How to transfer results.json to coco-style

[lpwMei]

Thanks for your working.
I test it on dataset and get a "results.json".But the competition needs different json style just Like
{
"video_id" : int,
"category_id" : int,
"segmentations" : [RLE or [polygon] or None],
"score" : float,
}
How can I convet it?Thanks a lot.
