tuxd3vdoes any one know the purpose of those 4 holes in RaspberryPi zero w, close to 40 pin header GPIO??02:08
c0rneliustuxd3v: I believe its for uart03:30
tuxd3vc0rnelius, thanks, I tought it could be for ethernet, some pins availlable to connect a rj45 socket..03:32
tuxd3vhold on tight guys07:01
tuxd3vc0rnelius, do you use this project to get video streamer over network?20:09
tuxd3vhttps://github.com/jacksonliam/mjpg-streamer20:09
tuxd3v?20:09
tuxd3vI read that it uses some power, the encoding is not hadrware made but software made instead..20:09
tuxd3vI got a cam500B in the mail :)20:10
tuxd3vto test nanopi neo Air camera..20:10
tuxd3vffmpeg is another option for what I read, but probably I need to compile it with some special option or even patches..I don't know yet..20:12
tuxd3vhttps://paste.debian.net/hidden/44e6e65c/20:17
c0rneliustuxd3v: Nope. I use Samba/Minidlna on my NAS and normally Kodi for streaming.21:58
c0rneliusBut for streaming in general with MPV or VLC also works fine.21:59
tuxd3vI was trying to find some software that do hardware encoding to free the cpu of that process.. but seems that in mainline there are not yet support for encoding aceleration :/22:05
tuxd3vjust discovered that..22:06
tuxd3vI don't know the amount of resources it will take for video encoding.. guess that only experimenteing and see by myself what it turns out to do..22:06
tuxd3vfor what I understood linux-sunxi is still doing reverse-engineering of the closed source blobs :(22:08
tuxd3vso it won't come in the near future to mainline..22:08
tuxd3vho.. and there are only 1 person around it..22:09
c0rneliusBootlin worked on the sunxi stuff. It works, but the boards heat up pretty bad.22:28
c0rneliusAllwinner is not a good choice in general for what ur looking at.22:30
zmomentHi, I'd like to run a qemu image of devuan for arm8 (aarch64).  Is there any generic image for this system?23:42
gnarfacehttp://arm-files.devuan.org/23:44
gnarfacethere's some arm builds here for various things23:44
gnarfacethere's more untested ones hidden elsewhere that is linked from an old forum post23:45
stiltrI base my images of these: https://jenkins.linuxcontainers.org/view/Images/job/image-devuan/architecture=arm64,release=beowulf,variant=default/23:45
stiltrs/of/off/23:45
gnarfaceafaik there's no "generic" one... every one of them has one or more specific hardware models in mind, and carries vendor-specific stuff to enable it23:45
zmomentI only tried the rpi4 one but couldn't boot and read else where that qemu doesn't boot rpi images...23:46
gnarfacea whole qemu instance is kinda overkill - if you're just making a build environment you can do it with chroot and debootstrap23:46
gnarfacethe built-in multiarch features will work for amd64 <-> arm64 if you do a couple extra steps23:47
gnarfacejust fyi23:47
stiltrI just use qemu-arm-static and chroot into the image for most of my stuff.23:47
zmomentit's not for development, it's to run a software.  My hope was to run aarch64 qemu on aarch64 rpi4 system.23:47
gnarfaceyea, that worked for me after gcc 7.823:48
gnarfacebefore that it was all broken unless you introduce 3rd party compilers23:48
stiltrAh, makes sense. I don't think I tried it before then.23:48
gnarfacehmmm, i don't know what is up with the rpi firmware and qemu, haven't tried it, first i've heard of it23:48
stiltrMaybe you could use something like lxd?23:49
zmomentit's a good suggestion.  I'll try and find the best solution.  Thanks23:50
stiltrSure! Are you just trying to keep things separated or is there another reason not to run it "natively"?23:54
gnarfaceyea, linux-vservers should be a pretty nice light containerization approach too but i don't see any approaches that don't involve building a custom kernel23:55
gnarfacenone of this hardware is that well standardized yet23:55
gnarfacemaybe someone has a fix based on the rpi firmware already floating around and it's just not well publicized?23:55
stiltrWhat's the issue with the pi fw?23:56
zmomentI got the info from https://blog.agchapman.com/using-qemu-to-emulate-a-raspberry-pi/  (kernel section) which leads to  https://github.com/dhruvvyas90/qemu-rpi-kernel23:59
