  2 février 2020, par Eric Feillant

  I have compiled ffmpeg 4.2.2 and it gives me a segmatation fault after a while and i don’t knw why, i put it the request and a part of the debug log file.
  My ffmpeg request :
  /usr/local/bin/ffmpeg -loglevel debug -use_wallclock_as_timestamps 1 -rtsp_transport tcp -i "rtsp ://root:My_PW@My_IP_Address:5541/live.sdp" -f image2 -loop 1 -i ./overlay_score_160.png -i ./partenaire.png -filter_complex ’overlay=x=2:y=1,overlay=(main_w-overlay_w)/2:y=1’ -framerate 25 -crf 18 -preset veryfast -g 50 -vcodec libx264 -acodec copy -f flv rtmp ://localhost/hls/stream1 -async 1 -vsync 1 2> debug.txt

  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'

  


  



  Disclaimer : I went through the link https://www.wikihow.com/Install-FFmpeg-on-Windows but the URL is blocked by the IT team

  FFMPEG works only in developer mode. When I compile my jar program it returns the following error

  This is where it gets complicated. You can observe the messages that FFMPEG returns to me when I launch my program compile in jar :

  > [h264 @ 0000017c43e5b700] error while decoding MB 58 6, bytestream -14

  > 0000017c43e49d80] decoding for stream 0 failed

  This is the java code which thanks to the ProcessBuilder will launch FFMPEG :

  String urlVideoMp4 = movie.getPath().replace(".h264", ".mp4");
  
  
  
  File videoFinal = new File(urlVideoMp4);
  
  //checking if new video exists : if not, creating it with FFMPEG
  
  
  
  LOG.info("moviePath : " + movie);
  
  ProcessBuilder processBuilder = new ProcessBuilder(FFMPEG, "-framerate", "60", "-r", "120", "-i", movie.getPath(),"-c:v", "copy", urlVideoMp4);
  
  LOG.debug(processBuilder.command());
  
  
  
  processBuilder.inheritIO().start().waitFor();
  
  
  
  return videoFinal;
