  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg.exe not detecting UScreenCapture

    14 janvier 2021, par TenG

    I have two version of ffmpeg on the Windows 7 PC.

    


    The first came installed with an application, which uses ffmpeg to capture video/audio of the desktop. This works.

    


    It uses an older version of ffmpeg, so I downloaded the latest version and tried the same command and it reports that the devices are not detected.

    


    Commands run :

    


    Old FFMPEG :

    


    ffmpeg.exe -list_devices true -f dshow -i dummy

  • How to queue ffmpeg jobs for transcoding ?

    25 juillet 2019, par sujit patel

    This scripts below check ftp fro any media file and starts transcoding using ffmpeg. Problem is it starts so many ffmpeg process simultaneously. since so many ffmpeg process running servers becomes too slow and takes heavy amount of time to transcodes videos. Sometimes server stops working.

    How to put jobs in a queue ?

  • ffmpeg with Popen (python) on Windows

    21 août 2018, par Gabrielle

    I am trying to use ffmpeg with Popen. The ffmpeg command I am trying works on cmd but gives me error with Popen.

    I am using the standalone ffmpeg .exe :

    ffmpeg -f gdigrab -offset_x 10 -offset_y 20 -show_region 1 -i desktop -video_size 1536x864 -b:v 2M -maxrate 1M -bufsize 1M -tune fastdecode -crf 15 -preset ultrafast -pix_fmt yuv420p -r 25 <path>/video.mov -qp 1 -y -an
    
</path>

    This gives me Invalid argument, but if I remove the last parameters in order to make the output the last thing on the string, I get a different error :

    Output file #0 does not contain any stream

    I tried to use -f dshow -i video="UScreenCapture" instead of the gdigrab, but both give me the same error with and without the parameters in the end.

    Both commands work on command line.

    On command line this ffmpeg -list_devices true -f dshow -i dummy returns this :

    [dshow @ 000001b24fa6a300] DirectShow video devices (some may be both video and audio devices)
    
[dshow @ 000001b24fa6a300]  "Integrated Webcam"
    
[dshow @ 000001b24fa6a300]     Alternative name "@device_pnp_\\?\usb#vid_1bcf&amp;pid_2b8a&amp;mi_00#6&amp;2c03619a&amp;0&amp;0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global"
    
[dshow @ 000001b24fa6a300]  "UScreenCapture"
    
[dshow @ 000001b24fa6a300]     Alternative name "@device_sw_{860BB310-5D01-11D0-BD3B-00A0C911CE86}\UScreenCapture"
    
[dshow @ 000001b24fa6a300] DirectShow audio devices
    
[dshow @ 000001b24fa6a300]  "Microphone (Realtek Audio)"
    
[dshow @ 000001b24fa6a300]     Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{35EBFC89-7B09-4557-8032-85AA0B688FE9}"

    But on popen I can’t check it :

    -list_devices true -f dshow -i dummy: Invalid argument

    For the python part of the code I am using this :

    p = subprocess.Popen([getPathForFile("windows/ffmpeg").replace('\\','/'),  " -f gdigrab -offset_x 10 -offset_y 20 -show_region 1 -i desktop -video_size 1536x864 -b:v 2M -maxrate 1M -bufsize 1M -tune fastdecode -crf 15 -preset ultrafast -pix_fmt yuv420p -r 25 -qp 1 -y -an "+ path.replace('\\\\','/').replace('\\','/')+"video.mov"], shell=True)

    The getPathForFile is a custom function that returns the path. this is correct, mainly because the errors I am getting are from the ffmpeg, so...

    I am on a Windows 10. FFmpeg 4.0. Python 3.5.

    Any ideas why am I getting these errors on Popen but not on command line and how to fix them ? (mainly the second error)
