"nvvidconv" change parameter on the fly.

Hi there,

We are trying to use “nvvidconv” to rotate and scale video stream. The big thing here is we do not want to set the stream pipeline to pause and back to play on when change those parameters of “nvvidconv”. Do anyone know how to make this work, Thanks


when I talked about the parameters, it mean the resolution. I wanna “nvidconv” can dynamically change the resolution which it scale up to. Thank you.

Hi usaarizona,
Since the buffer is allocated in initialization, it cannot be configured dynamically.

Do you need the resolution to by changed all the time, or it can be fixed three or four cases?
If it is fixed cases, you can try MM APIs and initialized multiple NvVideoConverters.
If it is changed dynamically, you may need to implement it via CUDA.
