Fluendo decoder and OpenGl rendering

[leo]

Hi,

I'm trying to use gstreamer and a fluendo decoder (fluvadec) to play a video in an opengl texture.
How can I link the source pad of fluvadec and diplay the video in a texture without using the CPU?

Currently, I'm using gst-plugins-gl and this is my pipeline (video .mov):

filesrc -> qtdemux -> fluvadec -> glupload -> gleffects -> fakesink

I link the gleffects element with my openGl context but i loose the Hardware decoding speed with the link fluvadec->glupload. I'm a beginner with gstreamer, so any help or any idea will be useful  (and sorry for my bad english).

Thanks!

Hi Leo,

fluvadec is pushing out buffers of a specific type that the usual GStreamer elements won't understand.

There are 3 ways to render them :

1) Use fluvasink to render them in an XWindow

2) Use fluvaclutsink to render them in a Clutter Texture 

3) Obtain the Fluendo VA SDK which will provide you with a library, headers and a template sink element to handle those buffers and render them in your OpenGL application by calling the proper API for OpenGL bridging (VAAPI, XVBA, VDPAU).

Best regards,
