[gst-devel] Question on how to use GstBuffer?

[Clark, Rob]

yes, there are a handful of examples of this..  look for example, in v4l2bufferpool..  xvimagesink, etc..

basically the principle is to subclass GstBuffer, provide your own finalize function that revives the buffer and returns it to your pool of buffers.


(random thought:  really, it's a pattern seen in enough gst elements, that perhaps it would be nice to see a generic GstBufferPool class..)

Hi All,

In my current element, I will create and new a GstBuffer (which means to use g_malloc to allocate buffer) in the _chain() function for each frame.

My question is: Can I allocate several buffers (ring buffers) ahead of time, then I can re-use them and don’t need to allocate buffer for each call of _chain, if yes, how?

Thanks in advanced.
