  • Adding audio to an OpenCV video

    21 février 2019, par pcrunn

    I’m trying to make a script that automates the process of making a video and i’m stuck on the part that i add the audio, I’m not sure if i’ll need to use ffmpeg for that and if so, i’m not sure how to use it the proper way to work with OpenCV (Which I use for rendering the video).

    Thanks for your time, Here is my current code (that I found from a website)

    # Creating the video... The worst part. Literally
    

    
width = 1920
    
height = 1080
    
FPS = 30
    
length = 0
    

    
for song in songs:
    
    length+=song.info.length
    

    
length = int(length)
    

    
fourcc = VideoWriter_fourcc(*'MP42')
    
video = VideoWriter('result.avi', fourcc, float(FPS), (width, height))
    
for _ in range(FPS*length):
    
    frame = np.random.randint(0, 256,
    
                              (height, width, 3),
    
                              dtype=np.uint8)
    
    video.write(frame)
    

    
video.release()

  • Downloading, transcoding, then streaming on the fly with VLC

    12 avril 2012, par Alexis K

    I need to download a file from a web service the immediatley extract the audio, then transcode it, then stream it out.

    When I use :

    vlc.exe URL :sout=#transcode{acodec=mp3,ab=128,channels=2,samplerate=44100}:http{dst=:8080/audio.mp3}

    it is really choppy when I listen to it on the other computer. What is strange also is that for some YouTube links, the above works well, but for others it dosen't work well. I am not sure why this is.

    However, when I download the audio first, then stream it out, like this
    vlc.exe "song.mp3" :sout=#transcode{acodec=mp3,ab=128,channels=2,samplerate=44100}:http{dst=:8080/audio.mp3}

    it works well. The issue is I can't always download the song before hand (long pod casts or internet radio...).

    Is there a command or VLC optimization that I can use to help remedy this situation ? Or another program that would be good ?
