• Open source media server for web service.

  20 février 2016, par Scarface

  I am currently building a website where users can listen to music, and watch videos. However, I am worried about the media content(music/videos) being downloaded from the website(I initially stuck to the HTML5 video/audio tags), I did a little research and found that my best option to prevent this was by using a media server, I have search for free open source media servers to use, but none seem promising. I thought my best bet was ffmpeg, but I am scared to use it as there it seems to be no longer maintained. Does anyone know of any good media servers out there I could use ?

• FFMpeg concat streams

  26 mars 2016, par chourizo

  I am trying to receive two H264 UDP streams from two cameras, and save them to one file (so they are always synchronized). I tried a lot of things, but it always says that there is no video on the second stream (although I can watch it).

  ffmpeg -probesize 20M -analyzeduration 20M -i udp://@127.0.0.1:1234 -probesize 20M -analyzeduration 20M -i udp://@127.0.0.1:1235 -filter_complex "[0:v]fps=15,scale=320:240,setsar=1/1,setpts=PTS-STARTPTS[v0]; [1:v]fps=15,scale=320:240,setsar=1/1,setpts=PTS-STARTPTS[v1]; [v0][v1]concat=n=2:v=1:a=0 [v0] [v1]" -map "[v0]" -map "[v1]" -threads 0 -y kk.ts

  Is it possible to apply the concat to real time streams, so we have a video with two programs as a result ?

• Xuggle build failed on ubuntu x64 ?

  3 avril 2012, par beginner

  After downloading the source code from GIT hub I setup the enviroment variables
  as Xuggle YouTube Video said so

     export XUGGLE_HOME=/usr/local
  
     export PATH=$XUGGLE_HOME/bin:$PATH
  
     export LD_LIBRARY_PATH=$XUGGLE_HOME

  Then I simply started the ant test by command

  ant run-tests

  Which gave me following output with error in the end ..
