ECCP does not work properly #165

Closed tobbee closed 4 months ago

tobbee commented 4 months ago

From @dsilhavy on DASH-IF slack:

I generated a stream with ECCP enabled: https://livesim2.dashif.org/livesim2/eccp_cbcs/testpic_2s/Manifest.mpd. Two questions: I am getting CORS errors when testing in https://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html. It looks like the preflight request to https://livesim2.dashif.org/livesim2/eccp_cbcs/testpic_2s/eccp.json fails Even without a valid response from https://livesim2.dashif.org/livesim2/eccp_cbcs/testpic_2s/eccp.json the playback still works. Shouldn't this fail as we dont have a valid key for decryption.

Response from @tobbee

Thanks for your feedback. I missed the CORS errors since I used dash.js via livesim2 that proxies the code so CORS is no issue. That should be a quick fix. The other bullet makes me believe that the segments are not properly encrypted. I got a similar experience when using Safari which complained about the keys, but played the segments. I think that Safari does not support ClearKey, so the playback should not be possible. Is that your view as well? I just checked, and the segments do not include any encryption boxes, so the encryption never happened. Will fix that, of course

Still some CORS issue with v1.2.1, so need some more debugging...

Fixed in v1.2.2
