  • FFMPEG : i need audio channels 7 & 8 to be the main audio track for a video

    10 avril 2013, par lo_fye

    I have a video with 8 channels of audio.

    I need tracks 7 (Left Stereo) and 8 (Right Stereo) to be the audio for the video (which I'm converting to flv).

    I've tried playing with -filter_complex and the join, amix, and amerge filters, as well as the -map parameter, but I can't seem to find the right combination of values :-/

    Output :

    /usr/local/bin/ffmpeg-1.0/bin/ffmpeg -i '/folder/video_name.mov' -f 'flv' \
    
-s '320x240' -b '250k' -aspect '4:3' -ac 1 -ab '64k' -ar '22050' -y \
    
/folder/video_name.flv

  • Reading file stream from Google Cloud Storage to ffmpeg (using fluent-ffmpeg)

    27 juillet 2018, par ekuusi

    I’m trying to run ffmpeg on a NodeJS backend with fluent-ffmpeg, reading input files from Google Cloud Storage. Everything works fine if I download the file first :

    const file = storage
    
    .bucket('example_bucket')
    
    .file('examplefile.mp4');
    

    
file.download({destination: 'test.mp4'}, (err) => {
    

    
    let command = ffmpeg()
    
    .input('test.mp4')
    
    .duration(10)
    
    .format('mp4');
    

    
    command.save('test_out.mp4');
    

    
});
    

    
res.json([{
    
    message: 'Command sent!'
    
}]);

    But if I try to use a readable stream as the input, it fails :

    const file = storage
    
    .bucket('example_bucket')
    
    .file('examplefile.mp4');
    

    

    
var filestream = file.createReadStream()
    

    
let command = ffmpeg()
    
    .input(filestream)
    
    .duration(10)
    
    .format('mp4');
    

    

    
command.save('test_out.mp4');
    
});
    

    
res.json([{
    
    message: 'Command sent!'
    
}]);

    Here is the full output of ffmpeg when trying to do the conversion. It seems to read the details of the file fine but for some reason it fails, saying "Cannot process video : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input"

    Spawned Ffmpeg with command: ffmpeg -i pipe:0 -y -t 10 -f mp4 test_out.mp4

    I am new to ffmpeg and i am facing this error for more then 2 days.
This ffmpeg command :
!ffmpeg -i "{fromPath}" -i "{toPath}" -filter_complex "xfade=transition={chosenTransition}:duration={transitionDuration}:offset=-1.5" -c:v libx264 -crf 18 -preset veryfast "{outPath}"
I run that previous command 3 times in row where output of the previous command is input that is getting produced as 15360 timebase video i guess.

    


    is giving me this error : "First input link main timebase (1/15360) do not match the corresponding second input link xfade timebase (1/90000)"

    


    So when i merge two of my videos the output is video with (1/15360) timebase. Original videos has (1/90000) timebase.

    


    Pls help what i wana archive is basicly multiple videos inside a folder called "clips" merge together using a random transition from xfade/ffmpeg.

    


    On colab i tried all this ways :

    


    !rm -rf chunks
!mkdir chunks
time.sleep(1)
folderPath = '/content/clips'
videoOutput = '/content/test.mp4'
transitionDuration = 6

videoFiles = [f"{folderPath}/{f}" for f in os.listdir(folderPath) if f.endswith('.mp4')]
random.shuffle(videoFiles)
fromPath = videoFiles[0]
toPath = ''
outPath = ''
transitions = ['fade', 'wipeup', 'slidedown', 'circleclose', 'radial' , 'hrslice', 'hblur', 'smoothleft', 'smoothright']

for videoIndex, videoName in enumerate(videoFiles):
    if videoIndex == 0:
        continue
    toPath = videoName
    chosenTransition = random.choice(transitions)
    print('chosenTransition', chosenTransition)
    clipDuration = int((imageio.get_reader(fromPath)).get_meta_data()['duration']) - transitionDuration
    # !echo -i /content/clips/clip0.mp4 -i /content/clips/clip1.mp4 -filter_complex xfade=transition={chosenTransition}:duration=3:offset={clipDuration} dissolveVideo.mp4

    if videoIndex == len(videoFiles) - 1:
        outPath = videoOutput
    else:
        outPath = f'/content/chunks/chunk{videoIndex}.mp4'
    time.sleep(2)
