• NGINX RTMP Server - Continuity replacement of track

  6 janvier 2023, par sweetngx

  I broadcast my video archive as live streaming with FFMpeg or similar applications. But since there are multiple videos, ffmpeg reconnects with the rtmp server in each new track, and while watching the live stream, the connection naturally terminates in each video transition and I continue watching by reconnecting to rtmp. What I want to do is that when ffmpeg switches to each new track, the rtmp server does not terminate my connection and continues the new video stream without interruption, that is, in flow changes, the rtmp server can wait for the new flow for a while and continue where it left off. I actually tried to do this using wait_video but it is not efficient and stable enough. How do you think I can solve this problem ? Should I solve it on the FFMpeg side or should I solve it on the Rtmp Server side ? All my videos have the same resolution and codec properties

  


• Save generated image to ImageField model Django

  Detected path traversal attempt in '/home/mrlonely/Desktop/lumen/lumen/media/thumbnail/6.jpeg'

  


  


  When i run this in the views.py :

  


  def generate_thumbnail(instance):
   post = Post.objects.get(pk=instance.pk)
   output = 'media/thumbnail/' + post.title + '.jpeg'
   filename_thumbnail = Path.joinpath(filename, output)  
   try:
      (
            ffmpeg
            .input(str(filename)+post.video.url, ss='00:00:20')
            .output(output, vframes=1)
            .overwrite_output()
            .run(capture_stdout=True, capture_stderr=True)
        )
      with open(filename_thumbnail, 'rb') as file_handler:
         django_file = File(file_handler)
         post.thumbnail.save(filename_thumbnail, 'thumbnail/')
   except ffmpeg.Error as e:
        print(e.stderr.decode(), file=sys.stderr)
        sys.exit(1)


  


  I am trying to connect the ffmpeg generated thumbnail to the model ImageField on the Post model (instance is post)
