Hi all, I'm using libavformat / libavcodec to extract motion vectors from files encoded by different codecs (MPEG-2, H.264,...).
Do I understand correctly that if motion vectors exist for macro-block or can be predicted, they are available in the motion_val field? What happens when a macro-block contains several links to other blocks (the case of a B-frame; ability for weighted mixtures in H.264)? Is any kind of motion vector (say, to past reference frames for B-type blocks) inserted in the motion_val at all for such blocks? If I'm misunderstanding something, please correct me. I've just started to dig in the topic. Thanks, -- Vadim Kantorov +33 (603) 292-769
