Doesn't work in Yandex.Browser (Chromium based)

[theifish]

Yandex.Browser (https://browser.yandex.com/) is a Chromium based browser from Yandex (one of the biggest russian search services). It's very popular in Russia, however Dash.js lib doesn't work correct in the browser.

Environment

• [x] The MPD passes the DASH-IF Conformance Tool on http://dashif.org/conformance.html
• [x] The stream has correct Access-Control-Allow-Origin headers (CORS)
• [x] There are no network errors such as 404s in the browser console when trying to play the stream
• [x] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• [x] The issue occurrs in the latest reference client on http://dashif.org/reference/players/javascript/ and not just on my page
• Link to playable MPD file:
• Dash.js version: 2.1.1
• Browser name/version: Yandex.Browser/16.4
• OS name/version: MS Windows 8

  Steps to reproduce

  1. Open Yandex.Browser (https://browser.yandex.com/)
  2. Open test player page http://dashif.org/reference/players/javascript/v2.1.1/samples/dash-if-reference-player/index.html
  3. Choose any sample and start playing it
  4. Audio starts, but picture doesn't

I found, that MediaPlayer throw an error "Error creating video source buffer."

Observed behaviour

Player doesn't show any pictures.

On Windows 10 and Yandex 16.4.1.8950, at least, the following MPDs work in the reference client for 2.1.1:

• http://dash.edgesuite.net/dash264/TestCases/5a/1/manifest.mpd
• http://rdmedia.bbc.co.uk/dash/ondemand/testcard/1/client_manifest-events.mpd
• http://dash.edgesuite.net/akamai/streamroot/050714/Spring_4Ktest.mpd

It looks like this is specific to Windows 8. Are you running 8.0 or 8.1?

[theifish]

Checked on another Win8 computer - everything works well. Looks like it's my local issue. I'm going to investigate it further.

[wilaw]

@Konstantin – do any of the same samples play in the Shaka player https://shaka-player-demo.appspot.com/ or Bitmovin player http://www.dash-player.com/demo/manifest-test/ ? It could be that the Yandex MSE implementation is at fault if none of the samples at all are playing.

(PS. Thanks for checking all the new submission boxes for the new form. You are the first and we appreciate it!)

Checked with Shaka and Bitmovin players, everything works. Dash.js player doesn't. But again, I can't reproduce the issue on another Win8 machine. Maybe it's only my local issue.

[LloydW93]

Closing since it sounds like a local issue.
