bamse, amstan: arch question.. any idea what package(s) I need to install to get venus going?
<amstan>
robclark: as in 3d acceleration?
<robclark>
naw, 3d accel works out of the box.. that is a thing I know how to get working :-P
<amstan>
not sure offhand, it was pretty easy, do you know what's missing?
<robclark>
I mean video playback
<amstan>
oh, i don't think i ever looked at that
<amstan>
macc24: you perhaps?
<robclark>
like.. AFAIU some gst-v4l2 plugins.. or I think there is ffmpeg support
<robclark>
I'm just failing to figure out how to search arch packages ;-)
<robclark>
amstan/macc24: I don't suppose you've figured out whatever necessary UCM magic for audio on sc7180?
<amstan>
robclark: Dylanger had a saga with that a few days ago, lol
<amstan>
there was one command that manually convinced pipewire to make it go
<robclark>
heh, ok.. so that is also still TBD(ish) then?
<bamse>
didn't steev have the problems with the red-tinted playback? if so he should know what packages are needed
<robclark>
hmm
<robclark>
also, firefox on arch doesn't seem to start.. "Exiting due to channel error." ... whatever that means
<bamse>
i never got firefox to play nice with freedreno
<bamse>
it either told me that i didn't have a gpu and after telling it that i have a gpu the rendering was mostly garbage
<robclark>
huh.. it seemed to work fine last time I tried it on fedora..
<robclark>
possibly I had to do something at some point in the distant past to override ffox's gpu allowlist?
<robclark>
amstan: is this pikaur thing supposed to handle downloading dependencies and building them? (Or if not, what is the value-add over just using makepkg?)
<amstan>
yeah, it's mainly the dependencies (sometimes they can get annoying) and you not having to download anything from the aur manually before you can run makepkg
<amstan>
you also get free updates (automatically compiles the new version)
<robclark>
hmm, I cloned rmtfs-git and tried `pikaur -P` but it complains about missing qrtr.. possibly I'm holding it wrong
<amstan>
oh, yeah... that package is a little wonky, you need to install qrtr-git
<amstan>
but... hold on, if this is about rmtfs-git, it should be in the main alarm repo now (as of yesterday when i sent that message)
<amstan>
rmtfs-git doesn't point at qrtr-git directly, it points at qrtr which qrtr-git also provides
<amstan>
try just "pacman -S rmtfs-git qrtr-git"
<robclark>
what was the magic extra args to get it to resync package list?
<robclark>
ahh, -Syu
<amstan>
'y' is for resyncing, but it's a very good idea to use 'u' as well as partial upgrades aren't supported
<robclark>
do I need to do something like `systemctl enable rmtfs` ?
<robclark>
seems so.. although not seeing a wlan interface yet
<steev>
systemctl enable --now
<steev>
to also start it
<steev>
enable just enables for the next boot, doesn't start it, you need to either pass --now to start it, or systemctl start rmtfs
<steev>
the red-tinted playback for me only happens in surf
<robclark>
right.. I did `systemctl start rmtfs` first to see if it did something.. which it seems to have done
<steev>
and i never sorted out what stuff i'd need to pass to gst to get it to work properly
<steev>
you also need (afaik) tqftpserv, pd-mapper and qrtr-ns
<steev>
oh, rmtfs should start qrtr-ns
<steev>
ah, qrtr-ns should start the others, i think
<robclark>
hmm.. pacman doesn't seem to know of tqftpserv
<robclark>
yeah, I see how it is looking in the fw directory for them.. I guess CrOS does something different, but no idea what

<Dylanger>
<amstan> "robclark: Dylanger had a saga..." <- I think this change is specific to homestar/Duet 5, other Trogdor devices seem to work without it
<Dylanger>
I don't think Firefox supports the API for hw decoding via Venus yet
<robclark>
homestar did have some special stuff re audio.. like adjusting which speakers are left/right relative to tablet orientation.. no clue how that stuff worked
<Dylanger>
`mpv --hwdec=v4l2m2m_copy`
<Dylanger>
I think you can use this to do hw decoding with venus
<Dylanger>
Not sure if this API is supported on Chromium
<Dylanger>
I'm hoping it is, so I can watch YouTube like butter 🧈
<robclark>
chromium should actually have the full userspace v4l2 vid stack.. but I suspect it is all under #ifdef CrOS or something along those lines
<robclark>
I have seen video decode work in browser at linaro demo days.. but don't really remember how they got it working
