Can I stream the video with bounding boxes as an RTSP stream to a server? about inference

Hi @rj-indro, inference does not deliver such functionality out of the box, however you could pipe annotated frames to ffmpeg which then can stream them back through RTSP.

import os

import cv2


os.mkfifo(path="/path/to/pipe")
pipe = open(file="/path/to/pipe", mode="wb", buffering=0)

# somewhere in your code, i.e. in custom_sink
# assuming frame was already scaled to known resolution, i.e. 1280x720
annotated_frame_bytes = cv2.cvtColor(annotated_frame, cv2.COLOR_BGR2RGB).tobytes()
pipe.write(annotated_frame_bytes)

Then in another terminal:

# assuming 10 fps at source
ffmpeg -f rawvideo -video-size 1280x720 -r 10 -i /path/to/pipe -f flv rtsp://your_destination

hi @rj-indro, I hope example above was helpful. I will close this issue but please feel free to reopen it if you have more questions.
