Tizen app is not caching video files from the HTML page

Issue summary: 

  • Cache-Control headers for video files on the HTML page ignored
  • Requests to video files are bypassed and do not reach the Service Worker 
     

Case description:

We made a Tizen Web App for TV that receives the URL and plays it in the iframe. In the iframe, we load a page with a slideshow (images and videos). 

 

After some testing, we noticed that regular browser caching(Cache-Control headers) is not working, which creates huge traffic. With 3 small (5 MB videos), we have got something near 1Tb per day if we keep it to play for 24h.

 

Trying to overcome this issue, we have created a version with a Service worker what did a precaching of all images & videos for the slideshow. But it works for all requests except requests to video files(mp4, WebM). 

Somehow video files are bypassed or processed differently by the Tizen browser.

 

Here is a summary of what we have already tested with no luck:

  • Set headers "Cache-Control: max-age=31536000"
  • Use Service Worker to precache and serve video
  • Place just one <video> on the page and 
    • Set loop attribute
    • Call .play() every 10 sec.

The result is the same for all cases => video(s) loads over the network every playtime.

 

Please advise how to get caching working for video or any alternative workaround ideas applicable to this case.

If you use your Samsung TV to access the internet, you can also clear the cache in your TV's built-in browser. To do this, open the browser and go to the “Settings” menu. From there, you can select “Clear Browsing Data” and choose to clear the cache

This makes sense.
