develop the GUI for this. I have installed eclipse on it with Pydev and am trying to develop the GUI using PyQt and QT designer tools. Please suggest me if there is audio processing libraries like ffmpeg, sox available for eclipse PYdev.

  Also if some one can give me better suggestion of environment that I can use to develop the GUI other that Eclipse so that it is easier to use all the libraries in the environment.

• Python subprocess.Popen + ffmpeg breaks terminal input

  16 décembre 2020, par Barney Suit

  I was writing a module to create random screenshots from a video and used subprocess.Popen to run multiple commands in parallel but this leads to terminal refusing from showing any input once the python program is finished running. But it still accepts most inputs given from the keyboard it just doesn't display it.

  


  Only if I type the reset command terminal starts working fine
This happened on ssh with putty and other ssh clients even ssh with powershell on windows and directly running on terminal with VNC

  


  But without ssh directly running the same command on windows ssh works fine and and inputs are visible

  


  here's a gif example for whats happening


  


  and code to replicate it

  


  #!/usr/bin/env python3.8
from subprocess import Popen

def create_screenshots():

    commands = ['ffmpeg -hide_banner -loglevel panic -ss 329  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.329.frame.png"',
                'ffmpeg -hide_banner -loglevel panic -ss 312  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.312.frame.png"',
                'ffmpeg -hide_banner -loglevel panic -ss 533  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.533.frame.png"',
                'ffmpeg -hide_banner -loglevel panic -ss 444  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.444.frame.png"',
                'ffmpeg -hide_banner -loglevel panic -ss 411  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.411.frame.png"',
                'ffmpeg -hide_banner -loglevel panic -ss 413  -i "/home/user/file.mkv" -y -vframes 1   "/home/user/file.413.frame.png"']
    screenshot_files = []
    processes = [Popen(command, shell=True) for command in commands]
    for process in processes:
        process.wait()
    
    return screenshot_files
