| tannewt | mithro, I'll have more (maybe too much) time starting tomorrow evening after my fiancee leaves for a vacation. So night I probably won't have time | 01:36 |

| CarlFK[m] | Kamilion mithro Do you have a ThinkPad power supply I can borrow/ have? Round plug | 04:27 |
| mithro | CarlFK[m]: Round plug might be hard, could check when I get home | 04:27 |
| Kamilion | uh, only one I see around is the D plug | 04:27 |
| CarlFK[m] | Kamilion have any i7 laptops for sale? | 04:28 |
| Kamilion | yes | 04:29 |
| Kamilion | that's a very vague question though, lol | 04:29 |
| Kamilion | considering there's eight generations of i7 | 04:31 |
| Kamilion | i7 first showed up in 2008 ;) | 04:32 |
| CarlFK[m] | Iv been thinking I need a newer laptop. Mine has some crackers in the case and the keyboard is starting to fall, again | 04:32 |
| Kamilion | buy a clevo, lol | 04:32 |
| CarlFK[m] | Cracks. Maybe crackers too | 04:33 |
| CarlFK[m] | Wats a clevo? | 04:33 |
| Kamilion | one of three major laptop manufacturers you've never heard of but has built a sizable number of the laptops other than apple that you've seen out there. | 04:33 |
| Kamilion | the others are Compal and Quanta. | 04:34 |
| Kamilion | the three big laptop ODMs | 04:34 |

| Kamilion | https://www.xoticpc.com/sager-np6853-clevo-n850ek1.html | 04:36 |
| Kamilion | don't mind all the gaming babble | 04:36 |
| Kamilion | you want *any* entry level geforce card for video editing with adobe though | 04:37 |
| Kamilion | which means you're already looking at a ~$800+ laptop | 04:37 |
| Kamilion | the clevos at least have the advantage of ease of long term maintinence | 04:38 |
| Kamilion | sager and many others brand them as their own models | 04:38 |
| CarlFK[m] | I don't do adobe. The ThinkPad had Intel graphics I think | 04:40 |
| Kamilion | eh, if you're not using mercury, there's no real point in having GPU accleration at all; it's easier to take advantage of intel's Quicksync accleration in the processor. | 04:41 |
| Kamilion | https://www.xoticpc.com/sager-np3132-clevo-n130wu.html | 04:41 |
| Kamilion | lotta people complain about the keyboard on that one though | 04:42 |
| Kamilion | it's funny, I hear a lot of people complaining laptops are getting too small and thin now | 04:43 |
| Kamilion | outside of the aluminium macs, the plastic crap from everyone else like toshiba breaks with ease | 04:43 |
| Kamilion | if I wasn't doing accelerated video editing, I'd probably just be using one of the cheap $95-120 intel tablets. | 04:44 |
| CarlFK[m] | I want a keyboard | 04:47 |
| Kamilion | okay, that costs a LITTLE more | 04:47 |
| CarlFK[m] | And I do video encoding on it. | 04:48 |
| Kamilion | https://www.amazon.com/AWOW-64-Touchscreen-Detachable-SimpleBook-GB-4/dp/B07DSPXNMZ/ | 04:48 |
| Kamilion | this will probably already kick the shit out of your thinkpad, except for libreboot compat | 04:49 |
| Kamilion | there's others, search for "Z8350 64GB" | 04:49 |
| Kamilion | more than $280 is too expensive. | 04:50 |
| Kamilion | https://www.amazon.com/HP-10-p018wm-Detachable-x5-Z8350-Processor/dp/B078SC3RV1/ | 04:50 |
| Kamilion | example, here's a name brand with the same setup, but much uglier | 04:50 |
| Kamilion | anyway | 04:52 |
| Kamilion | what I was TRYING to say though | 04:52 |
| Kamilion | https://www.amazon.com/NuVision-Touchscreen-x5-Z8300-Quad-Core-Processor/dp/B01MYZEPGP/ | 04:52 |
| Kamilion | This is very similar to that more expensive z8350, but a little slower on the CPU side. | 04:52 |
| Kamilion | Here's the thing though | 04:53 |
| CarlFK[m] | Don't care about libre boot core. | 04:53 |
| Kamilion | at $95 each, BUY F--KING FOUR, and do four encodes at once. | 04:53 |
| Kamilion | you get sixteen cores for $400 | 04:53 |
| CarlFK[m] | Lol | 04:53 |
| Kamilion | and each one's a full hd screen you can use for other stuff or just turn the screen off and let it continue encoding | 04:54 |
| Kamilion | they have batteries, ETC ETC | 04:54 |
| Kamilion | they have decent 802.11N 450mbit wifi | 04:54 |
| CarlFK[m] | Wow. | 04:55 |
| Kamilion | I showed you that little hdmi capture dongle right? | 04:55 |
| CarlFK[m] | Yes | 04:55 |
| Kamilion | it's what I plug into my tablet, which I then plug into the canon D3400 | 04:56 |
| Kamilion | cheap ass clone of the magewell adapter | 04:57 |
| Kamilion | pretty much HDMI to TDMS to UVC Webcam. | 04:57 |
| cr1901_modern | mithro: Pretty sure I figured out why icebreaker riscv is crashing | 04:58 |
| Kamilion | only, the one I picked up has inappropriate HDCP keys! :D | 04:58 |
| cr1901_modern | I forgot to do something important in the startup code- copy .data section to RAM | 04:58 |
| Kamilion | as long as I use amcap or vlc to open the capture device, I don't get any lag. | 05:00 |
| Kamilion | the rediculous thing? | 05:00 |
| Kamilion | whatever hdmi chip they used in it is a full on television system on chip. you get a bouncing "No signal", and overlays of "HDMI1 1920x1080" like a cheap flat panel TV | 05:01 |
| Kamilion | it's no wonder that it has no problem with hdcp content | 05:01 |
| Kamilion | "yk752", branded as a 4K capture dongle... it will display a picture if fed with 4K signal, but can only *record* at a scaled 1080p. | 05:02 |
| Kamilion | *shrug* | 05:02 |
| CarlFK[m] | Inappropriate? | 05:02 |
| Kamilion | yeah. Technically it shouldn't be allowing capture of HDCP content. | 05:03 |
| CarlFK[m] | Heh | 05:03 |
| Kamilion | but as far as it's concerned it's a television-on-chip connected to a UVC webcam chip | 05:03 |
| Kamilion | with the LCD panel output fed to the webcam chip's input | 05:03 |
| Kamilion | the nice thing? Captures weird resolutions too. Just scales them to 1920x1080. | 05:04 |
| Kamilion | 720x400 early BIOS startup screen? No problem. | 05:04 |
| Kamilion | in fact, it's actually kind of annoying because it makes it impossible to get pixel perfect screenshots. | 05:05 |
| Kamilion | https://puu.sh/C4gET/0d022564e5.png | 05:05 |
| Kamilion | but it sure is a clean capture! | 05:06 |
| Kamilion | no speckle or jitter between the television chip and the webcam chip. | 05:07 |
| Kamilion | hard to find 'em now | 05:07 |
| Kamilion | they were on amazon for like, four months, and then people caught on that you could record PS4's HDCP output and it got yanked | 05:07 |
| Kamilion | still, $57 was and still is an unbeatable price point | 05:08 |
| Kamilion | even if it IS lying about being 4K | 05:08 |
| CarlFK[m] | 57 is nice | 05:18 |

| tpb | Title: Lets Take A Look At Both The YK930 and YK940 (at www.amazon.com) | 05:47 |
| Kamilion | i watched reviews on them all on youtube before buying two of the YK752s | 05:52 |
| Kamilion | mainly because it was the physically smallest unit of them all | 05:52 |
| Kamilion | and I didn't wanna lug around anything big with my tablet | 05:53 |
| Kamilion | I've got one of the nice thin monoprice redmere HDMI cables | 05:53 |
| Kamilion | so it's no more obtrusive than a USB charger cord hanging off the tablet, pretty much | 05:53 |
| Kamilion | and having the HDMI passthrough makes no sense for me; as the whole point of me having it was to use the tablet as a spare screen | 05:54 |
| Kamilion | also, beware the hdmi passthrough unit -- it doesn't break HDCP, and you have to have a monitor plugged into the passthrough or it doesn't get an EDID | 05:54 |
| Kamilion | they're still bouncing around ebay though | 05:56 |
| Kamilion | https://www.ebay.com/itm/YK752-USB-3-0-FHD-Drive-free-1080P-60FPS-Video-Capture-Box-OBS-VLC-Live-Streamin/153259090025 | 05:56 |
| Kamilion | price has gone up or I got it on sale for $57 | 05:56 |
| Kamilion | not a bad deal for adding HDMI input to a 8" windows tablet. | 05:56 |
| futarisIRCcloud | Yep. ~70 USD / 100 AUD seems ok price for the YK752 ... Monoprice redmere goes up to 100ft. | 05:57 |
| Kamilion | won't last long though, the word is already out that it bypasses HDCP | 05:57 |
| Kamilion | so get while the gettin's good | 05:58 |
| Kamilion | spits out a nice 35mbit stream dump, plenty of data to have xvid or x264 throw away during psychovisual encoding | 06:00 |
| Kamilion | and get down to the nominal 7-10mbit youtube 1080p bitrate | 06:00 |
| mithro | https://usercontent.irccloud-cdn.com/file/OtKCPhil/image.png | 06:01 |

| Kamilion | but it's got "Live streaming" branded on the plastic; and it pretty much only lives up to being a decent OBS source for a playstation four or xbox one | 06:01 |
| Kamilion | I did try plugging it into my phone, downloading their software, and capturing output that way too. Worked alright. Spits out 1080p h264 files, nothing special | 06:02 |
| Kamilion | least the android software was in english. | 06:03 |
| futarisIRCcloud | mithro: Looks good. | 06:06 |
| mithro | futarisIRCcloud: Is the USB requests line wrong? The first two transfers were naked.... | 06:07 |
| futarisIRCcloud | mithro: NAKed? Not sure why the first two were. Maybe CRC16 wasn't correct because of some reason? | 06:11 |

| xobs | Huzzah! | 06:57 |
| xobs | Managed to get the board to boot, load a bitstream, flash some LEDs, and the clock even works with the dead-bug 48 MHz crystal. | 06:58 |
| mithro | xobs: lol :-P | 06:58 |
| xobs | Hooray for FPGAs. If one pin doesn't work, just use a different one. | 06:59 |
| *** rohitksingh_work has quit IRC | 07:00 | |
| mithro | xobs: yeah :-P | 07:00 |
| xobs | Also, the icestorm stuff is fantastic. Just shout the .bin file over SPI and the ICE40 gets programmed. | 07:01 |
| futarisIRCcloud | xobs: "just use a different one" - sometimes it doesn't matter if someone routed the PCB incorrectly. | 07:04 |
| xobs | futarisIRCcloud: yeah, I'm super lucky that I routed the only other gbuf line to a pin that's easy to hit. | 07:05 |
| xobs | And SPI flash booting works! I just need to work around a Raspberry Pi SPI issue where it doesn't honor the cs_change flag, and resets SPI_CS after every transaction. Solution: do it all in one transaction. Today has been a good day. | 07:56 |
| xobs | Now the only big question mark is USB. | 07:56 |
| *** rohitksingh has joined #timvideos | 08:19 | |
| mithro | xobs: What I'm not sure I understand about USB is when it is valid to change the EP you are requesting? | 08:36 |
| xobs | mithro: At any time. It's part of the SETUP, IN, or OUT packet. | 09:08 |
| xobs | Packets always come in threes. The first is a SETUP/IN/OUT, which includes the EP number. The next is a DATA, which comes either from the host (SETUP or OUT), or from the device (IN). Then comes an ACK/NAK. So you can get a different EP any time you get a new SETUP/IN/OUT packet. | 09:09 |
