Video Thumbnail questions

Jeroen Geldhof [SLC] [DevOps Enabler]5.38K 7 days ago 0 Comments

Temporarily, I am exporting via SFTP the HLS stream from my TAG server to the DMA. It exports the .jpg and u3m8 files continuously.

I have created sub-folders in my Video Thumbnails folder where it is exported to and explicitly added these folders to the web.config:     <add key="ExtraAllowedPaths" value="/TAGVS/;/VideoThumbnails/" />

I added the file .ts and .u3m8 extensions to the IIS config.

My two issues are:

  1. Until I have my HLS transcoder server setup, I want to run the DMA as a proxy to itself. i.e I want to use the DMA only as its own source and thus be able to run video thumbnails – both Generic Images and HTML5-HLS source.
    1. So far, I only have proxy=false working for my Generic Images. No success with HLS at all or proxy=true for images.
    2. The DMA is HTTPS and URL based.
    3. I can access the (proxy-false) files directly from the Edge and Chrome browser, but only the same URL that works in the Visual Overview (Images/Proxy false only)
  2. My video thumbnails that do work are only fixed in size and don’t resize/scale to the Shape on the Visual Overview.

Any thoughts?

Following is the answer provided by the experts.

Please find some additional details regarding the VideoThumbnails feature:

  1. The VideoThumbnails feature does not natively proxy HLS streams. If the browser cannot directly access the .m3u8 or .ts files, you need to run the separate HLS Proxy service (Node.js-based) on the DMA. You can then use the URL generated by that proxy.

  1. Starting from DataMiner 10.4.0 [CU18] / 10.5.0 [CU6] / 10.5.9, you can control how pictures or videos are rendered inside a shape using the fitMode parameter. This allows you to define how the content scales within the shape.
