• How can I have ffmpeg receive both video and audio over RTP ?

  23 mai 2018, par KallDrexx

  I am trying to instruct FFMPEG to receive h264 video and aac audio via RTP using out of band session initialization.

  To do that I have the following local SDP :

  v=0
  
  o=sb
  
  s=-
  
  t=0 0
  
  c=IN IP4 127.0.0.1
  
  m=video 12100 RTP/AVP 96
  
  a=rtpmap:96 H264/90000
  
  m=audio 12101 RTP/AVP 97
  
  a=rtpmap:97 MPEG4-GENERIC/44100/2

  When I load ffmpeg with :

  ffmpeg -loglevel debug -protocol_whitelist "file,rtp,udp" -i .\test.sdp -strict -2 test.flv

  I get the following error :

  [udp @ 0000022d7fdafe80] bind failed: Error number -10048 occurred
  
  [AVIOContext @ 0000022d7fd84900] Statistics: 154 bytes read, 0 seeks
  
  .\test.sdp: Invalid data found when processing input

  Confused by that error code I loaded it up on a Linux VM and the bind error I got was Address already in use.

  I tried changing both of those port numbers all around and kept getting that error. Finally I removed one of the media streams from the SDP so it ONLY had video or ONLY had audio and no binding error occurred.

  How can I get ffmpeg to bind to multiple RTP ports for RTP ingestion ?

• Install FFMPEG on WAMP

  I've probably spent over 12 hours trying to install FFMPEG on WAMP. I'm aware that other people have had this question answered on this site, however it does not work for my setup.

  



  I have tried the below :

  



  Download ffmpeg_new
Copy php_ffmpeg.dll from the php5 folder to the C:\wamp\bin\php\php5.2.9-2\ext
Copy files from common to the windows/system32 folder
Add extension=php_ffmpeg.dll to php.ini file
Restarted all services (Apache, PHP...)


  



  My current setup is PHP 5.2.1, Apache 2.0.63. I have a Windows 7 64bit computer.

  



  I get the following error in my PHP error log :

  



  [22-Jun-2012 01:39:31] PHP Warning : PHP Startup : Unable to load dynamic library 'c :/wamp/bin/php/php5.2.1/ext/php_ffmpeg.dll' - The specified module could not be found.
 in Unknown on line 0

  



  Obviously I have placed the module in the ext folder.

  



  Phpinfo.php verifies that the FFMPEG module is not being loaded. I have tried installing PHP 5.3 (with a later FFMPEG version), 5.2.6 and 5.2.9-2, but the module still fails to load. Is there anything else I should try ? Does having a 64bit Windows 7 computer make any difference ?
