• Virtual host compared to multiple servers

  9 septembre 2011, par josiecat

  This may be dumb but has me wondering why and I know how to setup the virtual host but need to know the why or what it is good for.

  Why do you setup virtual host for local development and why not just put sub directories ?

  What are the real world uses and how do you use virtual host ?

  (my normal set up as of now)
  I use Mamp and just put more folders (speaking dummy terms here) in the htdocs folder. Is that ok what am I missing ?

  The reason why I would like to use virtual hosting is because I would like to have a few servers to try different technologies (e.g. adding ffmpeg support for streaming video and many others ) but do I use virtual hosting to be able to have more than one server or do I need to use something like virtual machine to have multiple servers with different versions of PHP, Mysql etc...?

  I understand how to set this stuff up just don't understand the difference from virtual host to multiple servers ? could I actually set up one with php just the basic and another for php with ffmpeg-php and other stuff like zend or what ever just to have different server environments to basically mock the actual server that the project will land when done ?

• Playing RTSP stream in Android

  9 décembre 2014, par Kamil

  I’m trying to play video stream on Android device. Unfortunatelly I still get the same problem with MediaPlayer/VideoView. I’m searching for a few days, but still haven’t found any working solution.
  For test purposes I’m using MediaPlayer app from API Demos (API Demos/Media/MediaPlayer/Play Streaming Video).
  Here is code snippet for playing stream

  mMediaPlayer = new MediaPlayer();
  
  mMediaPlayer.setDataSource(path);
  
  mMediaPlayer.setDisplay(holder);
  
  mMediaPlayer.prepare();
  
  mMediaPlayer.setOnBufferingUpdateListener(this);
  
  mMediaPlayer.setOnCompletionListener(this);
  
  mMediaPlayer.setOnPreparedListener(this);
  
  mMediaPlayer.setOnVideoSizeChangedListener(this);

  When I try to play stream I get this info from logcat
  http://pastebin.com/5Uib5CH5

  This is configuration of ffserver streaming the video

  Port 8090
  
  BindAddress 0.0.0.0
  
  
  
  RTSPPort 7654
  
  RTSPBindAddress 0.0.0.0

  If anyone can advise me how to fix it, or at least indicate an mistake, I will be grateful.

• x264 rate control set

  2 juillet 2015, par chinayin

  I have been learning x264 encode for months. What I need is to control the rate and get an average bitrate. Following is my set, I got an average bitrate but the picture quality is bad, so I need your suggestion or something that can help me learn more about x264.

  Params.rc.i_rc_method = X264_RC_ABR ;
  
  Params.rc.i_bitrate = nBitRate*0.65/1000  ;
  
  Params.rc.i_vbv_buffer_size = nBitRate/1000;
  
  Params.rc.i_vbv_max_bitrate = nBitRate*0.65/1000 ;
  
  Params.rc.f_vbv_buffer_init = 1.0 ;
  
  Params.rc.f_rate_tolerance = 1.0 ;                              
  
  Params.i_fps_num =  ParamIn.dFrameRate*0.6 ;
  
  Params.i_fps_den = 1 ;
  
  Params.i_width = ParamIn.nWidth ;
  
  Params.i_height = ParamIn.nHeight ;
