dusty-nv / jetson-utils

Hello,

This is not as much an issue as it is a question. I was wondering how come there is no (need to) call cudaDeviceSynchronize() at the end of the following function:

jetson-utils/codec/gstBufferManager.cpp

Line 299 in e6ea755

    
           int gstBufferManager::Dequeue( void** output, imageFormat format, uint64_t timeout )

There are some color conversions going on that are never synced as far as I can tell. I also noticed that in the gstEncoder::Render(), which has a very similar implementation, there is a call to synchronize:

jetson-utils/codec/gstEncoder.cpp

Line 716 in e6ea755

CUDA(cudaDeviceSynchronize()); // TODO replace with cudaStream?

Thanks!

Missing `cudaDeviceSynchronize()` in `gstBufferManager::Deque()`
