2·6 months agoA while back, I tried looking into what it would take to modify Android to disable Bluetooth microphones for wireless headsets, allowing for call audio to be streamed via regular AAC or aptX, and for the call microphone to be captured from the phones internal mic. This would prevent the bit rate for call audio in microphone being effectively halved when using the ancient HFP/HSP Bluetooth codecs, instead allowing for the same call quality as when using a wired headset. This would help when multitasking with different audio sources, such as listening to music while hanging out on discord, without the music being distorted from the lower bit rate of HFP/HSP. This would also benefit regular VoLTE, as the regular call audio quality already exceeds that of legacy Bluetooth headset profiles.
Although, I didn’t manage to tease apart the mechanics of the audio policy configuration files used by the source Android project, given the sparse documentation and vague commit history.

I’d certainly be fine with the awkwardness of holding up and speaking to my phone as if it was in speaker mode, but listening to the call over wireless headphones, in order to improve or double the audio quality. Always wondered what these audio policies fall back to when a Bluetooth device doesn’t have a headset profile, but it’s almost impossible to find high quality consumer grade Bluetooth headphones without a microphone nowadays.
For the call setting under Bluetooth audio devices, I really wish they would break out or separate the settings for using the audio device as a source or sink for call audio. Sort of like how you can disable HSP/HSF Bluetooth profiles for audio devices in Linux or Windows.

For anybody wondering what the Mastodon security issue is - CVE-2023-36460, you can send a toot which makes a webshell on instances that process said toot. #CVE202336460 #TootRoot
Looks like they posted the video process timelapse of that artwork here:
I’ll have to checkout their webcomic Pepper&Carrot. Thanks for the reference!
1·1 year agoThat looks neet. Although I suspect this would succumb to the same cross post discoverability issues where URLs pointing to the same video would not match string for string. A better approach might be to facilitate inline embedding of HTML video players into Lemmy using browser extensions, where user scripts could be used to preview youtube links or re-write them to nocookie, allowing the Lemmy web UI to still avoid the use of cross-origin scripts by default.
Found the full transcription for the video from OP author:
Note to self: use
youtube.cominstead ofyoutu.be
for better cross post detection and lemmy integration
For programming tutorials, yep, I also prefer reading documentation instead. Although, it looks like this tutorial these folks put out doesn’t have much of anything you could copy from, like terminal commands, given its a recorded walkthrough in using the graphical web UI. YouTube also now allows for searching the auto or manual transcription text, which is handy when creators always forget to include timestamped chapters.
Checking the issues tracker for RES, there’s not yet any mention of lemmy or kbin:
Perhaps you could ask there. I’d also recommend checking out the Lemmy Plugins & Userscripts community:
For posterity, I later stumbled upon the authors original post here:

The community that this was posted from also looks interesting:

Do you have any links or references to learn more? Perhaps any github tickets to follow? By bootstrap, are you referring to this?
I’m using a recent 42" LG OLED TV as a large affordable PC monitor in order to support 4K@120Hz+HDR@10bit, which is great for gaming or content creation that can appreciate the screen real estate. Anything in the proper PC Monitor market similarly sized or even slightly smaller costs way more per screen area and feature parity.
Unfortunately such TVs rarely include anything other than HDMI for digital video input, regardless of the growing trend connecting gaming PCs in the living room, like with fiber optic HDMI cables. I actually went with a GPU with more than one HDMI output so I could display to both TVs in the house simultaneously.
Also, having an API as well as a remote to control my monitor is kind of nice. Enough folks are using LG TVs as monitors for this midsize range that there even open source projects to entirely mimic conventional display behaviors:
I also kind of like using the TV as simple KVMs with less cables. For example with audio, I can independently control volume and mux output to either speakers or multiple Bluetooth devices from the TV, without having fiddle around with repairing Bluetooth peripherals to each PC or gaming console. That’s particularly nice when swapping from playing games on the PC to watching movies on a Chromecast with a friend over two pairs of headphones, while still keeping the house quite for the family. That kind of KVM functionality and connectivity is still kind of a premium feature for modest priced PC monitors. Of course others find their own use cases for hacking the TV remote APIs:
