• Cannot save animation in matplotlib : Windows permission denied

  13 mai 2015, par Vladimir

  I’ve been trying for a day long to sort this out, checking similar threads but with no success.
  Stretch’s Cannot save matplotlib animation with ffmpeg helped with previous errors (I had ffmpeg path wrong), but I kept getting Access denied after fixing it.

  My ffmpeg binary is on C:\ffmpeg\bin

  A nice alternative would be to able to export gif files, but I keep getting an ascii error with imagemagick. I think both problems are related, so I wanted to sort out the ffmpeg first.

  I think the problem might have to do with the fact I’m working with Canopy (in Windows 8 64bit), which pretty much hegemonized my path variable and broke some things along the way (e.g. I can’t open IDLE since I installed Canopy, didn’t tried to fix that yet). As I fixed things along the way I found at least 3 distinct path variables, all of which I updated : windows advanced settings path (set manually), windows console path (set via console with setx), and sys.path (set or checked at runtime), adding ";C:\ffmpeg\bin", where ffmpeg effectively is. Regardless I sort out the problem or not, I would like to learn which of these environment variables are relevant for what, I find it very confusing.

  The code is the following :

  # -*- coding: utf-8 -*-
  
  import sys
  
  import numpy as np
  
  from matplotlib import pyplot as plt
  
  from matplotlib import animation
  
  plt.rcParams['animation.ffmpeg_path'] = r'C:\ffmpeg\bin'
  
  if r'C:\ffmpeg\bin' not in sys.path: sys.path.append(r'C:\ffmpeg\bin')
  
  
  
  fig = plt.figure()
  
  ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
  
  line, = ax.plot([], [], lw=2)
  
  
  
  def init():

      x = np.linspace(0, 2, 1000)
  
      y = np.sin(2 * np.pi * (x - 0.01 * i))
  
      line.set_data(x, y)
  
      return line,
  
  
  
  anim = animation.FuncAnimation(fig, animate, init_func=init, frames=200, interval=20, blit=True)
  
  plt.show()

  UPDATE : I followed the steps in this post for granting access to both C :\ffmpeg and destination folder, but no luck :(

• Is there a media server which just receives any rtsp streams and serves them ?

  7 mai 2015, par Given92

  I have some rtmp streams served over nginx-rtmp-module and the number of them will be changed dynamically.

  But for the limit of client, I have to serve them in rtsp protocol. Obviously, It’s not supported by nginx-rtmp-module. So I plan to run a rtsp server in the same device, and convert the rtmp stream into rtsp stream with ffmpeg, then send the rtsp stream to the rtsp server. So that client could play the stream from the rtsp server.

  The trouble is that I could not found a stable server which just receive any rtsp streams and serve them.

  There is an example that fits all my need but it’s a little unstable.

  I run it in verbose mode and send stream with :

  ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>
  
  </name></name>

  and play the stream with :

  gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>
  
  </name></server>

  The video does not appear and there are some repeated warnning like this :

  WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.
  
  Additional debug info:

  When I try :

  gst-launch-1.0 playbin uri=rtsp://<server>/<name>
  
  </name></server>

  it is stuck and no video appear :
