Previously top revealer was set to fixed size, which caused a noticable video tearing along the revealer edge during its animation. This commit removes fixed revealer size, which in turn casues the revealer to cover whole video screen (default behavior), thus eliminates the tearing. Since overlay now becomes the top widget, all player notify signals were reconnected to it.
This adds Kodi-like semi-transparent overlay with current media title, hour and estimated time when video will end. The overlay is visible only on fullscreen mode.
The used GStreamer codecs are picked using rank hierarchy. When there are 2 or more decoders available that can handle the same stream type, the one with higher rank is always picked. This commit adds a function for the codec rank manipulation that can be used for e.g. force disable/enable VAAPI. Should be a neat feature once we have a settings dialog where it can be used.
With this change Clapper can open and load a playlist inside a text file. The text file should have a ".claps" extension and include one media file path per line (path can be either absolute, relative or even a HTTP link).
When a media is changed, normally one would expect to create new radio buttons with video/audio/subtitle tracks names corresponding to current video, but this is inefficient. Destroying objects just to create similiar ones again does take a long time and might lead to memory leaks. That is why a better and faster approach is to simply edit already available objects to match our expectations instead. This commit does just that for tracks radio buttons.
Follow other GNOME apps designs by having fullscreen button on the right side of window header bar. The control panel had too many buttons already and we still need to make some space for playlist. This way "fullscreen" button will be on top bar while windowed and "unfullscreen" button will appear on the bottom right only when player entered fullscreen mode.
Create volume button with popover instead of using GTK provided volume button.
Creating new button with only needed elements is more efficient then removing unneeded items from pre-made volume button. This should also increase performance a little when changing volume, because now we generate new icon only when a change is needed. In pre-made button icon is regenerated on each volume change.
