The right way to play a piece of music in a #Teams town hall is obviously with #ffmpeg with lyrics as subtitles and scopes for visualisation, trough a #decklink into #atem mixer. Obviously.
Right? 🤓

Decklink output to SDL.. would be interesting.
#sdl #decklink #blackmagicdesign

A bit fiddly, library handling on windows is "funny", but my little #Qt #decklink test app now runs. If only I had any thunderbolt #decklink devices to actually test with on this laptop.

#Decklink SDK is a bit of a #pita to use when code should run on both #linux and #windows, especially when you aren't used to any Windows specific stuff like COM, midl, BSTR and whatnot. argh

Basic audio output works from #qt mediaplayer. Next to figure out how to prebuffer so it won't glitch. #decklink

Video frames are captured successfully and displayed in #qtquick VideoOutput. Next is to somehow handle audio frames. And obviously a #Kebu video as test stream.
#decklink #blackmagicdesign

Sigh, seems even if driver says rgb capture is supported it does not mean shit. #decklink

Seems you can grab directly to rgb but only in some specific fps and resolutions. Code changes done, testing tomorrow. #decklink #blackmagicdesign #qtdev

Funny, for some reason #key feed level started to default 0 this week. Last week it was 255. What the actual fuck? Not that I've spent hours debugging why it suddenly stopped working.. #ffs #decklink #BlackmagicDesign

It was working last week. Now what? #ffs #decklink

And we have input frames :) #decklink #qt #qtdev #qtquick

Ah, vague documentation is oh so fun to work with. #decklink

Input seems to be a bit more involved and obviously there is no format conversion, requested grab format must match exactly with incoming frame format. Sigh...
#decklink

It's starting to get usable, a #qtquick friendly #decklink sink. #qt

So yeah, started scratching a little #ffmpeg #decklink itch. No support for RGBA playback, so no keying, go figure.
#BlackmagicDesign

Trying to wrap my head around the #decklink sdk api changes and how to adjust #ffmpeg

I just might scratch that itch myself... How hard can it be? #ffmpeg #decklink #api

#ffmpeg visualization of a mod via #decklink output to video mixer. Serious geekery 🤓
#blackmagic

Annoying when the vendor software basically stinks, looking at you #BlackmagicDesign Media Express.
#decklink

But that is luckily not a problem as it is easy to build yourself, already got one with #decklink and #whisper ready to go 😍

While searching for a #windows #ffmpeg with #decklink support I learned about #winget
I did not know about that.

More #decklink to play with.

Anyone know any good sources for used AV stuff? I'd like to experiment with a #decklink #sdi output card but can't really justify the price of a new one for a personal project. #ebay is just ridiculous. #mpb does not seem to get any PCIe stuff. #google just sucks. #blackmagic #audiovideo

And we have image display. #decklink #qtdev #qtquick

Anyone a bit more clued-up about video signals than I am, can you help solve this one?
I have my retro computers connected to my Decklink card via my OSSC. The Decklink seems okay with other systems (N64 and PS1 both tested) but all I get from my computers is this sort of thing. Very flickery and obviously not suitable for use otherwise!

More details in thread.
