  • I keep having the message "MovieWriter ffmpeg unavailable ; using Pillow instead." I want to save as MP4 an animation

    6 décembre 2023, par Enrra

    I am doing an animation :

    


    animation = FuncAnimation(fig, update, frames=len(time_values), interval=250, repeat=False)
with a simple frame update function, I want it save it as a MP4 format :

    


    animation.save(f'{save_path}/heat_map.mp4', writer='ffmpeg', fps=10)

    


    I get the error message "MovieWriter ffmpeg unavailable ; using Pillow instead."

    


    I tried to do the following :

    


    plt.rcParams['animation.ffmpeg_path'] ='C:\\ProgramData\\Anaconda3\\LIB\\site-packages\\ffmpeg'
FFwriter = animation.FFMpegWriter()
animation.save(f'{save_path}/heat_map.mp4', writer = FFwriter, fps=10)


    


    This gets me an error message :

    


    Traceback (most recent call last):&#xA;  File "Graph_V1-8.py", line 406, in <module>&#xA;    FFwriter = animation.FFMpegWriter()&#xA;AttributeError: &#x27;FuncAnimation&#x27; object has no attribute &#x27;FFMpegWriter&#x27;&#xA;</module>

    &#xA;

    and I also tried to do the following :&#xA;animation.save(f&#x27;{save_path}/heat_map.mp4&#x27;, writer=&#x27;ffmpeg&#x27;, fps=10, codec=&#x27;libx264&#x27;)

    &#xA;

    which also get me the error :&#xA;"MovieWriter ffmpeg unavailable ; using Pillow instead."

    &#xA;

    When I write :

    &#xA;

    pip install ffmpeg&#xA;Requirement already satisfied: ffmpeg in c:\programdata\anaconda3\lib\site-packages (1.4)&#xA;

    &#xA;

    Thank you in advance for your help

    Thanks for your help !

  • how use pipe instead of save method in fluent-ffmpeg ?

    27 juin 2019, par Mohsen Rahnamaei

    I gonna use fluent ffmpeg to write something on video
    I use this cod

    var proc = ffmpeg(req.filePath). videoFilters(
    
  {
    
    filter: 'drawtext',
    
    options: {
    
      text: 'VERY LONG TEXT VERY VERY VERY VERY LOL!!!',
    
      fontsize: 36,
    
      fontcolor: 'white',
    
      x: '(main_w/2-text_w/2)',
    
      y: '(text_h/2)+15',
    
      shadowcolor: 'black',
    
      shadowx: 2,
    
      shadowy: 2
    
    }}
    

    
)
    
// use the 'flashvideo' preset (located in /lib/presets/flashvideo.js)
    
.on('end', function() {
    
  console.log('file has been converted succesfully');
    
})
    
.on('error', function(err) {
    
  console.log('an error happened: ' + err.message);
    
}).save('/home/gheidar/Desktop/ffmpeg_test/rt.ts');

    and everything is correct
    but I want to export this output to stream for the response of the request
    means that I want to use pipe() instead of save method

    something like this :

    var proc = ffmpeg(req.filePath). videoFilters(
    
  {
    
    filter: 'drawtext',
    
    options: {
    
      text: 'VERY LONG TEXT VERY VERY VERY VERY LOL!!!',
    
      fontsize: 36,
    
      fontcolor: 'white',
    
      x: '(main_w/2-text_w/2)',
    
      y: '(text_h/2)+15',
    
      shadowcolor: 'black',
    
      shadowx: 2,
    
      shadowy: 2
    
    }}
    

    
)
    
// use the 'flashvideo' preset (located in /lib/presets/flashvideo.js)
    
.on('end', function() {
    
  console.log('file has been converted succesfully');
    
})
    
.on('error', function(err) {
    
  console.log('an error happened: ' + err.message);
    
}).pipe(res)

    its just change in the last line
    and I get this error :

    an error happened: ffmpeg exited with code 1: pipe:1: Invalid argument

    how can export this ffmpeg command to stream response ????
