  • FFMPEG video concatenation returning error : `Error reinitializing filters !`, `Invalid argument`, `Conversion failed !`

    2 février 2020, par PureStress

    I am attempting to concatenate .mp4 files. I am using fluent-ffmpeg and @ffmpeg-installer/ffmpeg Here is the pseudocode :

    let mergeClips = ffmpeg();
    
for (let i = 0; i < 5; i++) {
    
    await downloadVideo(newUrl, './testVideos/0/' + i + '.mp4');
    
    mergeClips = mergeClips.mergeAdd('./testVideos/0/' + i + '.mp4');
    
}
    
mergeClips.mergeToFile('compilation.mp4', './temp');

    This results in errors. The following is the command sent by fluent-ffmpeg :

    ffmpeg -i ./testVideos/0/0.mp4 -i ./testVideos/0/6.mp4 -i ./testVideos/0/14.mp4 -i ./testVideos/0/15.mp4 -y -filter_complex concat=n=4:v=1:a=0 ./testVideos/0/compilation.mp4

    When I run the command manually, I receive the following :

    PS C:\path> ffmpeg -i ./testVideos/0/0.mp4 -i ./testVideos/0/6.mp4 -i ./testVideos/0/14.mp4 -i ./testVideos/0/15.mp4 -y -filter_complex concat=n=4:v=1:a=0 ./testVideos/0/compilation.mp4

    Then i get "Segmentation fault" and ffmpeg exits

  • MovieWriter ffmpeg unavailable ; trying to use instead

    28 janvier 2021, par user6882757

    Is there any way to use moving plot without ffmpeg ?

    



    import matplotlib.animation as animation
from IPython.display import HTML

fig, ax = plt.subplots(figsize=(15, 8))
animator = animation.FuncAnimation(fig, draw_barchart, frames=range(1968, 2019))
HTML(animator.to_jshtml()) 
animator.save('dynamic_images.mp4')


    



    My code is above, I am getting the key error.mp4', ValueError: unknown file extension: .mp4

    



    I tried installing conda install -c conda-forge ffmpeg end up with SSL issue

    



      


    • Is there any way to use moving plot without ffmpeg

      • 


    • As like error throwing is there any way to use 'matplotlib.animation.PillowWriter'

      •
