None that I know of for the Kindle PW2.
The Kindles use an "invented by Amazon" video memory layout. And I don't recall reading about anyone doing the work for that model. - - - - Like yourself, I was hoping it would "just work". |

The *nix standard utility, cat (concatenate) reads one or more files, concatenates them, and writes them to stdout. The newer utility, zcat, does the same for files which are gzip compressed. Your problem is not with zcat. The gmplay utility is not coded to handle (I.E: starting with recognition of) your device. Until someone, perhaps yourself, adds that code - it will not work. When launched with KUAL, KUAL should be writing the system error message to its log file (along with just exiting). |

I lost my PW1, so I cannot test recent firmware updates... Also, it has been reported to work on the PW2 as well. My code was future-proofed as far as I could make it back then, and it seems I was successful so far. Last edited by geekmaster; 09-26-2014 at 11:13 AM. |

"Somewhere" - heck, I have lost track of my own posts. Maybe someone will find it for us. Ah, we might be lucky and the PW1 & PW2 will need only minor changes to your code. |

And if I remember right, the extension is broken, and I think that you'd have to be in the directory where gmplay and the .gmv files are for it to work...

Has anybody tested this on PW2 or newer?

"Oh... and I figured out how to get fluid animation (no longer limited to 1.5 FPS) on a DX and DXG now too..." I wish current ME could talk to younger ME and ask him (me) if he wrote that down anywhere... Research I read claims that memories have a half-life of about a year, after which they get pruned or consolidated with other similar memories (i.e. generalized), depending on how much they were used. Makes me wish I was more dilligent at writing stuff down where I could find it again...
BTW, is there a working KUAL extension for this anymore? |

I could never get the KUAL extension to run, so I just ran gmplay in Kterm, with the added bonus of being able to terminate gmplay if I needed to. Someone else might have a working KUAL script.

I just noticed that somebody posted a video of gmplay in operation on a K5:
And it seem that "twobob" (a/k/a "seggie fault") finished adding sound to my gmplay program (he was very close with the "Balsamic" code he shared here before "going dark"): It was nice that they provided a link to this thread in the youtube comments. Hmm... Here is another video somebody else posted, also with sound: Where is the source code (or even a downloadable executable)? Okay, this is by Roman Batyuk (a member here) whose video was very jerky and flashing (non-dithered greyscale). I posted to his thread that he should do dithering like I was doing. He stopped posting here, but it seems he made progress AND added sound: So, both Roman and twobob went dark, but kept producing (unshared) content?

An interesting observation: My video player uses a 130 msec update rate (about 7.7 FPS). I determined that as an optimal speed (as fast as we can go without excess visual artifacts). The docs I had seen at that time said the update rate was 300 msec, so I seemed to be pushing it faster than was its intended speed. However, I just noticed this page at freescale (mfg of SoC with embedded eink controller):
Quote:
When the K4 and K5 came out, the existing firmware and sourcecode first hinted at an animation more, though there was no code at that time to go with such comments. This linked page above says that eink drivers (for newer kindles) now contain (Atkinson) dithering code built into the eink driver. However, the K3 and earlier (and perhaps even the K4, due to its K3 emulation mode used when booting from the main partition) most likely do NOT contain dithering code (though exanimation of recent source code could see if this was added since I last studied the source code in detail).
