Ion load testing tool

Test Data

Publishing of files in the following formats are supported.

Container	Video Codecs	Audio
IVF	VP8	none
WEBM	VP8 and VP9	ogg

If your data is not in this format you can transcode with:

ffmpeg -i $INPUT_FILE -g 30 output.(ivf|webm)

See the ffmpeg docs on VP8 or VP9 for encoding options

Run

ion-load-tool -clients <num clients>

Producer

Pass -produce <encoded video>

Each client starts stream playback in an offset position from the last with a different track and SSRC ID to simulate independent content.

Consumers

Pass -consume

Each client subscribes to all published streams in the provided room. A basic consumer with simple out-of-order detection is implemented.

Test Configurations

N to N fully connected

Run both produce and consume on the same command

-produce <file> -consume -clients N

This creates N clients publishing a stream, each of which will subscribe to the other N-1 client streams.

1 to N fanout

Run separate instances of the load tool.

Producer

-produce <file> -clients 1

Consumer

-consume -clients N
