jfredCan someone with a Reform run `upower -e` and show me what the output should look like? I'm still waiting on a fuse to replace F2 but I don't see an AC adapter device in mine which I would at least expect to see on other laptops01:53

jfredAh, reading through scrollback and I just saw minute's comment about power flowing around F2 through the battery monitor chip. And I see mb2.5 swaps the 100 ohm R9 for a 10k ohm one. It's been way too long since I've done much electronics but I'm curious to understand what was happening... R9 is in between BAT1FUSED and pin C8 of the LTC6803, which appears to be one of the inputs for monitoring cell voltages. What effect does that have?03:51
jfredAlso trying to work out how Q17 could have failed (they didn't tell me how exactly but I think MOSFETs often fail short?) and if that might have damaged something elsewhere03:57
jfredMy ultimate goal of course is to 1) make sure that when I replace this fuse nothing else breaks and 2) try to avoid this happening again... but also would be nice to have a better understanding of how it all works 😅03:58

chartreuseSounds like almost the same failure I had. My Q17 did fail again after replacing right away but that could have possbily been a bit of foil I missed or something, took out D5 with it as well the second time04:18
chartreuseCould have also been from power it up without the batteries that second time, dunno04:19

vkoskivminute: Is the guide for building ffmpeg/mpv with hw decoding still relevant? Thinking of trying it out.15:45

joschvkoskiv: what OS are you running on the reform?15:49
vkoskivv315:49
joschvkoskiv: in that case, your ffmpeg is already patched15:49
joschvkoskiv: and you can get clapper via "apt install clapper"15:49
vkoskivHm. I haven't observed hardware decoding in the interrupts file15:50
vkoskivMaybe it doesn't work if I'm using mpv when watching a youtube video?15:50
vkoskivI need to get a video file and test.15:50
joschvkoskiv: afaik the patches are for h264 hardware decoding and youtube will often serve you content in vp9/webm15:52
gsorayoutube will serve up to 720p in mp4 iirc15:53
vkoskivAh. I just downloaded a webp video. mpv played it with software decoding, and clapper failed to play it at all. "Not enough memory to allocate sink buffers"15:54
sknebelyoutube-dl (which I think mpv also uses in the backend when given a YT-url directly?) can be told to prefer specific formats too15:55
vkoskivI specified 720p for mpv and it's still downloading a vp9 video, it seems.15:55
sknebelhttps://github.com/ytdl-org/youtube-dl#format-selection15:56
vkoskivThanks, I'll try downloading mp415:57
vkoskivI have an mp4 video playing in mpv now, and I don't see the hw decode interrupts going up.15:58
vkoskivI do see the second one has 4 interrupts on cpu015:58
vkoskivHey! Clapper plays this mp4 video, and now I see it using hw decode15:59
vkoskivVery cool, it's using only 25% CPU too while playing16:00
vkoskivI'll try to find out if I can use clapper to play youtube videos directly with streaming16:00

vkoskivjosch: rafostar/gtuber? Doesn't seem like there is a package of it16:22
joschoh dear you are right!16:23
joschvkoskiv: would you like me to send you some *.deb packages?16:23
vkoskivIf you have some handy, that would be great16:24
vkoskivI can also try compiling it16:24
joschvkoskiv: in case you want to compile it yourself, the Debian sources are here: https://salsa.debian.org/gnome-team/gtuber16:24
vkoskivNot 100% sure what gtuber *does*16:25
joschvkoskiv: it's what youtube-dl is but for gstreamer16:25
vkoskiv"C library to fetch media info from websites" is far from verboser :D16:25
joschvkoskiv: so if gstreamer is opening a https url, then the gstreamer gtuber plugin knows how to download and stream that16:25
vkoskivI don't know if I'm using gstreamer. Is that a clapper thing?16:25
joschvkoskiv: yes, clapper is a gstreamer frontend16:26
vkoskivCool. Then it's useful, clapper seems nice.16:26
joschi've been using it for nearly a year now because it can do hardware decoding out of the box16:26
vkoskivYeah, so far I've been happy enough with software decode in mpv, as it worked good enough16:27
vkoskivBut a more lightweight decoding is very nice to have.16:27
joschvkoskiv: https://mister-muffin.de/reform/gtuber/16:28
joschvkoskiv: the .changes file is signed with my GPG key so that you can make sure that this is not rooting your system :)16:29
vkoskivSo do I install these deb files one by one or is there a trick I don't know about?16:29
joschthere is not really a trick16:31
joschwget them and then apt install ./foo.deb16:31
joschi should upload them to experimental then it'll be easier to get them16:31
vkoskivIs that missing a file? I see it installed some libraries, but no gtuber binary16:38
vkoskivOh, I guess it just makes it so `clapper <youtube url>` works16:43
vkoskivI still get an error that the video is unavailable, but it's trying16:43
vkoskivThe error is coming from "gestgtubersrc.c" so I have to assume clapper picked up the library I just installed16:48

Boostisbetter'Really looking forward to being able to replace the Penkesu with the Pocket Reform. Although the Penkesu is pretty compelling for how affordable it is and easy to repair. 19:19
BoostisbetterI am equally impressed, however, with how capable the pi zero 2 w is. I mean I am using the 32 bit version of Pi OS on it because of the amount of RAM with the zero, but I have a Radxa Zero with 4gb of RAM and an Ampripper that I want to test. It would be a significant upgrade to the Penkesu. 19:24

minuteyeah it is bizarre19:58
jfredminute: Will you be selling the version 2.5 motherboard separately at some point? Using the old motherboard in that 1U case you're working on could be nice as you might not even need batteries there and could mostly avoid that part of the board (though dunno if you were thinking of setting aside space for them as a UPS)20:01
joschwhat surprises me most about what i've read about A311D from minute is not so much its performance (because it appears i'm very happy with the compute power of the imx8mq) but the power to watt ratio -- that sounds so cool! i'm very hyped about more SoMs for the reform with similar characteristics :)20:05
