I have a question and I hope someone can help me.
I want to extract all motion vectors in P_type mocroblock in a P_frame
h264 video with libx264 (x264). libx264 uses X264Context in the function
x264_frame to encode
video. Then, I want to know how can I access to macroblocks in a picture
how to access to motion vectors table on this picture while using the
With MpegEncContext we can access them while using MpegEncContext struct's
mb_type, *mvs, mb_width, mb_height and mb_stride. But I don't know how
to have such informations (
mb_type, *mvs, mb_width, mb_height and mb_stride) with X264Context
Please I need your help.
