Jetson Nano FAQ

Q: Is hardware acceleration enabled in ffmpeg?

Or please consider use jetson_multimedia_api. For hooking with ffmpeg, copying decoded YUVs to CPU buffer is done in the frameworks. In jetson_multiemdia_api, you can have frame data in hardware DMA buffers and use hardware engines, without additional memory copy.
