 Sorry miss that transcode use a pool of video buffer.

 It is fine because what it does is a pool of buffers.
 This pool will contain unused pictures and they should naturally have a
refcount of 0. Overriding the value to 0 (and maybe the picture status)
will do the trick as you override the destructor.
