Zero-Copy RTSP Video Ingestion with Python PyAV & PyTorch
Directly demux H.264/H.265 RTSP NAL units into GPU memory tensors without OpenCV CPU copy overhead.
Need a live RTSP stream link right now to test this setup in VLC or OpenCV?
#1Ingesting RTSP with PyAV
PyAV provides direct C-level bindings to FFmpeg libavformat and libavcodec:
import av
container = av.open(
"rtsp://rtsplink.com/live/test?token=demo",
options={"rtsp_transport": "tcp", "fflags": "nobuffer"}
)
for frame in container.decode(video=0):
img = frame.to_ndarray(format="bgr24")
print(f"Decoded frame size: {img.shape}, PTS: {frame.pts}")
