    On ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...

    On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

  • ffmpeg command working from command line but not from python subprocess.Popen

    7 novembre 2017, par Stuart Clarke

    I’m trying to run the below command from within a Python script.

    ffmpeg -y -loglevel verbose -i /var/www/Intro30.mp4 -i /var/www/temp/videoHD.mp4 -i /var/www/Credits30.mp4 -filter_complex '[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1 [v] [a]' -map '[v]' -map '[a]' /var/www/temp/merged.mp4

    But it results in a corrupted file. This is the output.

    Some lines removed to keep under the line limit.

    Here is the python method I use to execute the ffmpeg lines.

    def ffmpeg(args):
    
    err = None
    
    command = [
    
        ffmpegcmd, '-y',
    
        '-loglevel', loglevel
    
    ] + args
    
    ffmpeg = subprocess.Popen(command, stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
    
    while err == None:
    
        out, err = ffmpeg.communicate()
    
        time.sleep(1)
    
    if err:
    
        print(" ".join(command))
    
        raise Exception(err)

    *Edit

    When ever I need to use a command that requires single quotes around the arguments i.e. '[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1 [v] [a]' the above function wouldn’t work. So I made another function for those case which deals with the command as a string. Here is is.

    def ffmpegStr(args):
    
    err = None
    
    command = [
    
        ffmpegcmd, '-y',
    
        '-loglevel', loglevel
    
    ] + args
    
    commandStr = " ".join(command)
    
    print(commandStr)
    
    ffmpeg = subprocess.Popen(shlex.split(commandStr), stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
    
    while err == None:
    
        out, err = ffmpeg.communicate()
    
        time.sleep(1)
    
    if err:
    
        print(commandStr)
    
        raise Exception(err)

    As you can see I’ve added a print to see what is being handed to the subprocess.Popen function. This is the method that is being used when the ffmpeg command does not run as expected.

    I use ffmpegcmd as a variable so that I can change the ffmpeg version if needed in both functions with 1 change.

    The args is just the list of arguments specific to what I want ffmpeg to do.

    I also like to have the option of changing the loglevel in both functions with 1 line and so use a variable for this.

    *End Edit

    Why the difference in how it is handled ?

    Cheers,

    Stu

  • How to turn an AppleScript path into a posix path and pass to shell script ?

    18 mars 2017, par Björn

    I´m trying to create a textfile that my ffmpeg-command can use to merge two videofiles. The problem I´m having is getting my folder/file-paths to look like I want. The two lines that cause my problems are :

    set theFile to path to replay_folder &amp; "ls.txt"

    I simply want this path to be the path of replay_folder and ls.txt

    In the shell script line I want the same thing.

    do shell script "cd " &amp; replay_folder &amp; "
       /usr/local/bin/ffmpeg -f concat -i ls.txt -c copy merged.mov"

    I get this path with the shell script Macintosh HD:Users:BjornFroberg:Documents:wirecast:Replay-2017-03-17-12_11-1489749062:

    But I want this /Users/BjornFroberg/Documents/wirecast/Replay-2017-03-17-12_11-1489749062/

    The full code is :

    tell application "Finder"
    
set sorted_list to sort folders of folder ("Macintosh HD:Users:bjornfroberg:documents:wirecast:") by creation date
    
set replay_folder to item -1 of sorted_list
    
set replay_files to sort items of replay_folder by creation date
    
end tell
    

    
set nr4 to "file '" &amp; name of item -4 of replay_files &amp; "'"
    
set nr3 to "file '" &amp; name of item -3 of replay_files &amp; "'"
    

    
set theText to nr4 &amp; return &amp; nr3
    

    
set overwriteExistingContent to true
    

    
set theFile to path to replay_folder &amp; "ls.txt" --actual path is: POSIX file "/Users/BjornFroberg/Documents/wirecast/Replay-2017-03-17-12_11-1489749062/ls.txt"
    

    
set theOpenedFile to open for access file theFile with write permission
    

    
if overwriteExistingContent is true then set eof of theOpenedFile to 0
    

    
write theText to theOpenedFile starting at eof
    

    
close access theOpenedFile
    

    
do shell script "cd " &amp; replay_folder &amp; "
    
/usr/local/bin/ffmpeg -f concat -i ls.txt -c copy merged.mov"

    Any help is appreciated :)
