#hdmi — Public Fediverse posts

I'm looking at #HDMI stuff again #HomeLab. It's still annoying to find anything reasonably priced.

What I'd want:
* 4 inputs
* 2 outputs
* switches also USB
* Web-UI or RS232
* 8k60 (4:2:0), 4k120 (4:4:4)
* HDCP ≥ 2.2
* Price < 200 Euro
* 1 device
* low/no latency

Best I can find: PT-SW-HD41USB with 4 inputs but only 1 output for 416 Euro
+ 4 individual 1x2 splitter around 80 Euro each.
+ PT-SW-HD41MV 4x1 18G Multi-View Switcher 599 Euro (the one with also USB is cheaper for some reason?!?)

I think I may have to abandon Raspberry Pi as the platform for my little home media center project.

At this point I've tried two Raspberry Pis, swapped out the power supply for a better one, and swapped out the KVM switch for a powered one. I cannot get the PiOS to recognize the HDMI output as a viable audio output target. It can see the card, it can see it has audio hardware, but it only allows for headphone jack as an output target and I can't compel it to believe otherwise. Googling suggests I'm failing an EDID handshake, but the Chromecast attached to the same KVM navigates this issue with aplomb, so...

Feels bad solving what is clearly a software problem via hardware, but if anyone has a recommendation for a low-power Linux box that will do Wifi and proper HDMI-out-including-audio to a TV, that's really all I need.

I also learned today that the #HDMI spec makes absolutely no claims whatsoever in distance compatibility. Only in category compatibility. So anything beyond 20 feet is probably bullshit, but companies sell longer cables anyways. Caveat Emptor of course, as our infrastructure has no actual dependability, not like you'd expect. It's “give it a shot" roulette wheel game. Maybe it'll work, maybe it won’t, and the manufacturer doesn't have to actually stand behind their products either! Classy.

What a stupid run around the barn that was! At #work, with the wretched #HDMI spec, and a long cable that I can't test because either they make continuity testers for chump change or actual signal analyzers that start at $500. So to resolve long HDMI cable bullshit, I simply bought two brand new HDMI cables from #Monoprice not with the intent that they will work out of the box, but rather that they will be sacrificial cables to prove that the cable in place isn't crap. (1/2)

Spotted at lunch.

So it turns out the issue with the audio is probably not the raspberry pi. Well, not precisely.

My HDMI 4-way splitter is unpowered, and the raspberry pi is not nearly as interested in supplying it power as the other devices I have plugged in in the past are. Details still unclear on why that makes the audio refuse to connect through the wire, but it looks like upgrading my HDMI switch might actually fix things.

If you are based in Ireland and in need of a 2-port #HDMI #KVM #switch, I have one up for grabs. Potential side effect: I might accidentally serve you a cup of tea or coffee.

This is why I love #linux. I've been fighting audio issues with my church's #windows10 #zoom computer for over a month. It was mostly likely a driver / driver API breaking after a windows update. In under 1 hour, I installed #linuxmint and installed zoom and configured it to use our #focusrite Scarlett Solo and our #Guermok usb #HDMI capture stick. No more issues.

Zynq 7000. HDMI для платы Zynq Mini и Linux

Раз уж пошла такая песня, я решил добить вопрос с выводом изображения по HDMI на плате Zynq Mini. В предыдущей статье мы уже разобрали как это сделать в baremetal-сценарии, теперь пришла пора дополнить дизайн для возможности вывода системной консоли Linux, при том, что у Zynq-7000 нет своего видеоконтроллера и весь видеотракт (DMA, генератор таймингов, TDMS-кодер) должен быть построен внутри FPGA, а затем быть проброшен в Linux. Всем, кому интересна данная тема - добро пожаловать под кат!

#HDMI ist ein Arschloch

The current version of #KDE on my machine (6.7) seems to be very buggy in terms of what happens when I try to add extra monitor(s) in the #Wayland version, whether it’s via #HDMI or #USB with #Displaylink. The screens go haywire and I can even get a terminal open. I’ve had to revert back to the #X11 version just as I’d got used to Wayland. I’m no fanboy of Wayland or X11 but when such a major breaking of the system happens, it forces my hand. Not good at all.
