  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

  • process statuse is sombi after kill the process that opened in python subprocess.Popen and killed by subprocess.kill

    13 décembre 2018, par Eliya

    I’m using python with subprocess.Popen() to start FFmpeg with input live radio streaming URL and makes wav file every 30 seconds.
    When I try to kill the process with subprocess.kill() it works, But the process is still write in /proc/ and if I check-in system monitor the status of the process is "Zombi".

    Until the python script is done, So the process removed from /proc and I don’t see it in the system monitor.

    How can I kill the process without closed the python script ?

    here is example

    #! /usr/bin/python3 
    
import os
    
import subprocess
    
import time
    

    
# Start ffmpeg in background.
    
folder_name = "path_to_file"
    
input_ = "https://kanlivep2event-i.akamaihd.net/hls/live/749629/749629/kanmoreshet_mp3/chunklist.m3u8"
    
ffmpeg_cmd = [
    
        "ffmpeg",
    
        "-y",
    
        "-loglevel", "8",
    
        "-thread_queue_size", "1500",
    
        "-i", input_,
    
        "-c", "copy",
    
        "-vn",
    
        "-f", "segment",
    
        "-segment_time", "30",
    
        "-ar", "8000",
    
        "-acodec", "pcm_s32le",
    
        "-ac", "1",
    
        "-strftime", "1",
    
        str(folder_name + '/' + input_.replace("/","") + '_*_*_%s.wav')
    
    ]
    
process = subprocess.Popen(ffmpeg_cmd)
    
# Check if the process is exist
    
def check_exist(process):
    
    print("pid - ", process.pid)
    
    if os.path.isdir("/proc/{}".format(process.pid)):
    
        print ("Yes")
    
    else:
    
        print("No")
    

    
check_exist(process)
    
process.kill()
    
time.sleep(20)
    
check_exist(process)

  • Get total duration of multiple video files ? [duplicate]

    16 novembre 2018, par Soyal7

    This question already has an answer here :

    I want to extract video duration metadata from every video file in a specified directory and then sum all and view the total time in desktop app.

    I need to extract data from as much as hundreds of videos overall. In Windows I can view the total duration for many files manually when selecting them in the explorer and going into details. For 1500 mp4 files it takes about 20 seconds to make the calculations and view the total time. It’s much faster then what I’m currently getting when iterating with FFprobe.

    for filename in dirFiles:
    
   print(subprocess.check_output(['ffprobe', '-i', filename, '-show_entries','format=duration', '-sexagesimal' ,'-v', 'quiet', '-of', 'csv=%s' % ("p=0")]))

    What is the faster way to do this ?

  • Get duration from multiple video files ?

    22 mai 2022, par Soyal7

    I want to extract video duration metadata from every video file in a specified directory and then view the total duration.

    



    I need to extract the data from as much as thousands of videos overall. In Windows I can view the total duration for many files manually when selecting them in the explorer and going into details. For 1500 mp4 files it takes about 20 seconds to make the calculations and view the total time. It's relatively much faster then what I'm currently getting when iterating with FFprobe.

    



    How fast I am currently getting the result with FFprobe.

    



    for filename in dirFiles:
   print(subprocess.check_output(['ffprobe', '-i', filename, '-show_entries','format=duration', '-sexagesimal' ,'-v', 'quiet', '-of', 'csv=%s' % ("p=0")]))


    



    What is the faster way to do this ?
