Requesting the GLTextureUpload meta on buffers in the bufferpool prevents such metas from being de-allocated when buffers are released in the sink. This is particulary useful in terms of performance when using the GLTextureUploadMeta API since the GstVaapiTexture associated with the target texture is stored in the meta. https://bugzilla.gnome.org/show_bug.cgi?id=712558 Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
