>> Hi, I set the log level to debug and found that all errors are as follow
code:

if (h->cabac.bytestream > h->cabac.bytestream_end + 2 )
                av_log(h->avctx, AV_LOG_DEBUG, "bytestream overread %td\n",
h->cabac.bytestream_end - h->cabac.bytestream);
            if (ret < 0 || h->cabac.bytestream > h->cabac.bytestream_end +
4) {
                av_log(h->avctx, AV_LOG_ERROR,
                       "error while decoding MB %d %d, bytestream (%td)\n",
                       h->mb_x, h->mb_y,
                       h->cabac.bytestream_end - h->cabac.bytestream);
                er_add_slice(h, h->resync_mb_x, h->resync_mb_y, h->mb_x,
                                h->mb_y, ER_MB_ERROR);
                return -1;
            }

[h264 @ 004bf7c0] bytestream overread -26=   98KB sq=    0B f=50/154
