Variants that can be played are being removed when useMediaCapabilties=true

[caridley]

Have you read the FAQ and checked for duplicate open issues?
Yes

What version of Shaka Player are you using?
master branch commit 4c97562

Can you reproduce the issue with our latest release version?
no problem does not occur with 2.5.20 or 3.0.10

Can you reproduce the issue with the latest code from master?
yes

Are you using the demo app or your own custom app?
custom app

If custom app, can you reproduce the issue using our demo app?
no - not sure how to run demo app with master branch code

What browser and OS are you using?
problem was observed on chrome with a mac and on a 2017 Tizen TV

For embedded devices (smart TVs, etc.), what model and firmware version are you using?

What are the manifest and license server URIs?
https://dluxvod.spectrum.com/DASH_DRM/XPMV0001609509701001/out.ism/manifest.mpd
https://pi-lite.spectrum.net/licenseServer/widevine/v1/twc/license

Note that license request will fail, but the problem can be detected before the license request occurs.

What configuration are you using? What is the output of player.getConfiguration()?
see player-config.json in the attached shakaMissingVariants7LQN.zip file

What did you do?
Play the asset with useMediaCapabilties=true in player config

What did you expect to happen?
All 5 variants can be used

What actually happened?
Only the 2 lowest bitrate variants can be used

With shaka source code and the debugger I determined that the other variants were being removed by this function shaka.util.StreamUtils.filterManifestByDrm()

When useMediaCapabilties=false the problem does not occure.

config, manifest and log can be found in that attached file shakaMissingVariants7LQN.zip

Hello @caridley , thank you for reporting that!
The link of the license server URI looks invalid with our demo app. Would you please confirm that's available for testing? Thank you!

@michellezhuogg I don't have an account that I can share with access to that stream at this time, but I think you will find that you can observe the problem without a valid license URL, by setting a break point in shaka.util.StreamUtils.filterManifestByDrm() where the variants are being removed prior to making any license request.

@caridley Thank you! I verified that, and will work on improving that.
