• ffmpeg convert any file to any file

  28 mai 2015, par Vishnu

  I Want simple command to convert any supported file to any file with little possible video compression.

  for example

  avi to mp4
  
  mp4 to 3gp
  
  .
  
  .etc..

  I tried below code

  ffmpeg -i infile.flv outfile.3gp

  It works for some but for some other like flv to 3gp conversion it throws error like below and also output file size is very large than input.

  "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height" 

  P:s i compiled with below librareis

  ./configure --enable-version3 --enable-libopencore-amrnb --enable-libvo-aacenc --enable-libopencore-amrwb --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-gpl --enable-postproc --enable-nonfree

• playing live streaming with video.js

  12 juin 2015, par randomuser1

  I want to stream on a webpage a video live that I receive from a server (with ffserver). So far when I write a very simple code :

      <code class="echappe-js">&lt;script src=&quot;http://www.andy-howard.com/js/libs/jquery-1.8.2.min.js&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;http://vjs.zencdn.net/4.12.6/video.js&quot;&gt;&lt;/script&gt;
     
  
  

  then it doesn’t work. But when I replace the line :

  <source src="http://10.172.180.235:8090/live.flv" type="video/x-flv">
  
  </source>

  with this one :

  <source src="http://vjs.zencdn.net/v/oceans.mp4" type="video/mp4">
  
  </source>

  then I can see the stream, but it comes from a file... Is there a way to display on my webpage live stream coming from ffserver ? Thanks.

• FFMPEG pushed RTMP stream not working on Android & iPhone

  1er décembre 2015, par BlackDivine

  I have to make a semi-live-stream. I used Nginx-rtmp module and then pushed content to it via ffmpeg using :

  ffmpeg -re -i content.mp4 -r 25 -f fvl "rtmp://rtmp.server.here"

  The stream runs fine when I open it in VLC from "rtmp ://rtmp.server.here"

  But I also have to make iPhone and Android apps that play these streams. And that’s the problem, the stream doesn’t work on Android and iPhone.

  If I use Wowza streaming cloud and stream to Wowza cloud instead of my own nginx-rtmp server then the same app written for Android & iPhone can playback the stream just fine.

  Now either nginx-rtmp is not working right, or what else ? I’ve also tried crtmpserver and the same thing happens.

  What I want to acheive :
  I have to develop a system where we can upstream a TV-Channel (have rights for it) to a server and then make a website, android app & iPhone app so consumers can watch the live channel.

  The uploading part I have a clue of, probably a TV tuner card and Open Broadcast Software to stream it to server. But the Live playback is new to me.

  UPDATE : I also used ffprobe and here’s the output. (See the last line)

  Update 2 :
  I got my stream working by using Licensed copy of Wowza streaming server. Everything works now. But obviously this will not be an option for everyone that’s why I am not posting it as an answer.
