Add integrated player

Closes #17

It is currently not possible to manually set the video title used by libclapper, which results in not being able to use ClapperGtk.TitleLabel and an empty/unknown title provided by MPRIS. - solved by injecting a taginject GStreamer element as a video filter

It would be great if it was possible to change the video quality while playing.

Also, in case of Flatpak if you use MPRIS, remember to add its own-name to manifest to it to be able to connect to system bus. Cheers.

This is in fact not needed when using org.mpris.MediaPlayer2.$FLATPAK_ID, which is permitted by default.

Thanks for taking a look at this project!

If you are using GStreamer 1.24 (especially with live streaming), enabling playbin3 might give you better performance and maybe even less issues, see: https://gitlab.com/news-flash/news_flash_gtk/-/blob/57d461a7dc5069c6f49651e7cd022ef82d987105/src/main.rs#L84

Thanks, this helped a lot, especially with previous issues where audio/video weren't properly synchronized.

Thanks for feedback. Even more reason to switch to it by default eventually. Currently it isn't, mainly because it would make minimal required GStreamer version for Clapper be 1.24 which was too new during last release.

FWIW, this now partially implemented in clapper-git - doc here.

Although, we do not get list of available qualities (with their bitrates) from GStreamer yet. Dunno if Mediathek API provides that info. Temporary fallback would be parsing HLS manually to read them. Hopefully this will be implemented somewhere upstream (either in GStreamer or Clapper) in near future, but probably not for next Clapper release yet.

Thanks for letting me know. Unfortunately, the MediathekViewWeb API doesn't provide a HLS URL for streaming with an adaptive bitrate. Instead, there are multiple URLs that point to the full video in different resolutions.

I was thinking about replacing the currently playing media and continuing the video at the same playback position.
