KinoAmp 0.56

The new version is available from http://www.riscos-digitalcd.net/image/kinoamp/kinoamp.htm

Changes:

• Added on screen controls, shown when moving the mouse, useful for full-screen mode.
• Added neon YUV to RGB conversion routines, effects mainly noticable on Full-HD streams.
  On Pi3, 16-bit routine is about 25% faster, giving an overall fps increase of 20%.
  On Pi3, 32-bit routine is about 10% faster, giving an overall fps increase of 10%.
• Fixed (bi)linear scaling of ARGB15 and ABGR15 modes (i.e. 32K modes with 1-bit alpha channel).
• Added neon 16bpp (bi)linear scaling routines, highly noticable on scaling DVD to Full-HD.
  On Pi3, the routine is about 60%, giving an overall fps increase of 50%.
• Added neon YUV to YV16/YV12/NZ12/NZ21 conversion routines (overlays).
  On Pi3, the routine is about 250% faster, giving an overall fps increase of 20%.
• Fix DVD commands. Arithmetic is saturated.
• Fix DVD commands with resume cell.
• Fix DVD JumpSS_VTSM command (title part).
• Improved window resizing and size toggling.
• Fix issue where OSD is initially redrawn on background instead of overlay.

Nice! Thanks Andre’ :)

I saw that you’ve added a lot of DVD support recently. I’m in the process of setting up a new Raspberry Pi 4, with a nice USB DVD drive. It was supplied to me with 0.52 of KinoAMP installed. I wasn’t too surprised that non of the commercial DVDs worked. An amateur DVD of a school play worked fine, though.

Having upgraded to 0.56 the menu for the DVD now displays, but unfortunately, although the menu offers two options, Play and Scenes, I don’t seem to be able to select either with the mouse. Instead the animation of the menu backdrop stops/starts each time I click. Would it be helpful if I can send you the appropriate files as an example so you can improve the support. If so, which ones do you need?

One of the commercial DVDs now gets as far as playing the distributor’s little sequence, and then a scrolling copyright statement. When it gets to the end of that, where you might expect a DVD menu, it crashes the whole machine and only a power cycle gets out of this. Is this to be expected with such DVDs? I read in an earlier help file that KinoAMP does not support encrypted content, but I don’t know enough about DVDs to know if that’s basically all commercial DVDs.

Hope this doesn’t come over as critical, by the way. It’s great to have KinoAMP: thanks for all your work on it. A few years ago we chose a digital camera that recorded MPEGs on the basis of being able to play them back on RISC OS. With the Raspberry Pi 4 the quality is much better.

At the moment menus are only handled from the keyboard (arrows and return key).

Unprotected DVD can be read by simply by dragging the VIDEO_TS folder to play them but for protected DVDs, you need select the drive to play by selecting the drive’s from KinoAmp’s iconbar menu. This is required because it needs to negotiate with the drive’s to be able to read the protected parts and obtain the keys for decrypting the data.

One ther thing to remember is that the DVD drive may not have it’s region set up so make sure you use the supplied program, within the 0.56 download, called DVDRegion to set this.

If the region is not set up in the DVD firmware then it can cause issues with playing certain restricted DVD’s and/or lock up RISCOS.

Thank you for the tips, both of you. The region did need setting up on the drive, and I hadn’t realised that I needed to select the drive from the iconbar menu. I’ve tested a couple of commercial DVDs and everything is working nicely. Very impressive!

Now I just need to see whether I can get the choices set up so that a film played full screen on a 5:4 ratio monitor doesn’t come out with everyone looking too tall and thin!

KinoAmp assumes the display always uses square pixels, so if instead you monitor stretches all resolutions to fill the screen, use a full screen resolution that matches the 5:4 aspect ratio
