Airplay server

This airplay server is a containerized version of the tcp-forwarder example from the java-airplay-server-examples repo.

Container setup

The following commands use the podman container tool. If using docker, you may need to modify the Containerfiles.

Build

NOTE: Before building image, you may wish to change the name of the airplay server by changing QuackPlay to something else in the Containerfile line that uses the sed command.

The multistage Containerfile is recommended due to its smaller size. Build the image with

podman build -t airserver:1.0 . -f Containerfile.multi

Run

To run container, use

podman run --rm --network host --name airserver -d airserver:1.0

To stop container, use

podman stop airserver

Connect to TCP stream

After starting the container, connect to the TCP stream by using either of the following commands.

# Run this (seems to be faster than ffplay)
gst-launch-1.0 -v tcpclientsrc port=5002 ! h264parse ! avdec_h264 ! autovideosink

# or this
ffplay -f h264 -codec:v h264 -i tcp://localhost:5002 -v debug

Recently, on my Manjaro box, the first command has not been working due to the error WARNING: erroneous pipeline: no element "avdec_h264". Instead, I use the modified command

gst-launch-1.0 -v tcpclientsrc port=5002 ! h264parse ! vah264dec ! autovideosink

Bugs

• Cannot reconnect to stream after disconnecting (upstream bug).
