Some streams fail with "415 Unsupported Media Type" #307

dagwieers · 2019-06-14T00:30:31Z

Describe the bug

There is an outstanding issue at VRT NU where some episodes do not work when using HLS streams (i.e. when not using Widevine). The problem has been reported a few times to VRT and they have confirmed this general issue. In most cases they will fix the faulty stream by hand when reported, but the root cause is yet unknown and unfixed.

This relates to #308, #311 and #538

To reproduce

Steps to reproduce the behavior:

Disable Widevine (and restart the add-on)
Go to program 24 hours in police custody
Click on episode S04E05
See error 415 Unsupported Media Type

Fix

Verify this issue on the VRT NU website (Apple Safari?) or in the VRT NU app (Iphone/Ipad?)
Report the stream to VRT NU at: https://www.vrt.be/vrtnu/help/
Do mention the error "415 Unsupported Media Type" and it is related to the HLS stream only.
Wait for VRT to fix the stream.

Work around

Enable Widevine in the settings so the VRT NU add-on selects te MPEG-DASH stream that is unaffected by this issue.

Additional context

michaelarnauts · 2019-06-14T05:45:01Z

I saw this also with an episode of Karrewiet. This also occured on the vrt.nu website. I reported this to vrt and they had fixed this.

This might have nothing to do with the add-on...

mediaminister · 2019-06-14T05:58:04Z

Indeed, it doesn't play on VRT NU website either:
https://www.vrt.be/vrtnu/a-z/appel-d-urgence/2/appel-d-urgence-s2a1/
And this error was reported to VRT NU, but they denied that there was a problem. Unbelievable!
https://twitter.com/bertvandepoel/status/1138232737263960064

This problem only occurs with the HLS-stream, the MPEG-DASH stream is working, when you enable inputstream adaptive, the stream plays fine.

dagwieers · 2019-06-14T06:57:34Z

@mediaminister ~~I did try using inputstream.adaptive though, but maybe something else was wrong. Will try again later.~~ It indeed works fine using inputstream.adaptive.

Should we provide a more sensible error to the user? E.g. try again with or without inputstream.adaptive, try running it from VRT NU website and report to VRT.

Thanks everyone.

mediaminister · 2019-06-14T07:04:42Z

Okay, I'll "fix" this providing a message to the user.
And VRT should fix this problem as explained here: https://docs.unified-streaming.com/documentation/vod/troubleshooting.html#unsupported-media-type

dagwieers · 2019-06-14T12:06:10Z

I added a vrtnu label so we can also track issues that originate at VRT NU. Personally I am a big fan to also track issues here that originate at VRT for the simple reason that we could improve the Kodi plugin (either with a workaround, or with better error messages like we did here).

At some point we will cover most of the common/recurring issues with proper messages so that our users know exactly what to expect (and confidence in our solution stays high despite glitches elsewhere).

mediaminister · 2019-06-20T06:17:46Z

Using Widevine DRM is always a free user choice, for livestreaming and for VOD. The cause of your problem was definitely the DRM option, I overlooked that. I improved the stream error message accordingly in: #332

mediaminister · 2019-06-26T21:18:55Z

Already four episodes of Appel d'urgence are affected and VRT didn't fix this yet...

mediaminister · 2019-06-28T05:20:48Z

Okay, VRT NU fixed this yesterday.

dagwieers · 2019-10-23T09:19:31Z

I reported another issue related to HLS stream playback (episode S04E05 of 24 hours in police custody) and VRT confirmed they still have intermittent issues related to this that they are trying to get fixed, so it still may happen from time to time...

mediaminister · 2019-10-23T12:43:47Z

VRT NU uses Unified Origin and HTTP Error 415 is documented, only VRT NU can fix it: https://docs.unified-streaming.com/documentation/vod/index.html

dagwieers · 2020-02-02T02:37:21Z

So we discovered that the VRT Radio2 live stream also suffers from this issue:
#685 (comment)

I opened a dedicated ticket for this at #735

dagwieers · 2020-04-10T00:19:02Z

This happened again last night on the latest De Afspraak episode (2020-04-09).
https://www.vrt.be/vrtnu/a-z/de-afspraak/2020/de-afspraak-d20200409/

I reported it to VRT NU.

mediaminister · 2020-04-10T08:32:24Z

This time only the MPEG DASH stream failed, HLS was fine.

This means Inputstream Adaptive detects the HTTP 415 error, but as far as I know there is no interface to catch the error in Python and show an error message to the user...

dagwieers · 2020-04-10T12:28:14Z

We cannot easily handle this better. We handed this over to IA and any conceivable way to check playback is worse than the problem IMO.

mediaminister · 2020-04-10T13:35:29Z

If xbmc.Player.onPlayBackError could return http errors, then it would be easy to automatically select the HLS stream if MPEG DASH failed.

dagwieers · 2020-04-10T14:19:54Z

Can we make a new ticket for this?

This might also be the right way to handle Widevine issues. There is a missing link there too that we can have add-ons support through inputstreamhelper.

Update: I opened #727 for this. Now we need to report this upstream.
