VNIS Video Stream ensures that your video streaming will have zero downtime and will scale during demand spikes. This is possible due to VNIS Video Stream's mid-stream CDN switching and P2P video delivery.
If you are using Tencent Video on Demand (VoD), it is possible to improve the availability and scalability of your HLS videos by integrating them into VNIS Video Stream.
The diagram and instructions below will show you how you can do this.
Step 1: Obtain the m3u8 URL from Tencent VOD
You need to ensure that your videos are transcoded to HLS format. Check this article to learn more about video transcoding and Tencent VOD.
Log in to your Tencent VoD account, then navigate to ‘ Video/Audio Management’.
On this page and under the ‘ Uploaded’ tab, select your target video and then click ‘Quick view’.
Under the ‘ Video URL’ section, you can copy the m3u8 URL of your target HLS video by clicking the ‘Copy URL’ (e.g. http://1307357694.vod2.myqcloud.com/51529ed6vodtranshk1307357694/29a96172387702307772331755/v.f100210.m3u8).
You will need this m3u8 URL in VNIS Stream.
Step 2: Set up Live Stream in VNIS Video Stream
To set up a live stream, navigate to ‘ Stream’ > ‘Live Streams’, and then click the ‘Create live stream’ button.
On this page, set the Stream detail info.
The Stream detail info includes:
- Stream source name: a unique name for the stream source (e.g. ss name)
- Protocol: specify the video format/container of the video stream. For now, only HLS is available.
- Origin server: the origin server is where your video streams are hosted. Use the domain name associated to your origin server (e.g. example.com). You may also set this origin as a ‘CDN candidate’ and by doing so, this server will be used together with other CDNs for mid-stream CDN switching.
Next, set the CDN configuration.
The system will recommend you to install 2 Basic CDNs by default, namely Cloudfront and Alibaba Cloud. You may also install additional CDNs depending on your business strategy.
You can add up to a maximum of 10 CDNs per stream source. If you set your origin as a CDN candidate, then your origin will also be counted as 1 CDN.
You may also enable P2P video delivery and/or Domain allowlist.
Finally, click the ‘ Create live stream’ button.

Step 3: Paste the m3u8 URL to the VNIS SDK
After creating a live stream, VNIS Video Stream will generate code snippets.
Go to the ‘ Install & Test’ tab and paste the copied m3u8 URL on the ‘Playlist URL’ field (from Tencent VOD), and then click the ‘Insert’ button.
This process will insert the m3u8 URL of your target HLS video into the code snippets of the SDK.
You may check the preview of your video on the ‘ Video Preview’ tab and by clicking the ‘Preview’ button.
You can click the ‘ Copy’ button to copy all the code snippets into your streaming app code. You can also open the ‘See our docs’ link, to check more detailed instructions on how to input the code snippets for different players and JS frameworks.
