#1Ingesting RTSP with PyAV

PyAV provides direct C-level bindings to FFmpeg libavformat and libavcodec:

PyAV RTSP Demuxer
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}")
    break
