after decoding, you can know the resolution change. you can add a src probe on nvurisrcbin, please refer to this [FAQ](https://forums.developer.nvidia.com/t/deepstream-sdk-faq/80236/17) for how to get width and height.

after decoding the encoded data, the decoder will know the new with and height. please refer to the comment above.
