    28 novembre 2014, par hitesh

    I am trying to configure ffmpeg using this tutorial - http://myownhomeserver.com/2012/12/how-to-install-ffmpeg-php-php-5-4-on-windows-8-xampp-1-8-1/ but after I had done initial configuration, it is throwing error.

    I copied php_ffmpeg.dll in ext folder also added it in php.ini file extension=php_ffmpeg.dll copied other files to system32 folder. but it is throwing error while restarting apache. it is throwing below errow

    ---------------------------
    httpd.exe - System Error
    ---------------------------
    The program can't start because avcodec-52.dll is missing from your computer. Try reinstalling the program to fix this problem. 
    ---------------------------
    OK   
    ---------------------------
    

    I can see that above tutorial was for PHP 5.4 and above so I found this tutorial http://myownhomeserver.com/2012/02/how-to-install-ffmpeg-php-for-windows-apache-http-server/

    this is for PHP 5.3 but still it seems to show same error for me

  • how to reduce output size while capturing webcam video using ffmpeg ?

    27 novembre 2014, par Chris Snow

    I am capturing output from my webcam as follows:

    ffmpeg -y -an -vcodec rawvideo -f video4linux2 -s 320x240 -i /dev/video0 out.mpg
    

    I would like to trade off quality of the output in order to reduce the amount of data that is recorded but I don't know what options to set.

    Any pointers will be appreciated - video encoding is a completely new area and unknown area of computer science for me.
