<p>Hello! I'm trying to do something which I'm not sure it is supported. I'm writing a plugin in which I call gst_buffer_add_video_region_of_interest_meta in a loop, adding (presumably) more than one GstVideoRegionOfInterestMeta to a single buffer.<o:p></o:p></p>
<p>In another plugin that consumes the output of the previous plugin, I call gst_buffer_iterate_meta in a loop to try to retrieve the information. But I can only retrieve the first metadata successfully. After the first one, gst_buffer_iterate_meta returns
NULL.<o:p></o:p></p>
<p>So, my question is: is it possible to have multiple GstVideoRegionOfInterestMeta metadata in the same GstBuffer?<o:p></o:p></p>
<p>Thanks!<o:p></o:p></p>
