Some streams play with audio only and incorrect duration #15

While inputstream.adaptive is able to play back this stream correctly, this stream does not work correctly. The latter gives me audio with no video and a totally wrong duration (about 500 minutes instead of the expected 30 minutes).

Note that these streams will only be available for a few weeks and will only work from within the UK.

I have similar issue for example all the video for the gcndex channel suffer the same problem

@CaptainTK I'm unable to retrieve the manifest files.
Can you pls download such an mpd file and attach it here?

Thanks

I can't test right now if the problem is the same for these two, but please see two mpds attached to see the difference between a good and bad one.

After searching in the github history it came out that there was a
similar issue adressed in xbmc#728.

For some reason that piece of code got removed in
xbmc@8889fe9
(in pull request xbmc#883).

The stack trace is from the Raspberry Pi 4 machine. But I can also reproduce the issue
on my x86_64 Linux machine by adding a 1s sleep in the beginning of CdmAdapter::SetTimer.

In order to reproduce it is necessary to quickly play/stop streams.
Script attached at the end of the commit message can be used to ease the reproduction.
In my environment running the script for 1-3 minutes makes Kodi crash.
Although the root cause described in xbmc#729
was a busy loop. Right now address sanitizer reports:

The root cause of the crash is unknown as it comes directly from
libwidevine library. But it crashes when we call cdm->TimerExpired when
the session is closed. After applying mentioned commit I'm not able
to reproduce the crash anymore.

Script to reproduce the issue:
```
set -x

URI='Change it to some uri to play'

while true; do
  curl -s "http://kodi:kodi@127.0.0.1:8080/jsonrpc" -H 'Content-Type: application/json' --data "{\"jsonrpc\":\"2.0\",\"method\":\"Player.Open\",\"params\":{\"item\":{\"file\":\"$URI\"}}}"
  sleep $[ ($RANDOM % 70 + 30) / 10.0 ]

  curl -s "http://kodi:kodi@127.0.0.1:8080/jsonrpc" -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"Player.Stop","params":{"playerid":1}}'
  sleep 1
done
```
