re: PHP Video Uploading

Sounds like you don't have the ffmpeg dll installed.

Have you?

re: PHP Video Uploading

The error really says it all, doesn't it.

You can not use this function on multithreaded Web servers, which pretty much all modern servers are.

You will instead have to load the DLL as an extension in your php.ini configuration file.

Hello Atli,

I checked the php.ini file and there is an extension called: extension=php_ffmpeg.dll

If I need a different extension, which one is it and where can I get it from.

Thanks.

re: PHP Video Uploading

This actually doesn't make sense...

You are trying to load this extension into PHP, and then you try to execute "ffmpeg" via a shell command.

What are you trying to do here?
Load a PHP extension to do this or use a external application?

This ffmepg extension you are trying to use doesn't seem to be an official PHP extension so I can't really say how it is supposed to work. You will have to find out how to use it from wherever you got it.

But, like I said in you other thread, if you plan on using a shell command, the application you are trying to execute has be be installed and working properly outside PHP first.
A good way to test this to try to command in your OS's CLI first to see if it works.
