Hi,
I am using encoder on jetson with nvidia-jetpack:

Package: nvidia-jetpack

We wrote an encoder based on this sample:
usr/src/jetson_multimedia_api/samples/01_video_encode

I would like to know what I should do in order to resize it on the fly?

Hi,
For changing resolution, you would need to destroy encoder and re-initialize it with new resolution. Resolution cannot be changed on the fly.

Bitrate, framerate, force-IDR can be changed on the fly.
