04:47 mr_lou pdurbin, I'm still curious to hear about platforms that can live up to all my other wishes.
05:04 Loonifer joined ##friendlyjava
05:39 mr_lou Time to go to work. Later.

18:33 aditsu mr_lou: well, any cross-platform language/framework that can handle video and audio can help .. how about python? :)
18:40 mr_lou aditsu, So you'd create an executable for multiple platforms?
18:40 mr_lou Why not use Java then?
18:41 aditsu you already considered java and it already matches pretty much all your other wishes
18:41 mr_lou Except it would still be a 24 gb download.
18:41 mr_lou - which many people complain about.
18:41 mr_lou They want it to be an online thing.
18:42 aditsu embed youtube videos :)
18:42 mr_lou With Kodi v18 it can be an online thing without requiring any additional work.
18:43 mr_lou Nah, don't want to use different services.
18:43 aditsu then stream from your site
18:43 mr_lou Yea... but might as well just refer to Kodi then.
18:44 mr_lou It's already set up actually.
18:45 mr_lou You simply play the Blu-ray from a remote source.
18:46 aditsu ok, I was just giving you alternatives
18:47 mr_lou Most important criteria: It must continue to work 50 years into the future.
18:47 mr_lou Impossible to achieve with a website.
18:48 aditsu are you sure blu-ray videos will be playable 50 years in the future?
18:48 mr_lou Blu-ray will work, just like a modern media player still handles very old formats. (A Blu-ray player still supports VCD).
18:48 mr_lou Absolutely they will.
18:49 mr_lou Just like emulators of various retro computers will continue to be able to play Z80, DSK, ADF and D64 files.
18:49 mr_lou There will always be software media players that can handle Blu-ray ISO files.
18:50 mr_lou I'm up for a bet if you are. ::-) Then we can meet back here 50 years from now. ;-)
18:50 aditsu right.. you'll have to rely on a dwindling group of unpaid enthusiasts who still have an interest in ancient platforms, and if you're lucky, you will get *most* things to play right
18:51 aditsu I think there are already dos games that can't be played right anymore
18:51 mr_lou There will always be enthusiasts. Just look at the number of different emulators for any retro computer. It's crazy. DOS games are easy: Just install dosbox.
18:52 mr_lou And once the various media players have  included support for Blu-ray, why remove it again? Once it's there, it'll work forever, because it's a dead platform.
18:52 aditsu dosbox doesn't behave exactly like an old computer.. I've had some issues
18:53 aditsu some media players will die out, others will likely need to be rewritten
18:54 mr_lou True. But I don't think we'll see any such big changes within the next 50 years.
18:55 mr_lou It'll be easy to find cheap used Blu-ray players too.
18:55 mr_lou Just like you can buy a ton of cheap VHS machines nowadays.
18:56 mr_lou 8-bit Memoirs can't die.
18:56 mr_lou ;-)
18:58 aditsu also see https://xkcd.com/1909/ and https://xkcd.com/1683/ :)
18:59 mr_lou I know that first one. And that's exactly why I refused to use web.
18:59 mr_lou 8-bit Memoirs is a book.
19:00 mr_lou Using web would be really stupid.
19:00 mr_lou It had to be a "dead" platform. One that doesn't change.
19:00 aditsu books don't have video :p
19:00 mr_lou Exactly.
19:00 mr_lou It's an eBook.
19:01 mr_lou Welcome to the future. ;-)
19:01 mr_lou Diskmag-like eBook.
19:01 mr_lou My Amstrad CPC464 is 30 years old. I still use it.
19:01 mr_lou I like the retro stuff.
19:02 mr_lou 30 years from now, there will be people using PS3 and PS4 and XB1.
19:02 mr_lou Same reason.
19:02 mr_lou Blu-ray players will be around for a loooong time.
19:02 aditsu browsing/watching your memoirs 50 years later will be like a retro-ception :p
19:02 mr_lou :-)
19:03 mr_lou Will be a history lesson by then.
19:03 mr_lou Complete with examples.
19:03 aditsu I think with the advent of streaming and digital downloads, blu-ray players will become retro sooner than you'd expect
19:04 mr_lou People have been saying that for ages. Just like they've been claiming Java was dead since its release.
19:04 mr_lou Meanwhile, the vinyl records are back.
19:04 mr_lou Experts predict a future with "room for everything".
19:04 aditsu java applets are 95% dead, java itself is a different beast though :)
19:05 mr_lou Blu-ray players aren't going anywhere.
19:09 aditsu btw, I found that game last night
19:19 mr_lou Oh? What was it called then?
19:20 aditsu Serpenti
19:20 * mr_lou googles
19:20 aditsu not much info about it
19:20 aditsu but there's a download :)
19:21 aditsu it's a fun game
19:22 mr_lou Looks nice. Very smooth movement.
19:22 mr_lou https://www.youtube.com/watch?v=NZUvGcRKziU
19:22 mr_lou Except, here you see the 50 fps on 60 hz issue. Notice the serpents are herky in their movement.
19:22 mr_lou I can't NOT see it anymore.
19:23 aditsu I don't think it ever ran at 50fps
19:23 aditsu 25 probably
19:23 aditsu the jerkiness could also be from the emulator
19:24 aditsu that video shows what happens if you start the game with default settings and don't press anything, kinda sucks
19:25 mr_lou No that's 50 fps. I can tell. It's moving 50 pixels per second.
19:25 mr_lou I know because I've seen lots of scrolltexts that move 50 pixels per second. I know what speed that is. ;-)
19:26 aditsu well, the youtube video has 30fps
19:28 mr_lou Recorded from emulator using screen recorder then.
19:28 mr_lou European computers outputted 50 hz
19:32 mr_lou The result is the same though.
19:32 mr_lou Even if a game is only 25 fps, it will still be jerky on a 60 hz display.
19:33 aditsu ok, looks like it's 50Hz interlaced, effectively 25fps
19:35 aditsu https://en.wikipedia.org/wiki/PAL
19:38 aditsu anyway, you can try to play the game (e.g. with fuse) and see if it looks better
19:40 aditsu seems like 25fps to me
19:42 mr_lou TV's PAL was interlaced yes. Retro computers weren't. They outputted 50 real frames per second.
19:42 mr_lou At least the Amstrad CPC did.
19:42 mr_lou But it had its own monitor.
19:44 aditsu can't find much about the zx spectrum refresh rate, it may be 50Hz
19:44 aditsu I also had a monitor for the HC-90, but could also connect to the tv
19:44 mr_lou It was 50 hz for all european computers because of our 50 hz powergrid.
19:45 aditsu now that I think about it, the monitor image was sharper, you may be right
19:45 aditsu oh, I think the monitor was monochrome though :p
19:46 aditsu old times
19:46 mr_lou :)
19:46 mr_lou The Amstrad CPC also had a green monitor - but also a colour one.
19:46 mr_lou Many people has a nostalgic relationship with that green one.
19:46 mr_lou I never had one of those though.
19:47 aditsu I think mine was more olive-brown, but yeah, something like that
19:47 mr_lou 50 fps may sound like much, but consider this: Moving a sprite 50 pixels per second means it'll take 6 seconds to move from the right side of the screen to the left side.
19:48 mr_lou Seems slow - but it'll be extremely smooth and nice to look at.
19:48 mr_lou Except of course if you look at it on a 60 hz screen. :-P
19:49 aditsu and the refresh rate mismatch will keep bothering you till the day you die :p
19:49 mr_lou No - because I just use Blu-ray ;-)
19:49 mr_lou Actually, I still use CRT screens.
19:50 aditsu yeah.. can a blu-ray player play old games?
19:50 mr_lou And if I have to use an LCD, then I'll use an X-RGB Framemeister to get a 50 hz screen.
19:50 mr_lou You can code emulators with BD-J. Someone already has. :-)
19:52 kirua joined ##friendlyjava
19:54 mr_lou Someone has coded a NES emulator for BD-J. And a Gameboy emulator too.
19:54 mr_lou I may look into an Amstrad CPC emulator one day, because there are already two JAva based emulators I can use.
