  • Run FFMPEG within python [on hold]

    10 juillet 2019, par Awais

    I’m making a program which allows you to download videos with m3u8 links, I can’t do it manually as I don’t possess the skills. So I thought maybe I could use FFMPEG to carry out the task for me.
    How would I be able to run FFMPEG by using a module, such as subprocess, if they are in the same directory as the main.py file ?

    I’ve already looked up how to do it but none of the answers provide an explanation of the code or don’t explain where the output will be received.

    import subprocess
    

    
answer = input "enter m3u8 link"
    
output = input "enter the name for the video"
    

    
Commands = ['ffmpeg', '-i', url, '-c', 'copy', answer, output + '.mp4']
    

    
subprocess.call(Commands, shell=True)

    Is this how I should come around it ?

    I’ve also wondered if you could run command prompt as an admin directly from python and carry out functions as if you were on there. This would help carrying out the tasks.

    Any help/suggestion is appreciated

  • Building static OpenCV with ffmpeg is still looking for shared libavcodec

    5 janvier 2016, par Romanzo Criminale

    I’m trying to build a static OpenCV Python with ffmpeg enabled to run on AWS Lambda. I Need to upload OpenCV my cv2.so in a zip file.

    To do so I set the BUILD_SHARED_LIBS=OFF and WITH_FFPMEG=YES. But when doing import cv2 in the Python shell, I get the error :

    ImportError: libavcodec.so.53: cannot open shared object file: No such file or directory

    If I set WITH_FFPMEG=NO I don’t get this error anymore but I need ffmpeg to read a video.

    What I would like to do is OpenCV to use the static libavcodec library not the shared one. I thought setting up BUILD_SHARE_LIBS to off would be enough but it’s not. T

    here are no flags in the cmake file which let you specified the path to libavcodec. I’ve been looking for sometimes but I can’t find a solution.

    Any ideas ?

  • Using ffmpeg with Imagick

    19 mars 2014, par user3240613

    I am trying to generate thumbnails from videos in imagick, by extracting a single frame from them, using the ffmpeg application.

    I use this code currently :

    $image->newPseudoImage( null, null, 'ffmpeg:video.mp4[50]');

    It works. But it is not an ideal solution.
    I want to generate the thumbnail from a 50% position in the video, but i do not know how long the video is, so I can't do something like ffmpeg:video.mp4[500001]. And even if I knew the length, I still couldn't do it because running this ffmpeg:video.mp4[1000] takes almost 20 seconds to execute (ffmpeg:video.mp4[50] takes one or two seconds only).

    When i try to add some extra parameters like "ffmpeg:video.mp4[50] -ss 50" it returns error.

    The only other option I can think of, is using the exec to directly execute the ffmpeg command in the shell like "ffmpeg -i video.mp4 -vframes 1 -o screenshot.jpg" or something like that. Would that actually be more efficient solution than using the newpseudoimage method ?
