Hello,
The Jetson Nano is a wonderful little board. I have on x64 a Python project where I capture an HDMI stream with ffmpeg, process the video and audio and create a processed RTMP stream with ffmpeg. The capture card gives me MJPEG 1280x720 30 FPS video and 44100Hz float32 audio.
The architecture is like this:
HDMI card → ffmpeg → 2 named pipes for audio and video
Read pipes in Python, process the stream
Output the processed stream to another 2 named output pipes
Create RTMP stream with another ffmpeg process by reading the output pipes
I easily achieve 30 FPS on x64. Can I create a more efficient architecture for Jetson Nano? Can I somehow also use the GPU? I can only achieve 15 FPS on Nano ATM, even if I just pass-through the stream without any processing. The ARM CPU load is about 210%. I also want to perform disk IO during processing, is it just too ambitious for this little board?
Thank you,
Paul
