Setup VideoCoin Worker in VideoCoin Network Console
Use the "Worker" tab in VideoCoin Network Console and create the worker. The "Client Id" assigned to the worker needs to be used while running the worker as described in the following section. 
Start the worker
Set the environment variables and start the transcode worker as shown below.
SECRET=xxxxx
CLIENT_ID=XXXXXX-9984-465f-9b6a-683639ed0fa6

./transcoder_arm mine -k <keyfile>
Environment variables and command-line options
-k keyfile
Ethereum key file.
Ethereum key file can be created using the ethkey tool as detailed in the following link..
https://github.com/ethereum/guide/blob/master/ethkey.md 
CLIENT_ID
Worker ID obtained from the worker menu of VideoCoin Network Console
SECRET
Password for the ethereum key file
DISPATCHER_ADDR
Obtain the dispatch address from VideCoin support
Example: d.dev.videocoin.network:5008
Performance:
Raspberry Pi supports encoding up to 1080p @30fps. Transcoding live streams at 1080p resolution and 30fps may introduce some discontinuities as there is not much head room to support jitter in the live stream. It is recommended to use only for VOD applications when transcoding at 1080p,30fps.
