Online Video Streaming

DASH Video Streaming

1. Create a Layer 4-7 cross-connect by using the details pictured below.
   
   

   Use the following sample URL link to run DASH video : https://s3.amazonaws.com/_bc_dml/example-content/sintel_dash/sintel_vod.mpd

2. Start the Layer 4-7 cross-connect and select the Video-View tab in the app to view the running video.
   
   

   While the video is running, the Layer 4-7 cross-connect statistics (e.g. Bytes-RD, Total-URLs, URLs/s, Rx Rate, Total-Buffers, Total Wait Time, Mean Video format, Mean Audio format) are able to be viewed in the Layer 4-7 tab.

HLS (HTTP Live Streaming)

1. Create a Layer 4-7 cross-connect by using the details pictured below.
   
   

   Use the following sample URL to run HLS: https://demo.unified-streaming.com/k8s/features/stable/video/tears-of-steel/tears-of-steel.ism/.m3u8

2. Start the Layer 4-7 cross-connect and select the Video-View tab in the app to observe the running video.
   
   

While the video is running, the Layer 4-7 cross-connect statistics (such as Bytes-RD, Total-URLs, URLs/s, Rx Rate, Total-Buffers, Total Wait Time, Mean Video format, Mean Audio format) are able to be in the Layer 4-7 tab.

The same method of creating a Layer 4-7 cross connect and observing the media in the app can be applied to other media types such as Smooth, RTSP, and MP4.

Some sample links for those 3 media types:

Smooth: http://playready.directtaps.net/smoothstreaming/SSWSS720H264/SuperSpeedway_720.ism/Manifest

RTSP:  rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4

MP4: https://filesamples.com/samples/video/mp4/sample_640x360.mp4

Offline Video Streaming

When offline video streaming, the DUT does not need to be connected to the internet.

DASH Video Streaming

To run an offline DASH video, refer to the following cookbook link: https://www.candelatech.com/cookbook.php?vol=wifire&book=Interop:+Test+Video+Streaming+with+DASH+Server+and+Interop+APK

MP4 Streaming

1. Run nginx on eth1 port by double-clicking on the eth1 port in the Port Mgr, checking the HTTP box circled below, and clicking Apply.

2. Download and place the .mp4 file in the following path: /usr/local/lanforge/nginx/html/

Create a Layer 4-7 cross-connect and add the details pictured below to the Layer 4-7 cross connect. Enter the URL, Source/Dest File, Resource (of the Android mobile), and check the Real Browser and Video Stream boxes.

3. Start Layer4-7 cross-connect and go to Video-View tab in app to observe the running video. Stats can be observed in the Layer 4-7 cross-connect row.
