• Nginx rtmp configurations

  10 février 2015, par Mattia Malonni

  I have this problem

  My /opt/nginx/conf/nginx.conf is like this

  rtmp {
  
      server {
  
          listen 8080;
  
          chunk_size 4096;
  
  
  
          application in {
  
              live on;
  
              exec ffmpeg -i http://bstream.dyndns.org:8000/live/XXXXX/YYYYY/$name.ts -bufsize 100M -acodec aac -strict experimental -vcodec libx264 -g 30 -s 854x480 -vprofile baseline -f flv "rtmp://localhost:8080/live/%{name}";
  
          }
  
  
  
          application live {
  
              live on;
  
          }
  
  
  
      }
  
  }

  And the JWplayer is this :

  <center><div>Loading the player</div></center>
  
  <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&gt;<br />
  
    jwplayer(&quot;player&quot;).setup({<br />
  
      flashplayer: &quot;/flash/jwplayer.flash.swf&quot;,<br />
  
      file: &quot;rtmp://MYIP:8080/live/191&quot;<br />
  
    });<br />
  
  &lt;/script&gt;
  
  

  Cant understand why not working

  If i go to my stat page, i see something like this

  If i leave the player loading and try to execute the command (via terminal)

  ffmpeg -i http://bstream.dyndns.org:8000/live/XXXXX/YYYYY/191.ts -bufsize 100M -acodec aac -strict experimental -vcodec libx264 -g 30 -s 854x480 -vprofile baseline -f flv "rtmp://localhost:8080/live/191"

  Everything is OK

• Multimedia Exploration Journal : The Past Doesn’t Die

  12 juillet 2011, par Multimedia Mike — Game Hacking

  New haul of games, new (old) multimedia formats.

  Lords of Midnight
  Check out the box copy scan for Lords of Midnight in MobyGames. In particular, I’d like to call your attention to this little blurb :

  
  
  

  Ahem, "Journey through an immense world — the equivalent of 8 CD-ROMs." Yet, when I procured the game, it only came on a single CD-ROM. It’s definitely a CD-ROM (says so on the disc) and, coming from 1995, certainly predates the earliest DVD-ROMs (which can easily store 8 CD-ROMs on a disc). Thus, I wanted to jump in a see if they were using some phenomenal compression in order to squeeze so much info into 600 or so megabytes.

  I was surprised to see the contents of the disc clocking in at just under 40 megabytes. An intro movie and an outro movie account for 75% of that. Format ? None other than that curious ASCII anomaly, ARMovie/RPL with Escape 122 codec data.

  Cyclemania

  
  
  

  Cyclemania is one of those FMV backdrop action games, but with a motorcycle theme. I had a good feeling I would find some odd multimedia artifacts here and the game didn’t disappoint. The videos are apparently handled using 3-4 discrete files per animation. I’ve documented my cursory guesses and linked some samples at the new MultimediaWiki page.

  Interplay ACMP
  This is unrelated to this particular acquistion, but I was contacted today about audio files harvested from the 1993 DOS game Star Trek : Judgment Rites. The files begin with the ASCII signature "Interplay ACMP Data". This reminds me of Interplay MVE files which begin with the similar string "Interplay MVE File". My theory is that these files use the ACOMP compression format, though I’m still trying to make it fit.

  Wiki and samples are available as usual if you’d like to add your own research.

• Error while saving a matplotlib animation, missing 'dpi' argument

  27 septembre 2020, par aarcas

  I'm trying to save an animation of matplotlib.animation.AnimationFunc and I get an error saying 'dpi' argument missing. Obviously, I have the dpi set so I don't understand where this error comes from.

  



  I'm running python 3.6 and matplotlib 3.0.3, I also just installed ffmpeg from ubuntu official repositories (Ubuntu 18.04).

  



  This is the part of my code that should affect that, although I think it should be something of the system :

  



  Writer = writers['ffmpeg']
writer = Writer(fps=15, metadata=dict(artist='Me'), bitrate=1800,)
ani = FuncAnimation(fig, anime, interval=time_step *
                    10**3, frames=F, repeat=False,) 
ani.save('standard_map.mp4', writer=Writer, dpi=100)


  



  The errors is :

  



  with writer.saving(self._fig, filename, dpi):
File "/usr/lib/python3.6/contextlib.py", line 159, in helper
    return _GeneratorContextManager(func, args, kwds)
File "/usr/lib/python3.6/contextlib.py", line 60, in __init__
    self.gen = func(*args, **kwds) TypeError: saving() missing 1 required positional argument: 'dpi'


  



  I tried both adding the lines they suggested there and the error stills the same.

  



  plt.rcParams['animation.ffmpeg_path'] = '/usr/bin/ffmpeg'


  



  I also tried changing the writer to 'imagemagick' the one set on Ubuntu by default and the error persists.
