• Everytime I run my code ffmpeg responds with this instead of doing its function. How do I fix ?

  Everytime I run the code it does this.

  


  code :

  


  import praw

from pydub import AudioSegment

def download_video(url, filename):
    response = requests.get(url)
    with open(filename, 'wb') as f:

    # Cleaning up temporary files
    os.remove("combined_audio.mp3")

def main():
    reddit = praw.Reddit(
       client_id='XXX',
        client_secret='XXX',

    )
    
    subreddit_name = input("Enter the name of the subreddit: ")

    subreddit = reddit.subreddit(subreddit_name)
    submissions = subreddit.hot(limit=limit)
    
    video_urls = [submission.url for submission in submissions if submission.media and 'reddit_video' in submission.media]
    
    if video_urls:
        output_filename = input("Enter the output filename (e.g., output.mp4): ")
        combine_videos(video_urls, output_filename)
        print("Videos combined successfully!")
    else:
        print("No Reddit videos found in the subreddit.")

if __name__ == "__main__":
    main()


  


  Anyone got any idea why this happens ?

  


  I'm making a script that scrapes videos from a specific subreddit.

  


  Also if it helps the temp video file is corrupted when it gets made.

  


  I've put this into chatGPT as well and brought an expert friend and he hasn't been able to help me.

  


• cannot link ffmpeg libraries for my own Qt project

  14 août 2013, par Dan T

  EDIT : Question solved (see bottom)

  I have spent MANY hours searching for a solution to my problem, but have not managed. I am on OSX and trying to link ffmpeg to my own Qt project. I have tried to do the simplest thing possible but even this does not work :

  After gettings yasm and x264 installed, I ran
  ./configure —enable-static —enable-gpl —enable-libx264 and then
  make && make install

  ffmpeg runs fine when I then try to run it on the command line. I then just set up a simple project in the ffmpeg directory with the following ffmpeg.pro file :

  TEMPLATE = app
  
  
  
  QT += core
  
  
  
  INCLUDEPATH += /usr/local/include
  
  LIBS += -L/usr/local/lib
  
  LIBS += -lavdevice -lavfilter -lavformat -lavcodec -lpostproc -lswresample -lswscale -lavutil -lpthread -lbz2 -lm -lz -lx264
  
  
  
  HEADERS += ffmpeg.h
  
  
  
  SOURCES += ffmpeg.c

  I'm not sure whether I need all those libraries, but they were all the .a files that ffmpeg created. When I try to build the project (as is), I get the following linker error :

  g++ -headerpad_max_install_names -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 -o ffmpeg.app/Contents/MacOS/ffmpeg ffmpeg.o -F/Users/dtamayo/QtSDK/Desktop/Qt/4.8.1/gcc/lib -L/Users/dtamayo/QtSDK/Desktop/Qt/4.8.1/gcc/lib -L/usr/local/lib -lavdevice -lavfilter -lavformat -lavcodec -lpostproc -lswresample -lswscale -lavutil -lpthread -lbz2 -lm -lz -lx264 -framework QtGui -L/usr/local/pgsql/lib -L/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib -F/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib -framework QtCore

  EDIT :

  Thank you very much for your quick responses. I'm embarrassed to say that with the help of a friend I found the problem, so I'll add the solution here in case there are others as inept as I am that run into the same issue !

  The problem is that I hadn't added the following source files to the project, which do not get built as part of one of the ffmpeg libraries :

  cmdutils.c ffmpeg_filter.c ffmpeg_opt.c

  In addition, I had to add usr/lib to my library path, and add the library -liconv.
