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
ion-load-tool -clients <num clients>
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.
Pass -consume
By default load test is only producing streams, use this flag to also subscribe to all remote streams and consume them
Pass -ion-url
Pass -room-name
In case of testing only with one room, client will connect to room with provided name. In case of multi-room test, this name will be used as name prefix (followed by room number)
Pass -seconds
Number of seconds to run test (default is 60)
Pass -audio
By default audio is not sent from the stream
Pass -token
If ION requires authentication with JWT, pass secret key here used to authenticate
Pass -report
Filename for report output. If ommited, report will be printed in stdout
Pass -rooms
NUmber of rooms to create. Each room will have number of clients provided in -clients
Each client subscribes to all published streams in the provided room. A basic consumer with simple out-of-order detection is implemented.
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.
Run separate instances of the load tool.
-produce <file> -clients 1
-consume -clients N
-consume -produce ./big-buck-bunny_trailer.webm -token <secret_key> -rooms 4 -clients 4 -report ./report.json
