LibVideo/PlaybackManager: Return duration zero when an error occurs

Browse source 
Previously, we would unwrap the duration value even when it contained
an error, causing an assertion failure.

Later, we should change it to return the last known sample timestamp
in the media data, allowing for example live-streamed video to have
a semi-useful duration. In general, though, this is not used by
players in the wild, so we can leave it for now.
