Apple's AAC encoders are often touted as being the 'best', quality-wise: https://hydrogenaud.io/index.php/topic,119876.0.html


I suspect the data transfer requirements of CarPlay can be handled by USB2


Exactly. If you look at YouTube bitrate for a 1080p video, it's 8mbps, which is 1.67% of the theoretical max data rate of USB2 (480mbps), so there's more than enough bandwidth for CarPlay.


Yeah USB3 and greater is really only needed for high res displays and faster large storage.


given that carplay has, until now, been exclusively implemented by devices that don't support USB3, that's a pretty good suspicion


Apple said it also will not offer "private relay" in Belarus, Colombia, Egypt, Kazakhstan, Saudi Arabia, South Africa, Turkmenistan, Uganda and the Philippines.

Can't vouch for it, but there is software available that helps with your first issue: https://mobiletrans.wondershare.com/whatsapp/transfer-whatsa...


This only works to convert WhatsApp data from iPhone to Android, but not the other way around.

I don't understand why WhatsApp won't let their iOS version access a chat backup from Google Drive.


It doesn't work if both devices are connected to different WiFi networks. But Airdrop works without being connected to any AP…


Yes, either you are both connected to the same WiFi network or both of you are not, kind of weird


My 2018 13-inch MBP is driving a 5120x2160 LG 34WK95U-W just fine, over Thunderbolt 3.


Mine too. That’s a completely different monitor and resolution. The problem is specifically with 5120x1440.


Why not use Canon's own EOS Webcam Utility?

https://www.usa.canon.com/internet/portal/us/home/about/news...


Fujifilm has also released their own native webcam utility for X and G series cameras. I think it only happened a week or two ago.

https://fujifilm-x.com/en-us/webcam-support/


When I read this I ran to get my camera and my computer!

First downer: My X-T20 is not supported :(

Second downer: Windows only?

So sad right now :(


Camera Live works with non-canon models as well, there is at least partial support for some Fuji and nikon in the alpha releases and it looks like the maintainer intends to increase support even further. The heavy lifting appears to be done in libgphoto2 which supports a ton of different models.

In terms of “why don’t you just use ____”, I have scoured the web for any way to use a Nikon as a webcam on macOS (over usb, so without dropping $120 on a camlink which is sold out everywhere now anyway), and the only other thing that exists is an app called ecamm live which costs $20/month forever. For windows and even Linux there are other more affordable or open source options.

I misplaced the usb cable that came with my nikon d5000 but I was able to find a replacement on amazon yesterday that should arrive later today.


In my experience Canon's app is way better, both on Windows and Mac


This is a recent release, eh?

I bought a elgato camlink 4K just recently because I wasn’t so happy with Camera Live but now I wish I hadn’t.


It looks like they only support newer DSLRs


Despite that list, it actually works against much older devices. I've ran it with a T2i, for example, which is like three generations older than they officially support.


Thanks -- I've been really bummed that they left 6D Mk. 1 owners out in the cold on this one.

Does anyone know of a similar linux app that works over USB rather than HDMI?


I've been using gphoto2 and ffmpeg on linux to use my 6D MkII as a webcam. I did test it with my old old rebel XSI and it did work as well

here is the command

  sudo modprobe v4l2loopback exclusive_caps=1 max_buffers=2
  gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -an -threads 0 -r 24 -f v4l2 /dev/video2
I did wrap in a shell script to test if the module is already loaded.


Works on the 6D. Thank you!

I'm only getting ~4 fps, with substantial latency. Is that your experience?

Image quality on the first lens I had at hand (40mm f/2.8) blows my Logitech 920 away. Field of view on the 920 is equivalent to a ~26mm on full-frame.

Super excited to see if my slightly-broken EOS M will do the trick, too.


Awesome -- I'll have to give it a try :)!


I've been using a 6D mk.1 with the Windows version of the Canon Webcam Utility Beta for a couple weeks now. No issues with running it, so far.


6D Mk 1 works great with Canon Webcam Utility Beta on macOS! I'm using it now.


How do you download the app? They require a serial number.



Copy/paste the link to avoid the error after clicking.


Aha, nice tip. I have a 1DX I was hoping to try it out on, has stacks of ports but I didn’t understand why it was too old. I’ll give it a shot.


That’s great because I have a T2i with magic lantern. Will have to give it a try.


Canon's app only supports Windows


They just released the Mac version of EOS Webcam Utility. https://petapixel.com/2020/05/27/canon-unveils-free-webcam-s...


There’s a beta for Mac released about a week ago


convert is part of imagemagick: https://imagemagick.org


Not on the Mac App Store



It should be disallowed. It's more anti-competitive conglomeration, and risks the contagion of corruption.


Don't expect it to blocked under our current president. Bolsonaro is basically a Bazilian Trump.


Wasn’t the a ton of whining from the US when airbus bought bombardier?


Yes, there was - but now that Airbus has small planes, Boeing's lineup "needs" to expand to match, and buying a smaller manufacturer is the easiest way to do that.
