Live Video Streaming Support
Streaming Sites and Protocols Supported
Under the hood, we use an awesome software called Streamlink. It currently supports:
- several streaming protocols, including HLS and HLS variants, HTTP, RTMP and others
- a large list of live video streaming sites, like YouTube Live streams, UStream streams, DailyMotion, and others
IMPORTANT: The Yodeck Player does not yet support automatic selection of streams based on available bandwidth. So, even if the stream of streaming site provides multiple resolutions or quality levels (bitrates), the Player will only select the highest possible level. We will soon support selecting a quality level between, "worst", "medium", and "best".
How to add a Live Video Streaming Site
If you select to create Live Video Streaming, you will be presented with a text field asking for the URL of the video. Just paste the link from the site in that field. For example, here is the video link from CNN News live stream on YouTube:
https://youtu.be/nXc8eiAFc3U
Just copy this address and paste it into the text field when creating a Live Video Streaming entry in Yodeck.
How to add a Live Video Streaming URL (e.g. HLS)
Note that this is an advanced usage of Live Video Streaming feature. You can contact our Support Team in case you need help.
Specifying the Video Stream URL
If you select to create a Live Video Streaming, you will be presented with a text field asking for the URL of the video stream. You need to put the exact stream URL, prep ended with the protocol prefix. For example, here is the HLS video stream link from NASA live stream (an HLS Variant playlist, with multiple version of the stream):
hlsvariant://https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master.m3u8
Specifying a specific Stream from a HLS Variant Playlist
The above playlist file has the following contents (you can download it with a web browser):
#EXTM3UThis HLS Variant Playlist provides 3 different quality levels on 3 distinct HLS streams. By default, the Yodeck Player will always select the stream with the best quality level. If you want to select one specific stream, you will need to use one of the above listed distinct HLS stream URLs:
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=2340800,AVERAGE-BANDWIDTH=2340800,CODECS="avc1.4d401f,mp4a.40.2",RESOLUTION=1280x720
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_2000.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=910800,AVERAGE-BANDWIDTH=910800,CODECS="avc1.4d401f,mp4a.40.2",RESOLUTION=1280x720
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_700.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=620400,AVERAGE-BANDWIDTH=620400,CODECS="avc1.4d401f,mp4a.40.2",RESOLUTION=1280x720
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_500.m3u8
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_2000.m3u8For example, to specify the mid-level quality stream, you would enter in the text field of the Yodeck portal:
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_700.m3u8
https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_500.m3u8
hls://https://nasa-i.akamaihd.net/hls/live/253565/NTV-Public1/master_700.m3u8
The same should be done for any HLS video streaming source in order to select a specific quality level, that is to use the specific HLS stream URL instead of the overall HLS Variant Playlist URL.
