           Summary: [PATCH] enable our get/release_buffer functions in
                    ffmpegdec
           Product: GStreamer

        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-ffmpeg

This patch enable our get/release_buffer functions in ffmpegdec. There are two
define in the code:
- ENABLE_OUR_GET_BUFFER
  This define enables the patch. 
- FORCE_OUR_GET_BUFFER
  This define forces the usage of our get/release functions even if ffmpeg needs
to align width or height. 

The performance gain is something like 20% (ex. from 25% to 19%) when playing an
"aligned" video, it's ~5% (ex. from 43% to 40%) when width or height needs to be
aligned. 
Right now there is no codec whitelist/blacklist because i don't know how to test
it :) I have only xvid or divx files and they all works fine..
