• Does FFMPEG utilize CUDA or any other hardware acceleration yet ?

  25 janvier 2012, par Jason

  Simple question, but I am having trouble finding the answer.

  We are deciding on a transcoding engine (preferrably open source) and it looks to me that FFMPEG does not utilize hardware acceleration, but I am not sure.

  I believe ffmpeg uses libavcodec, the same library used in countless other products, such as Handbrake. I can't believe they don't support hardware acceleration, therefore, my question.

• Listing files in numerical order instead of alphabetical ?

  24 janvier 2012, par lazeR

  Basically, I have a bunch of files with a common prefix (logo%d.jpg) .

  When they are viewed using ls or even when looping through a directory in PHP, I don't receive them in numerical order, meaning logo1.jpg, logo2.jpg.

  Instead I get them in alphabetical order, like:

  logo1.jpg, logo10.jpg, logo11.jpg ... logo 19.jpg, logo2.jpg (Instead of logo20.jpg)

  Is there a way to ouput them in numerical order? logo1, logo2, logo3 .. etc.

• How to install ffmpeg and lame on Xampp for Mac ?

  24 janvier 2012, par Guido Lemmens 2

  I've searched the internet for days to find out how to install ffmpeg (and lame) on XAMPP for Mac (PHP). But I didn't find the key to my quetsion.

  I need to covert mp3's on my webserver (php) using lame, but I like to test it on my XAMPP for Mac first. I think I need the "php_ffmpeg.dll" which can be downloaded at Sourceforge. I found a step-by-step description here but this question only refers to XAMPP for Windows. But I need it for Mac.

  Can anyone help to supply a step-by-step description?

• is there a good library out there that will split a mp3 with php

  24 janvier 2012, par Tamer

  So i have an application takes a uploaded song and allows the user to purchase it. I would like to also create a 30 second clip that the user can preview, but rather then having the user upload two files I want the application to create the 30 second mp3 file based on the original mp3. I found this library which i am using like this

      $oSplit=new CMP3Split(DIR_DOWNLOAD ."Made_To_Love.mp3",243,DIR_DOWNLOAD ."clips/{$rndString}.mp3",30,0);
  

  but it seems to not always produce a 30 second clip

  and i also found this question which is using ffmpeg which i dont know how to use in a php setting.

  Any ideas or suggestions
