NEW: Blu-ray Menu playback support
jmone:
Hi Hendrik - Very happy with the BD/UHD support, it all just works, though I notice there has been lots of activity on the libbluray git over the last few months but don't know if any of this makes much of a difference for MC?

Hello all,
I've just signed up here to post this. I never knew about JRiver Media Center, despite having done extensive searches for software media players that supports BD-J. I have searched for these players in order to list them as supported players for my BD-J projects.
Most of the activity you see on github about libbluray is my doing.
I'm a sparetime hobby BD-J developer, and therefor use software players a lot for testing. Primarily VLC but also Kodi.
I have ported an old J2ME game of mine to BD-J and also created "8-bit Memoirs"; a diskmag-like Blu-ray eBook. Currently working on my 2nd BD-J game.
(BD-J homebrew games are fun to make, because they run on PS3 + PS4 + XB1 from the same disc).
I send a lot of feedback to the devs of VLC, Kodi and libbluray, and I'll be happy to do the same for JRiver Media Center, provided I can have a Linux version for free to test on.
My BD-J Xlets are nice for testing because they're free, legal, small in size and unencrypted. My BD-J Xlets are also tested on a lot of different hardware players to make sure they run on the real deal - so you can count on them staying within specs.
Here are some general points I have also posted to VLC and Kodi devs:
* According to Blu-ray specs, all Blu-ray players must have a POPUP MENU button. This seems to be overlooked by most software media players. The POPUP MENU button is not the same as the TOP MENU button (which is called MENU on a DVD remote control). A Blu-ray remote control has both a TOP MENU button and a POPUP MENU button.
The POPUP MENU button usually used to bring back the menu while the movie is playing. KeyCode for POPUP MENU is 461.
* A BD-J Xlet can request to use certain keys on the keyboard. MC should check this, and give up any native shortcuts there might be for this key, to the Xlet if it requets to use this key.
* Some media players slow down FPS tremendously if no video is playing. But for a Blu-ray, an Xlet may still be running - either make a check if an Xlet is running or else don't slow down FPS at all.
Other stuff
* libbluray 1.2.0 will have mouse support and better key controls (separate KEY_PRESSED and KEY_RELEASED events) - so it would be a good idea to add this in MC too.
* "Funky Fresh" is a cool BD-J scene demo that can also be used for testing.
* Same goes for "Metal Skin Slidetro".
Hendrik:
Thanks for the information. Our Blu-ray support is based on libbluray, so eventually such improvements would also reach us, although we won't be updating our copy on a daily basis.
To some of the more concrete points:
- We support both menu keys, and you can access the functionality through various means, either by mapping the second menu key to a remote control key, or a keyboard key, or use it through the context menu. Typical MCE remotes don't have such a key, so a default mapping is hard to provide for us. Instructions for mapping the key are in the first post of this very thread.
- We try to do our best to detect interactive Xlets and give them keyboard focus as appropriate.
- If an interactive xlet is drawing on top of a static background, we don't use a fixed "FPS" as such but just redraw whenever the xlet updates the graphics plane. Not sure how well this would work with a game, but I imagine it should be OK.
On a final note, unfortunately our Blu-ray support is currently limited to Media Center for Windows. The feature has not been ported to Linux or Mac yet, because we use two different video engines for Windows and Linux/Mac.

I see. Slightly off-topic then, but: I don't suppose you know if Media Center runs on Linux with Wine?

Perhaps it is more correct to turn my problem https://yabb.jriver.com/interact/index.php/topic,120578.msg845797.html#msg845797
here: is it correct that manually setting in video settings my receiver as audio renderer the film stops in menu mode activated?
In essence it fails to hook up audio in bitstream mode.
If it is correct I put my soul in peace.
