Hi all, I want to discard some MBs of a B-FRAME from decoding. In fact, I want to avoid some special MBs to be decoded and instead copying MBs of one of its parents. Note that no B-Frame is encoded as a reference frame. The best function for me to discard a list of MB is:
(/libavcodec/h264_slice.c) static int decode_slice(struct AVCodecContext *avctx, void *arg) FRAME_MBAFF(h) is false and the clip entropy is cabac. 1)How can I disable ret = ff_h264_decode_mb_cabac(h, sl); and ff_h264_hl_decode_mb(h, sl) for a macro block where (sl->mb_x==my_x_id && sl->mb_y==my_y_id) with no effect on decoding the rest of MBs in a B-Frame? 2) If not possible, is it possible to call ret = ff_h264_decode_mb_cabac(h, sl); but don't execute ff_h264_hl_decode_mb(h, sl) for some specific MBs (again with not effects on other MBs) Thank you.
