Auxiliary Streams

A pipeline demonstrating the use of Auxiliary Streams in Savant. The pipeline contains element, Multiple Resolutions. It scales the frame to multiple resolution and sends the frames to the auxiliary streams.

Tested on platforms:

  • Nvidia Turing, Ampere
  • Nvidia Jetson Orin family

Prerequisites

git clone https://github.com/insight-platform/Savant.git
cd Savant
git lfs pull
./utils/check-environment-compatible

Note: Ubuntu 22.04 runtime configuration guide helps to configure the runtime to run Savant pipelines.

Run Demo

# you are expected to be in Savant/ directory

# if x86
docker compose -f samples/auxiliary_streams/docker-compose.x86.yml up

# if Jetson
docker compose -f samples/auxiliary_streams/docker-compose.l4t.yml up

# open 'rtsp://127.0.0.1:554/stream/video-360p', 'rtsp://127.0.0.1:554/stream/video-480p',
# 'rtsp://127.0.0.1:554/stream/video-720p' in your player
# or visit 'http://127.0.0.1:888/stream/video-360p', 'http://127.0.0.1:888/stream/video-480p', 
# 'http://127.0.0.1:888/stream/video-720p' (LL-HLS)

# All the streams on AO-sink are 1280x720 for simplicity of deployment.
# You can see the different quality of the streams since AO-sink upscales them to 1280x720.

# Ctrl+C to stop running the compose bundle

Note: If you meet an issue with encoder (e.g. RuntimeError: Received error "gst-core-error-quark: ENCODER INITIALIZATION FAILED (1)" from nvv4l2h264enc2.), you can try to decrease auxiliary streams, comment one of the sections in the demo.yml, e.g.:

        resolutions:
          # suffix for source ID of the auxiliary stream
          - suffix: '-360p'
            width: 640
            height: 360
          #- suffix: '-480p'
          #  width: 856
          #  height: 480
          - suffix: '-720p'
            width: 1280
            height: 720
