A METHOD AND A DEVICE FOR MANAGING ENCODED IMAGE FRAMES IN A DATA BUFFER

A device and a method for managing encoded image frames in a data buffer. The method comprises: obtaining 302 encoded image frames arranged in GOPs, each GOP comprising: a single intra-frame, and two or more frame subgroups. Each subgroup comprises a single directly encoded inter-frame, and zero or more indirectly encoded inter-frames. The method comprises determining 304 whether a buffer fullness requirement is fulfilled. When fulfilled, the method comprises: selecting 306 one or more frames to be removed from the data buffer and removing 308 the selected one or more frames. The selected one or more frames is at least one out of: a non-referenced encoded image frame and a frame subgroup out of the two or more frame subgroups. The method also comprises: storing 310 one or more obtained encoded image frames.
