KinoAmp 0.55

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

Edit: I updated the archives on 2021-08-10 to include the DVDRegion program mentionned in this thread and updated the documentation accordingly.

Changes:

• Added configuration of default language (in audio section).
• Play DVD directly from DVD drive (requires CDFSDriver 2.42 or a SCSI drive).
• Use cell duration for still cells without any still time.
• Fix IFO loading of titles without any menu.
• Support for interleaved VOBUs (like Star Wars opening scroll text in multiple languages).
  These are similar to multiple angles but without support for switching to another angle.
• Fix navigation issue (Star Wars bonus DVD in the photo gallery).
• Fix desync with PCI info causing long delays in menu buttons appearance.
• Fix menu command LinkPTTN.
• Always started with angle 1 even when menu asked to start playing another angle.
  Menu may different button groups flagged for normal, wide, pan & scan and we must use the one flagged as normal.
  Subtitles/menus for widened/pan-scanned versions are overlays of the video in their corrected dimensions and aspect ration and since I just merge the subtitle/menu with the original image I always use the normal subtitle/menu, hence I must also use the matching button group.
• Define separate subtitles for subtitles with multiple delayed set of commands.
  This fixes ‘Le ruban de Moebius’ which fist shows the subtitle as invisible before showing it with its true colors.
• Fix to handle invisible menu buttons:
  Basically, A subtitle is a 4 color image, with 4 transparency levels and with the 4 color codes mapped to YUV colors from a palette of 16 colors stored a title level.
  Now a menu is just a forced subtitle and buttons are rectangles within them that must be displayed when selected in their own 4 transparency levels and color mappings.
  So you just show the button that is selected, right?
  Wrong, you must also show the rest of the menu with his transparency levels/color mappings.
  This allows for menus where you mask/dim everything on the video except for the rectangle corresponding to the selected button by making that button invisible.
• Aspect ratio in DVD IFO overwrites aspect ratio of MPEG stream.
• Fix to display only a single forced subtitle when multiple languages are present.
• Fix for audio remaining muted if no audio in first VOBU.

Note that CDFSDriver 2.42, means basically RISC OS 4.28 (or one of the latest 4.27).
Before that version CD_SCSCIOp is broken. For SCSI drives it is simple to bypass the driver and call directly the SCSI module in order to cope with older versions of the OS, but that is not possible for other drives.

Also, I have only be able to test direct DVD reading with the SCSI drive on my RPi3 so I don’t really know if, even with a working CDFSDriver 2.42, the other CDFSSoftxxx implement correctly SCSIOp.

Hi André

Thanks for the update to KinoAmp.

I have tried it on my ARMX6 and it works with normal/own copied DVD’s but not with commercial DVD’s i.e Star Trek 2009 & Stargate Collection.

It gives a target error – illegal request issue after playing the opening credit.

Take care and thanks for all your efforts on KinoAmp

Update: RISCOS 5.29 3rd Nov 2020.

Can you modify the last line of !KinoAmp.RunKino as

Run Kino:Kino -fKinoChoices:Choices %*0 -d0x20020 2>Kino:log

And post the result of the generated !KinoAmp.log file when using a commercial DVD.
Note: Cut the part between “DVD with xx ifos and xx titles:” and “Cell first play” to reduce the size of the log.

Hi André,

Hope I have cut the log correctly?

Update Ahh Textile stikes again!
Update again – Thanks Chris , lesson learnt

I’m just wondering (longshot) if this is some other type of content protection on the DVD. For example, there was RCE which created an additional layer of region protection, and some recent DVDs have bad sectors as part of their protection (arccos protection?). I believe that programs like AnyDVD on Windows can tell you a bit about what protections may/may not be in used on the DVD.

Does make me wonder – with no OS way to set DVD region, what is KinoAmp doing (or not doing) with regard to region handling?

PS Andre, my apologies for not having time to do testing on this. My ARMX6 is missing its DVD drive, and the workbench has been occupied by other jobs for the last few weeks.

There’s also the very annoying “this TOC has 99 entries that all point to each other” which makes it difficult to extract useful information.
I do wonder how physical DVD players cope while computers fail? Does a DVD drive read more information than a standalone DVD player can?

with no OS way to set DVD region, what is KinoAmp doing (or not doing) with regard to region handling?

The region is not up to the OS, it’s up to the drive. It is available as an option in the OS in order to allow you to set your drive’s region, and I think you can usually change it between two and five times (note – the original setting counts as one) depending on the drive, after which it will be forever locked to the last region it accepted.
Therefore most people will use DeCSS to get around the bull***t region locking – this is commonly done on other platforms using libdvdcss. Or just rip the DVD with Handbrake.

[how I know this: I don’t have a TV any more, I watch stuff on my phone or tablet, neither of which has a DVD player, join the dots ;-) ]

“DVD vs Drive region bits: fd vs 00” indicate that the DVD is region 2 (bit 2 of fd is unset meaning it is allowed for region 2) but drive region is unset (all bit set to 0).

I will check tomorrow if I can get around it.

Hi André

The region issue makes sense as if I remember rightly on Windows the region will be set the first time a new drive is used with a region set DVD.

The drive in my ARM6 was a new one installed a few months back so i guess if it can’t be solved with RISC OS then I will need to put it in to a PC to set the region?

The logging is somewhat lacking but I think that ReportTitleKey fails and when I try to read some sectors to crack the key it fails to read them. Not sure I will be able to bypass region settings.

Can you try this version http://www.riscos-digitalcd.net/image/kinoamp/kinotst.zip and post the logs to confirm my deductions?

Regarding region settings, I had written a little program to alter a drive’ region but lost it when my drive crashed. I will have to write one again.

Therefore most people will use DeCSS …

There is a DeCSS module in Adrian Lees old Cino App. He gives me the sources but I’m to stupid to use.

Private copy is allowed in Germany. So I rip the DVD’s I buy with vobcopy + libdvdcss on Ti Linux. The ripped VOB’s working perfect with KinoAmp.

Can you try this version

Hi André

Snipped log as before but if you need the full log let me know and if I can send it to the address in the KinoAmp help section.

Error has now changed to “Unrecognised Film format”

Can you try this version http://www.riscos-digitalcd.net/image/kinoamp/kinotst1.zip and post the logs?

After the ReportTitleKey error I invalidate the GrantId and get a new BusKey before attempting to crack the key to be sure the session is not maintained in an error state.

If this isn’t working, I don’t know how to put the drive in a state that will allows me to avoid “Target error – Illegal request” when attempting to read protected sectors.

Hi André

The latest test version of KinoAmp still doesn’t play.

I also tried an external DVD drive as well with the same results on the ARMX6.

Thanks for trying.

Private copy is allowed in Germany.

Yes, no, maybe.

It’s the same situation as in France. You’re legally allowed to copy those DVDs (etc) that you own for your own private use…
…but you aren’t entitled to circumvent technical copying restrictions in the process of doing so.

A lot of people know that a lot of people do this, they just don’t make a big fuss about it as nobody wants to be the one to drag the whole DRM issue to court.

Personally, I have exactly zero moral objections to making copies of CDs and DVDs that I own if such copies permit me to listen/watch on the hardware that I typically use (which is quite often an Android device). They supply me with pictures and/or sound on a pretty little spinny disc in return for coin. They do not get to dictate how I use said disc. It I want to watch it in a DVD player, if I want to make an MP4 and watch it on my phone, or if I want to hang the disc outside to scare the crows, that’s up to me.

Added bonus: With some of the cheaper DVDs released in France, ripping also allows me to get rid of the forced French language subtitles that cannot be turned off on a normal DVD player.

Yes, no, maybe.

Also…
The law speaks about an effective copy protection that not allowed to be bypassed. A copy protection that can be bypassed so easily is not an effective one.

I have uploaded http://www.riscos-digitalcd.net/image/kinoamp/Region.zip .

This should allow to set the drive’s region.
I say should because if I tried anything other than 2 (which is its current setting), it first complained that the drive was empty, then with a DVD present with an illegal request error.
I am wondering if the drive must contain a DVD compatible with that region for it to work.

Hi André

Thanks for the Region setting program as that has done the trick as I have set it to Region 2 and I am now played a selection of DVD successfully.

Thanks for all your help.

I have tried to use the DVD playback feature with an ISO (CDFaker 32) and i get “Cannot play DVD: Failed DVD key1 challenge”. Any ideas?

For a protected DVD the player normally needs to negotiate with the drive in order to obtain a session which allows him to read the DVD data. I rather doubt CDFaker implements the commands required.

CDFaker will actually not prevent me from reading the data, so when I have a little time I will see if I can make an ISO of one of my protected DVD and try to make KinoAmp circumvent the session negotiation process.

I should have said, this is an unencrypted DVD of demoscene Amiga demos which is what made the error a bit odd.

Curious. Well, if not encrypted, as a workaround you can always drop the VIDEO_TS folder on KinoAmp, the program will read it without trying to decrypt it.
