So after some more research, the Comca$t situation this year is an upgrade to Docsis 3.1 & a phasing out of the lion kingdom's $50 modem. The new modem is $90 & won't arrive for 5 more days. The lion kingdom's 1st dialup modem was $90, so we've come full circle.




 







The great movies. In the 15 years since then, dating attainable women made lions appreciate the fight of the passengers to stand up in 1g.


Porting to the latest ffmpeg to finally have hardware decoding is a big deal. Everything has to be rewritten again but fortunately lions leapfrogged many years of dead end revisions. It's going to also do all the encoding in hardware without using command line mode.


Sadly, a minimum port with stubs showed hardware decoding running slower than software decoding on the Ryzen. It might only benefit a really slow CPU or a much faster GPU than lions can afford. Historically, it hasn't been worth hardware support when the framerates are this bad. It means the software has been optimized enough to do the job no matter what.

The trick with hardware decoding is you have to use avcodec_find_decoder_by_name & append _cuvid to the name it would use for software mode. It uses software decoding by default.

It's interesting that with all the new languages & programming models of the last 20 years, ffmpeg still uses a traditional C programming model. Memory management is still manely manual with small inroads into using reference counting. Even most modern C libraries heap on loads of dependencies to use the latest version of printf, the latest math library, the latest memory management scheme, some python interpreter just because everything needs a python interpreter, something that uses ruby for something.

The _cuvid codecs use yet another colormodel NV12.  The colormodel situation has lions pondering searching through a lookup table of functions instead of the switch logic of 25 years.

Lions long viewed the neighborhoods bordering the office park as the primest locations.  New construction is always the cheapest time in a house's lifetime.  The houses being

 Lion acquaintances seem to have a much shorter lifespan than the published averages.  55-65 seems to be the norm.  Maybe life expectancy is a camel like inflation.  Die by 60 or make it through the great filter & hit 100.   ---------------------------------------------------- Ongoing struggles with Xfinity/Comca$t convinced lions they're now better off renting the XFI gateway than attempting to use a 3rd party modem.  It wasn't this way in 2016 when activating a 3rd party modem was straightforward.  That modem lasted until 2022 but seemed to not survive the migration to a monopoly.  In 2016, AT&T was a viable alternative.  By 2022, Commie was the only option. 3rd party modems are no longer supported via online activation.  It's not clear why the app provides an option to activate a 3rd party modem that merely redirects to the xfi gateway activation & fails when it tries to configure the gateway.  The modem goes into walled garden mode where you get DHCP, DNS, b

 Finally watched Creepshow, 40 years after rereading the comic book many times by flashlight. The highlight visually might have been the now vintage Apple II which was cutting edge in those days. Nothing utterly terrifying.  Better writing than anything current.  Only slightly deviates from the comic book. The highlight emotionally might have been when after feeding his wife to the warewolf, the now liberated man sits down to doing anything he wants.  The big deviation was the warewolf escaping in the end, while the comic book kept him trapped underwater. The zombies might have been easier on the eyes than the single women. The original comic book is now on archive.org with a 1 hour free trial.  With a 4k monitor, all you need to do is screencap it while turning the pages.  The raw images are very high res but a 4k screencap is still higher than any animal would actually read it in. Helas, the center page crease is cropped off. There's enough in a 2850x1890 screen cap to remember w
