• FFmpeg Lame output buffer too small, fix in Windows ?

  4 juillet 2012, par Tyler

  All the search results for this seem to return Linux command line solutions.

  The bug means that although a video is successfully converted, an error message

  "lame : output buffer too small (buffer index : 10398, free bytes : 394)
  Audio encoding failed (avcodec_encode_audo2)"

  is returned to the software that I am using with it. Apparently, downgrading the version of lame to 3.97 will solve this problem. But again, I have only found fixes for this in Linux.

  Edit : I get the above error message when I try to convert a given Mpeg file to flv using the following (or similar) command :

  "-i " + sourceVideoPath + " -sameq -ar 22050 " + outputVideoPath;

  The error message is same whether run from my program or direct from the command line.

  I have also tried to download the latest static version of FFmpeg from here but the error message remains.

  Could anyone direct me on how to downgrade the lame version in windows, or point me to a download without the bug, or tell me of any other way to solve this ?

• Install FFMPEG on WAMP

  1er décembre 2014, par nico55555

  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 ?

• nginx video mp4 streaming - jwplayer seeking

  18 juin 2012, par abrahab

  As you can see nginx streaming solution works and return different content-length when flv requested with start parameter :
  http://www.hotgirlscompany.com/1.flv?start=0
  http://www.hotgirlscompany.com/1.flv?start=300000

  But the problem that jwplayer v5 can not seek this video to any position. Seems (from http sniffer) player request ?start=0 and then ignore any mouse clicks at loading line, and can not go to position I want).

  Of course, I added provider=http to flashVars.
  You can download the video and see that its converted as H.264/AAC. Then maked mp4box -inter 500 1.flv. But still can not steam it :(

  Any suggestions ?
  Maybe example how to property reconvert this video with ffmpeg to make it playable ?
