Just a thought.
I e-mailed you a patch that fixes an option parsing error in Xephyr.

There's a trailing comma in the KUAl extension, so the breakage is to be expected, but it definitely *shouldn't* be eating the KUAL menu in the process... o_O.

a way around the 1.5 FPS for kindle DX?

In the "Geek techno" section of the updated original post, the last line says there is a way around the 1.5 FPS for kindle DX.

I tried to take a cue from another thread here (http://www.mobileread.mobi/forums/sh...=148581&page=7), and have multiple updates launched in parallel, each update on its own thread. The gmplay modified by me sent all these requests and got a theoretical frame rate above 1.5 per second, but there was no improvement on the visible output.

So what is *the* approach? I'm willing to spend time coding and reporting results, but I'm stuck for the moment.

The Kindle touch eink screen actually "autodithers" in Hardware when put in the right mode. no it doesnt... that was a mistake on my part. In fact the VLC player notices the need to dither and implements it. Go figure..

perhaps via https://www.mobileread.com/forums/sho...d.php?t=206917

and
mxcfbUpdateData.flags = EPDC_FLAG_FORCE_MONOCHROME;
mxcfbUpdateData.update_mode = UPDATE_MODE_PARTIAL;
mxcfbUpdateData.waveform_mode = WAVEFORM_MODE_A2;

(or the DX equivalents)
you could achieve a faster native update speed as the dithering in one of those "contrast" settings is most certainly "single bit" -

And then split the updates into the various sectors of the screen (I assume this is what you have done, the 2nd part)

With regards to your actual question...
As far as I know Geekmaster never stumped up that info of which you speak.
I too have longingly read that post a few times...

I believe he occasionally picks up his PM's from time to time, but I couldn't swear to it...

Hunting around in the relevant freescale header and seeing what is truly hardware possible is most likely the best bet...

Not an answer as such but hopefully a route to a solution.

EDIT: actually... thinking about it... how big is the virtual framebuffer on that thing?

eips -i

assuming it is 3 times bigger one could write to the off screen area and use the "pan" function to triple the visible rate... perhaps that was it?

No off-screen space for DXG either, it seems. There seems to be enough space for two 800x600 screens. Wonder if I could use that (paint, pan then rotate)

Nothing happen in paperwhite 2. By the way, which video format does it support? I am just user, not developer. So, i dont understand some of the posts. I installed it, and open from KUAL. Nothing happen in pw2.

I just want to watch eye exercise video in my kindle.

This code is brilliant geekmaster!!! A question though: as you said, in K4 main the eink is from K3. Based on this, I guess it's possible to bring eink from K5 or K4 to K3, am I right?

And this would resolve the issue of burning CPU for playing video or anything with heavy processing involved. Eh?

P.S. Oh boy, why didn't Ehhh from the other thread share his code!!! Ahhhh... it would make it a lot easier for integrating sound!

My code supports all the eink kindles in main and diags modes, even the PW with no changes from K5 (but not centered in the higher resolution). I only have a PW1, so if it does not work on a PW2 they must have changed something, and I will need a PW2 to test it. Probably some little change should fix the difference so it works too. Was it tested in diags mode?

Not much time now. I have a bunch of multi-millionaires wanting my time (knowing my time is worth $400 per hour). They are sending me to tradeshows and stuff, making introductions to VIPs in the tech industries, putting money in my paypal account to buy prototyping parts and supplies. A project mixing VR, robotics, gaming, and social networking. I am becoming world famous in the tech sector now. My OLD world-wide fame faded decades ago. At age 60, I am about to start the second half of my life.


I may get back to this if I get bored. For now, email tells me when some threads are posted to here. A site mod gave me about a million in karma for posting here again awhile back, putting me in the lead again, so maybe they think that my being here may bring back some of the traffic that disappeared after I got more active elsewhere (about 10,000 informative and helpful posts). Yeah, people call me a god over at those forums too. I hate that! I do not want to get tacked to a cross, burned at the stake, or lynched! I cannot help it that shrinks said parts of my intellect are too high to measure... But I am vulnerable to predators and dishonest people (most of the same skills and weaknesses as people with Asperger's except with exceptional math skills too, like some idiot savants). Not better than anybody. Just different, perhaps very different (wrongplanet.com different). Everybody is my equal, homeless people, corporate leaders, and kings...

The corporate VIPs from Sony are wondering why I got put in line in front of them at an important function (I was recognized as a VIP more important than them) and they were highly upset. You know, the usual stuff... I am one of the guys with mismatched socks, generous and innocent to a fault, that places like IBM keep in the back room so we can solve the hard stuff, only bringing us out to mix with ordinary folk to quickly solve a problem "normal" experts have been stuck on for a long time. We distract easily by anything of interest, so we are isolated to keep us focused without distractions. Some of us do indeed have Asperger's Syndrome, but I remain undiagnosed. I learned from my father just yesterday that part of my brain may have been damaged at birth, so it grew an overly-high intellect so it could replace the damaged hardwire-reflex stuff with software algorithms running in my "Spock brain" consciousness. Weird, eh? But apparently true...

BTW, the founder of Oculus (just bought by facebook for two billion dollars) wants me to send him my life story, and he said he will read it. Now I just have to write it! I met John Romero (used to be John Carmack's partner), and I am meeting lots of other famous people and getting lots of respect (some literally bowing to me for goodness sake -- it is embarrassing). Kind of unbelievable even to me. I did not know showing my real face to people would make such a hit with all my geekmaster contributions in the VR forums... A true celebrity hugged me and said "nice to meet a fellow celebrity". Hmm...

Good luck guys, and keep on having fun! I still want my eink wall, so I will be back here some day! TTYL

EDIT: I was asked to be CTO at an interesting start-up company that converges on a lot of my interests and experiences, so I could be a perfect fit. In fact, our plans seem to basically revolve around my own ideas, so I hope that leads somewhere nice that can enhance my life savings nest egg. If this doesn't work out, I may regret telling the SpaceX guys they cannot afford me when they said I will be a "perfect fit" with them (I am not interested in Rocket Surgery at the moment). The guy who just got two gigabucks from facebook told me face-to-face that he wants to read my life story, and now some publisher wants it too, so my wife says I should write down some stories from my life every day -- it could take decades (my "condition" makes me so precocious, curious, and takes me places others fear to tread, giving me far too many stories to tell)... I really need an audience while telling my stories, because the words I choose depends on the expressions on their faces). Writing them will be hard and lacks the feeling of companionship I have while telling them in person... Socializing is hard, but people love hearing my stories and beg for more... Where to go from here? Sadly, I have to be really hungry all the time (calorie restriction diet) if I plan to stay healthy the next 60 years of my life...

I posted some news from my life above. Oculus VR closed their public forums PROBABLY because of all the jealous negativity being spewed there after being acquired by facebook. Now I cannot share with my friends there, and I lost access to a large external piece of my mind I had stored there. I hope they get those forums disinfected soon, and get them back online. I also hope such negative forum posters do not follow me back here...

Comments are welcome, but please be gentle. I have simple but sensitive feelings. Thanks...

EDIT: Those forums are open again, with many people complaining of password resets, so perhaps a security breach. I hope no credit card data was lost to the script kiddies. Two billion dollars in new funds attracts predatory hackers.
