• MPD doesnt load ffmpeg as decoder

  10 août 2022, par dmSherazi

  I am using openwrt 21.2.3 and mpd on it. I have compile mpd full and libffmpeg full as well as ffmpeg-full packages.
But my mpd wont load ffmpeg as decoder. Also tried to force it by adding decoder { plugin “ffmpeg” enabled “no” }” line to /etc/mpd.conf

  


  below is my mpd.conf

  


  log_file "syslog"

bind_to_address "127.0.0.1"
bind_to_address "192.168.1.16"

input {
    plugin          "curl"
}

audio_output {
    type            "alsa"
    name            "sun4icodec"
    device          "plug:dmix"
    mixer_control   "Power Amplifier"
}

decoder {
     plugin  "ffmpeg"
     enabled  "yes"
}


  


  the mpd —version output is as follows

• FFMPEG, DrawText Issue in Live Stream

  7 décembre 2022, par Kenneth

  I am using the following command to create an H264 stream with text data from a text file. Example data is fake. I am sending this to an RTSP server that then allows clients to connect. I am connecting from VLC to view the stream.

  


  See update, this only happens for the live stream. If I output to file, it looks correct.

  


  OS : Windows 10

  


  ffmpeg -f lavfi -re -i color=size=1280x720:rate=1:color=black ^
  -vf drawtext="fontsize=16:fontfile=C\\:/Windows/fonts/consola.ttf:fontcolor=white:textfile='livetext.txt':x=50:y=50: reload=1" ^
  -c:v libx264 -preset ultrafast -tune zerolatency -x264-params keyint=10:min-keyint=10 ^
  -f rtsp rtsp://127.0.0.1:60000/sorting


  


  The issue I am having is that the text shown in the video seems to be limited to 10 rows. On a fresh restart, I get even less. I don't see anything mentioned in the documentation about a limitation on length.

  


  I have tried different -preset and -tune options. Nothing improves this issue.

  


  Are there settings I should adjust to help this ?

  


  

  


  Console Output :

  


  ..\ffmpeg\ffmpeg -f lavfi -re -i color=size=1280x720:rate=5:color=black -vf drawtext="fontsize=20:fontfile=C\\:/Windows/fonts/consola.ttf:fontcolor=white:textfile='livetext.txt':x=50:y=50: reload=5"  -c:v libx264 -preset ultrafast -tune zerolatency -x264-params keyint=10:min-keyint=10  -f rtsp rtsp://127.0.0.1:60000/sorting

  Update 1 :

  


  If I output to a file, the text is shown correctly (shown below). If I take out the -re argument for the output to match input rate, I get 150fps, so processing power does not seem to be the issue.

  


  

  


• Progress with rtc.io

  12 août 2014, par silvia

  At the end of July, I gave a presentation about WebRTC and rtc.io at the WDCNZ Web Dev Conference in beautiful Wellington, NZ.

  

  Putting that talk together reminded me about how far we have come in the last year both with the progress of WebRTC, its standards and browser implementations, as well as with our own small team at NICTA and our rtc.io WebRTC toolbox.

  

  One of the most exciting opportunities is still under-exploited : the data channel. When I talked about the above slide and pointed out Bananabread, PeerCDN, Copay, PubNub and also later WebTorrent, that’s where I really started to get Web Developers excited about WebRTC. They can totally see the shift in paradigm to peer-to-peer applications away from the Server-based architecture of the current Web.

  Many were also excited to learn more about rtc.io, our own npm nodules based approach to a JavaScript API for WebRTC.

  

  We believe that the World of JavaScript has reached a critical stage where we can no longer code by copy-and-paste of JavaScript snippets from all over the Web universe. We need a more structured module reuse approach to JavaScript. Node with JavaScript on the back end really only motivated this development. However, we’ve needed it for a long time on the front end, too. One big library (jquery anyone ?) that does everything that anyone could ever need on the front-end isn’t going to work any longer with the amount of functionality that we now expect Web applications to support. Just look at the insane growth of npm compared to other module collections :

  

  For those that – like myself – found it difficult to understand how to tap into the sheer power of npm modules as a font end developer, simply use browserify. npm modules are prepared following the CommonJS module definition spec. Browserify works natively with that and “compiles” all the dependencies of a npm modules into a single bundle.js file that you can use on the front end through a script tag as you would in plain HTML. You can learn more about browserify and module definitions and how to use browserify.

  For those of you not quite ready to dive in with browserify we have prepared prepared the rtc module, which exposes the most commonly used packages of rtc.io through an “RTC” object from a browserified JavaScript file. You can also directly download the JavaScript file from GitHub.

  

  So, I hope you enjoy rtc.io and I hope you enjoy my slides and large collection of interesting links inside the deck, and of course : enjoy WebRTC ! Thanks to Damon, JEeff, Cathy, Pete and Nathan – you’re an awesome team !

  On a side note, I was really excited to meet the author of browserify, James Halliday (@substack) at WDCNZ, whose talk on “building your own tools” seemed to take me back to the times where everything was done on the command-line. I think James is using Node and the Web in a way that would appeal to a Linux Kernel developer. Fascinating !!
