can't playback a second video

install it with "pkcon --allow-untrusted install-local com.ubuntu.camera_3.0.0.400_armhf.click "

I did some tests and I can confirm that. The application is requesting the MediaPlayer component to play the new file, but for some reason the low level library is not working correct.

marking invalid for mediaplayer-app as this code has not changed and was working up until recently. something in mediahub or other part of the stack changed to cause this regression

could be the same root causes that is causing this bug as well?

Just confirmed this is still an issue with image 104 (rtm - krillin). It fails even if you try to play the second video without the first one completely finished (moving back to the video scopes trying to open up the second video).

Works fine with image 72 (rtm - krillin), but then on image 73 I can't even play the video (mediaplayer-app will not even start). I can play the video with 75, but then I have the same issue as described by this bug.

Quite a few landings on both images, and both including media-hub.

Sorry, media-hub is only at 75, the other changes in 73 are just responsible for the video not playing at all.

So it might be a regression with the huge landing we had on media-hub, the one that ended up bumping the api version to 2.

The following always reproduces it for me:

1. Play a video from the scope
2. Swipe back to Unity which pauses video playback and suspends the mediaplayer-app
3. Play a second video from the scope, observe that it brings up mediaplayer-app but the video does not play

This method always plays:

1. Play a video from the scope
2. Tap to bring up the toolbar in mediaplayer-app, press the left arrow button to return to the video scope
3. Play a second video from the scope, observe that it brings up mediaplayer-app and plays the video

The second method works because it actually kills mediaplayer-app when you tap the left arrow. The first method only suspends and reuses the same media-hub session.

After tracing this -- the media-player app does not properly convert the URI it is sent by the scope.

you can see in the media-hub log

The URI is only converted when the app is launched and passed via command line.
