GO-LIVEPEER TESTNET

• Impersonate the livepeer user:

su - livepeer

• Export the library path:

export LD_LIBRARY_PATH=/usr/local/lib/

• Change into the go-livepeer directory:

cd "$HOME/go-livepeer"

• Start a screen session for the broadcaster:

screen

Hit <ENTER> a few times to get to a command prompt.

• Start an offline orchestrator/transcoder on port 8935:

./livepeer -orchestrator -transcoder -network offchain -serviceAddr 127.0.0.1:8935 -orchAddr 0.0.0.0:8935 -nvidia 0

NOTE: Use the -nvidia argument to control the GPUs being used. To use the first two GPUs, specify, -nvidia 0,1

• Once the orchestrator/transcoder is running, hold <CTRL> and type <A> then <D> to leave the screen session running in the background.

• Start another screen session for the broadcaster:

screen

Hit <ENTER> a few times to get to a command prompt.

• Start an offline broadcaster on port 8936, connected to the orchestrator on port 8935. A secret is not necessary here because the secret is a Orchestrator / Transcoder concept):

./livepeer -broadcaster -orchAddr 127.0.0.1:8935 -cliAddr 127.0.0.1:7936  -httpAddr 127.0.0.1:8936

• Once the broadcaster is running, hold <CTRL> and type <A> then <D> to leave the screen session running in the background.

--

• At this point, you can log out if you like, or you can also log in with multiple windows if you wish to monitor both processes.

• You can list the screen sessions with the command:

screen -x

• To access the screen session, specify the session ID as an arg:

screen -x xxxx

You can always leave the screen session running in the background by holding <CTRL> and then typing <A> followed by <D>.

• stream into port 1935 using ffmpeg

ffmpeg -re -stream_loop -1 -i SomeVideo.mp4 -c:a copy -c:v copy -f flv rtmp://localhost:1935/movie

• playback from port 8936 using ffplay

ffplay http://localhost:8936/stream/movie.m3u8
