• Force ffmpeg to ignore error when connecting failed

  2 avril 2015, par Given92

  I’m trying to deploy a live stream delivery system with nginx and nginx-rtmp-module.

  For every node in my system, I wish it could ’forward’ the live stream received to downstream node. I try to implement it by following config in my nginx.conf :

  exec_push ffmpeg -i rtmp://localhost/src/test -vcodec copy -strict -2 -ar 44100 -ac 1 -f flv rtmp://<downstreaming a="a">/src/test -f flv rtmp://<downstreaming b="b">/src/test
</downstreaming></downstreaming>

  it works when everything runs well, but if the downstream node is down, this command will exit and none of the downstream nodes could receive the live stream.

  How could I force ffmpeg to ignore the connetion refused, or is there any better alternative to my implementation ?

• Matplotlib can not save animation

  1er avril 2020, par Justin Furuness

  I have a matplotlib animation and it will not save. If I do not save it, it runs totally fine and without error. When I try to save it errors with a message that is not helpful. I have googled this error and checked everything, but I cannot seem to find an answer to this problem. I have installed ffmpeg. Am I doing something wrong that is obvious ? I am running on ubuntu 19.10 with matplotlib 3.2.1 if that matters.

  



  The code to save the animation is below :

  



      def run_animation(self, total_rounds):
        anim = animation.FuncAnimation(self.fig, self.animate,
                                       init_func=self.init,
                                       frames=total_rounds * 100,
                                       interval=40,
                                       blit=True)
#        Writer = animation.writers['ffmpeg']
#        writer = Writer(fps=15, metadata=dict(artist='Me'), bitrate=1800)
        anim.save('animation.mp4')


  



  The error traceback :

  



  2020-04-01 02:20:58,279-INFO: MovieWriter._run: running command: ffmpeg -f rawvideo -vcodec rawvideo -s 1200x500 -pix_fmt rgba -r 25.0 -loglevel error -i pipe: -vcodec h264 -pix_fmt yuv420p -y animation.mp4
