Pushes the given ctx onto the CPU thread's stack of current contexts. The specified context becomes the CPU thread's current context, so all CUDA functions that operate on the current context are affected.

Parameters:

a GstCuda.CudaContext to push current thread

Returns (Number) –

true if ctx was pushed without error.

Since : 1.22

GstCuda.CudaContext.push 

def GstCuda.CudaContext.push (self):
