Okay it turns out this thing DOES have a JPEG decoder core. It wasn't in the first block diagram or feature list in the datasheet but was in another diagram much further down. So apparently it just... sucks? Also I'm realizing that I made a bit of a "video producer brain" mistake - when I'm flipping through images, I cut out all the loading after the first one because, like, I didn't want to make you all sit there for 40 seconds while I went through just a couple pictures, and I just thought "well everyone will see the cuts and realize that I've skipped some time", but looking back I realize you'd really have to be paying close attention to notice that, whoops. So yeah, each JPEG, other than that super low res one at the beginning, took over 10 seconds to appear.

It's probably the case that the bottleneck isn't the decoder, but the pathetic amount of working RAM supplied. While a compressed file may be only a few hundred kilobytes, you still need enough RAM to buffer the entire thing uncompressed otherwise it's going to end up doing a tedious amount of fetching macroblocks, decompressing them to RAM, shuffling those bytes off to the framebuffer, rinsing and repeating. My guess is there's only 4MBs of RAM, so anything much higher than 2MP is a pain to decode.

I think it's useful to understand how these products generally come about. The SOCs are cheap commodity items that cost pennies to make. Some third party then comes along and designs a board around that SOC. It might implement some or all of the chip's features, but the boards themselves are also commodity items. Someone else comes along and designs a consumer product around the board and sticks various brand names on that. So the company that made "Boifun" probably didn't make the board. And you end up with a huge variety of products with very similar features and interfaces.

That’s not a slow button scan. Buttons don’t click just once when you press them. If you look with an oscilloscope you’ll see a lot of ‘bouncing’. So denouncing is needed. You can do it in hardware, but cheaper is in software. Basically they wait for a button press, and the. Wait a fixed time to confirm the button was actually pressed. That time is what you have to exceed for the button press to register. Now, cheaper buttons bounce longer, so it’s entirely possible they had to lengthen their denounce time since otherwise it would register as multiple clicks. Great video

The problem with demonstrating the screen is that your white balance would be adjusted to your room lighting, which would be warm, but the color temp of the screen is ideally 6500K or in practice probably way bluer than that, especially if it's LED backlit, because they never calibrate them to offset the overwhelming blue.

i lucked out a couple of years ago, as a local thrift store had a DVD player monitor for sale with no plugs etc but i was able to sort out a wall wort to hook up (takes 9-12v) and has AV in besides its own proprietary input (looked to be from a kit where it had a main player and screen and then this one was to connect up for kid#2 sitting in the back seat so they could both watch Spongebob or whatever). i added mounts for a tablet wire stand and now its a production monitor that i use with a video camera i have that has SVideo out, then the cable i use converts it to Composite (its so i can frame the shot properly when i cant see the viewfinder).

I wonder if the difference in how the screen looks on camera vs. in real life is due to the display’s polarization interacting with the camera sensor. Also, no, DVDs do not actually declare their encoded aspect ratio. That feature didn’t appear until Blu-Ray. Back when DVD was specified the assumption was that everything would still be 4:3, and “anamorphic 16:9” was basically a retrofit.

The video on DVDs is actually always anamorphic so it's important for the player to know the aspect ratio of both the display and the video so it can be formatted properly.

The test ports on the board -- I think you touched on the reality earlier in the video, when someone recognized that order of ports from a bunch of these devices. Someone (organization) at some point must have designed this board with the intent of selling them to tons of product integrators like whoever made this 6-letter product. Because the board designer in turn would then need to support their customers (the people making/integrating the products), it makes sense that they would want test points designed in because they would want to reproduce and investigate any weird symptoms that the integrators run into when designing/QAing their own derivative product. That's my theory at least. Also this theory potentially unifies the silkscreened screw logos on the board that seem odd in the context of this rock-bottom product -- those input/control modules are most likely procured from a different OEM, then integrated with this product at the time of its own engineering. Again.. just a theory, but it would unify/explain why there are 2-3 different styles of PCB and component/design approach in the one product, the producers of this device were just lego-kitting it together, with most of their engineering probably being in the design of the clamshell and related engineering for assembly

boifun is quite possibly one of the best names ive seen from these things by far

The DVD spec does indeed allow for auto switching of aspect ratios, at least in Europe where it sends a signal via the scart output on pin 8 I believe. However most home DVD recorders don't seem to bother recording the aspect ratio switching signal when recording, so on playback you have to set the ratio manually as you had to. Some Pioneer and Sony models would record the aspect ratio switching signal if recording from their internal tuners but most didn't instead relying on you to manually set things up.

Regarding that MediaTek chip's CPU architecture: in certain areas, MediaTek is sort of infamous for rolling a ton of chips with different custom instruction sets tuned for the purpose (presumably generated in some sense). Considering the era and application, I wouldn't rule out that this chip runs a custom-but-uninteresting generic 32-bit RISC instruction set. Would perhaps also explain why the NES core is so slow, as it wouldn't benefit much from architecture-specific optimizations. Also, that unknown chip looks like a type II TSOP package, which gives it a high probability of being DRAM indeed. Makes sense since that's definitely not in the chip itself. Isn't there some silkscreen marking right below it that could give a clue?

I'm pretty certain that when I saw the series during its original run in the USA that "The Car" episode didn't have the glitches. If anyone has a first run off-air, cable, or satellite home recording of "The Car", that doesn't have the synch and field order glitches, I bet Tim Hunkin would be very interested in getting it, especially if it's PAL format. Even a good NTSC recording could be used by cutting the bits that are glitchy in the PAL source then doing some fancy upscaling and frames per second changing to patch over the glitchy bits.

There's a new/fourth season on Curiosity Stream.

The aspect ratio/screen type settings are totally normal (for a separate DVD player/TV setup) but rather unusual for an all-in-one device. I kinda like the flexibility though! Since it does more than just DVD playback, it does kinda need this flexibility. As for DVDs being "hard coded with the aspect ratio", yes, they are. Widescreen (true widescreen, not Letterbox) DVDs are anamorphic, and the DVD player has the ability to letterbox or crop (Pan/Scan) to fit the 16:9 video onto 4:3 screens. The Pan/Scan flag is very rarely used (aside from Legal Warnings, disclaimers, menus, etc.) Typically these are flagged P/S to give a full 4:3 image on a 4:3 screen, rather than LBX. The graphics for these are created with excess real estate at the sides (text all within central portion of screen). 99.9999 of video content is flagged to display as LBX on 4:3 screens. To save money on early DVD players, only one scaling chip was designed into the specs. Scaling of overlays (menu highlights and subtitles) is not possible in any DVD player. For menu highlights to appear correct in both 16:9 and 4:3, two separate button highlights have to be created for every menu page. Super annoying. For subtitles, 99% of DVDs share the same stream across both aspect ratios, with the result that they look a bit stretched or squashed, depending what mode you're viewing in. Japanese subtitles were typically the only language where a separate 4:3 and 16:9 stream were supplied by the subtitle vendor. The Japanese are very picky about the characters being displayed in the right shape. Other countries have to suck it up! In my experience, almost every subtitle vendor I ever dealt with (in 20-odd years of DVD authoring) was CLUELESS about the technical aspects of subtitles and had absolutely no comprehension of dedicated 16:9 and LBX subtitle streams. Only those making the Japanese subs understood how to do it 😭 Because of the way menu highlights and subtitles work, it's not possible to just batch process subtitles in Photoshop to resize them. You could, but they'd look horrible. Resizing has to be done in grayscale mode, and only after that can you remap the 255 levels of black-to-white as three pure colors (typically white background with black, red, and blue used for text body, outline, and a very crude dither). Each of these colors get re-mapped as a specific display color and opacity percentage by the DVD player.

This device is genuinely kind of amazing for all of the wrong reasons, and has a lot of self-contradictory elements. It's big for a portable DVD player, yet it has a screen to match. It has so many additional features that sound incredibly useful and desirable, especially for its price, but its hardware is too anemic and/or outdated to pull half of them off properly. It's cheap and lightweight, but it clearly has a lot of effort with its construction and even accommodates those who take it apart for repair and troubleshooting. It's too well made and functional to be considered disastrous garbage, but too crappy to be properly useful beyond its its literal product description of a portable DVD player. It's non oui personified as a piece of low end consumer electronics.

I actually one time, used a portable DVD player like this with the screen rotated 90°. My family was on a roadtrip kinda holiday, but being a weird nerd, I brought a PSOne. Because of parents using the main tv, I had to hook into one of these in the bedroom. Because there was no desks, I put it on the bedside table, rotated the screen towards the bed, and played like that.

Letterbox and aspect ratio settings of this boi are absurd. I seriously doubt anyone ever watched a movie in proper fullscreen with correct aspect on this thing.

The software in that player is also just like what would be in a digital picture frame.... Similar menus and such too.... I think the reason why the pictures are so slow to load is because it was expecting to be more of a slideshow or flipping through images.... And the battery life also designed to be used in a picture frame item... Most of those could play videos just fine if you loaded a few on there. 😊

I have an old 2010 RCA DVD player that I'm pretty sure uses basically the same software, just without the USB or NES stuff in it, and I think it's also missing that on screen settings menu. Not sure what files it will play off of DVD, but I know when playing an audio CD it showed almost the same menu as the file browser in the boifun player. When playing DVDs the on screen symbols were also the same, I'm tempted to take mine apart and see what chip it has, and maybe make a DVD with a bunch of files to test with.

Re: The VDU suffix on the main chip - perhaps it means it supports a display (i.e VDU) output via LVDS which isn't required in other applications.

Man, your videos are really high on my list of "immediate watch" content and I love to avoid reading the title, because I know it's going to be a fun ride and usually on the longer side of things.... I need more! 😁 Your humor usually has me laughing at the most random stuff and that's never a bad thing! Fantastic video as always. Have a wonderful day! 😊🌎❤️🕺🏻🐶💻

Seriously, he made an interesting and informative video about a portable DVD player, which I've always viewed exactly as he does.

As soon as I saw the Game logo, I knew it would play NES games. Given the awful performance, I actually expected it to be a Famiclone with a DVD player bolted on. But, the games also running terribly disproves that. The games were cut off the same way as the text. Probably an aspect ratio issue? Having once used a PlayStation homebrew app to read a text file off a disc to help repair my PC, I agree that text viewers should be included in everything.

12:10 TRRS cables, as an idea, should be really helpful… but because of a lack of standardization, we end up with irritating things like this. I was just dealing with something like this myself when building a crossover cable that lets me interface my sound card with my phone to send/receive data with minimodem.

They actually ARE pretty standard. There are variants, because each is optimized for something different. Is it an audio device with video capability? Then you want tip and ring to be L & R audio, with the third signal, video, being something that you need a special cable to access. This ensures backward compatibility with audio cables and headphones. If you’re making a camcorder, then you can live without stereo audio, as long as you get one audio channel and video. That puts R audio on the optional conductor. “But why the difference between shield and the additional ring?” Well, that depends on the jacks that cable will be used with. Many jacks use a shield contact that is higher up on the plug. Those? You need the second ring to be ground. Other jacks contact the shield at the base of the plug. For those, you want shield to be ground. None of that matters when you’re just using TRS, so decades of COTS jacks never had to care. But with TRRS, it does. See? There’s a reason for all the madness, as long as the manufacturer chose the most applicable wiring for their specific device’s primary function and the ecosystem of things that are usually going to plug into it.

Likewise!

I think the text reader is probably working correctly but expecting 16-bit character sets to draw chinese charcaters in a different orientation (say, vertical instead of left to right horizontal). It probably gets to the end of the first line, encounters a line-feed or carriage return and proceeds to flip it's shit for the remainder of the file.

This was fascinating, for some reason... looking forward to the next one!

8:25 If the processor was scanning the buttons that slowly I would expect it to work ~sometimes~ if you pressed it fast. Or if it's multiplexed, to actually activate a different button. I think it's probably just overly-aggressive de-bounce. 22:45 That text editor makes me think you could get it running arbitrary code with a poisoned text file haha. Shame the screen is so shiny. Would otherwise have been nice for a homebrew laptop.

Nice work. I started watching your videos a long time ago.. it’s been great to watch you climb the mountain of KZread content. I have always enjoyed your videos but have to say they are even better since you made this ysour full time gig. I currently work in IT, stagnant wages and stagnant opportunities. You got out just in time my friend. Keep making these well researched videos, you certainly have a gift for it. ✌️

the VDU suffix probably stands for video display unit, perhaps refering to a tv with a built in dvd player.

Oh my god! I used to have a DVD player with a 'game' port and it came with a cheap usb controller (I did try it on my PC at the time, didn't work at all) and it came with a little mini dvd that had some terrible games on it. It even had an analogue TV tuner that I used on a car journey to watch CBBC (I live in the UK, this was a few years ago). It had the exact same UI as this player as well, except it had the analogue TV tuner as another option

This was great! You always make great videos, man.

Love the smol D420! Have one as well

Lots of fun to be had here, but it's the NES that got me saying "Gravis, no!" out loud. I enjoyed the video, no worries about the editing. Hope your new BOIFUN proves useful in future productions!

You did great! More of these videos! Love it!

VWestlife recently published a video about the unstandardized hell that are TRRS jacks. As for the 90 degree flat screen, the instant you did that I thought of putting it in the pocket of the seat in front of you on a plan or some such (obviously using headphones!)

the main issue as to why cameras don't capture some monitors correctly is because the RGB output of a lot of screens are sharp peaks, that your eyes aren't bothered by, but cameras can't really capture the color correctly. similar to how certain things appear to have different colors under incandecent vs flourecent lighting.

I would suspect that the main PCB and the two button PCB's are part of an off the shelf type kit. They are heavily labelled to let you know where to attach your own cables. You can build it into any shape and size product you like. The screw holes are probably silk screened to show you that you can put a screw there without shorting traces to ground.

I love these silly videos where you pick something up and it’s suddenly more interesting than you could ever account for.

Apparently you can get the firmware version & de-zone MT1389 devices. FW: - Push "Home Menu" on the remote - Go to "Initial Settings" - Highlight "Options" (Do not enter) - Push "Display" on the remote Zone: - Push "Setup" - Enter "1379"

The AV input back in the day was awesome. I had a Panasonic portable DVD player back in the early to mid 2000s, when you wanted to play games on a road trip, this was awesome. The problem was, the only TVs that most people could both afford, and afford one just for travel was a CRT. No one was trying to put a Plasma or LCD in their car or van. Not to mention, you'd still need an inverter to take 12V to 120V, and the ones you could buy easily were rather small and wouldn't power either of those. Sure you could get 12V CRT displays, conversion vans used them a lot, so did a lot of campers of the era but they were still big and heavy and really weren't great options. However, these things solved all those problems. You bought a portable DVD player that had a 12V adapter, you bought a cheap 60W inverter. And you could now play games anywhere you had 12V. I played a lot of GameCube games on the road using a setup like this. You plugged the game cube into the inverter, and the DVD player ran off its internal battery for a couple hours, it was actually pretty good battery life without the DVD player running. The only other thing you needed was an RCA female-female adapter so you could plug the two cords together. Thinking back, this was actually a pretty similar layout to those devices, just in a larger package. It was awesome.

i really didnt expect so much lore this is crazy

The pinout for the usb port is likely similar to the ones you get on modern famiclones which have USB controllers; that is: 5v, gnd, clock, latch, data, with some pinout which uses the shield as it's own conductor. If you look at what's near that game port on the PCB then you could probably solder on a real nes controller and have that work.

Very nice video, really enjoyed going down the rabbit hole of a cheap weird branded device, always wondered what was in them and how it was all done through the hardwere and softwere. I also really like the modern Mediatek CPUs in the phones, they have gone a long way from what they used to do in the past.
