aw, we apparently missed more honest capture device

https://www.amazon.com/gp/aw/d/B08MPPKZ55/ref=cm_cr_srp_mb_bdcrb_top?ie=UTF8 ‎4KVC00 from "V AV access" in reviews ==== A true YUY2, USB 3.0 capture card capable of 1080p 60fps! Reviewed in the United States on June 7, 2021 For the price, this thing is awesome. It's actually USB 3.0 (instead of just a fake blue connector) and is capable of delivering raw 1080p60 video for capture! I've been looking around for a good 1080p60 capture card for my Nintendo Switch, and this fits the bill quite nicely, as the loop-out keeps the gaming 'competitive' while the capture looks great. Pros: - Really captures at 1080p 60fps, and delivers sharp images (instead of blurrier 30fps ones you'll find on cheap USB 2.0 MJPEG-based capture cards). YUY2 (the video format) is chroma subsampled though, which means that really small text may have a bit of discoloration, but for games it's not really an issue. - Low latency capture (at least from what I can tell in OBS preview) - Loop out (yay) - Works with Linux as a simple V4L2 capture device - Sound is nicely in sync - Price (I got it for like ~$40 or so, and haven't found anything this good at this price point - heck, it outclasses my AverMedia Live Gamer Mini I bought used at $60) ==== aja and other stuff cost ... *much* more. https://www.aja.com/products/u-tap-hdmi 439$ https://www.amx.com/en/products/uvc1-4k even costlier, 800+! Anyway, in all cases cable (usb) might be limiting factor, too? I really hope this HAMA device actually just was plugged in wrong port or via wrong cable, otherwise I think it will be wise to replace it with something else (sadly cheap-end devices may change their guts without changing appearance, so ...russian roulette!)

Another pretty interesting bug: referenced EDL is actually mono
by Stefan de Konink 08 Feb '23

08 Feb '23

What about this one. 1. Create a project where you put in a nice stereo audio track 2. Put it on the time line. 3. Save the project "stereo track" 4. Create new project (obviously stereo) 5. Load the project "stereotrack" as "Reference EDL" 6. Drag it into the timeline 7. Play; notice that is actually mono audio on two stereo tracks. -- Stefan

gnu debuglink

According to https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html you should add another objcopy command objcopy --add-gnu-debuglink=foo.debug foo for debuglink method. While it also says some versions of strip command also can do this part automatically I think we can try first method just for seeing now it works (I suspect fedora debug packages not showing all info actually related to this missing command). build-tested on termux only.

For next month: more build BSD fixes!

FreeBSD 13.0 was driving me mad full day! For some reason gmake included there was not setting python variable, so I spend a lot of time trying to imagine some workaround not breaking all other configs .. I think those patches works on both FreeBSD 12.3 And 13.0 and NetBSD 9.2 And Slackware 15.0 And termux .. uffff...

executable stacks are bad...m-kay?
by Rob Prowel 02 Feb '23

02 Feb '23

Thought this went away in my Jan-2023 git pull, but apparently not. Looked in my dmesg output and saw this again. process 'sharebin/cingg2301/bin/cin' started with executable stack Why? A consequence of the plug-in system? a poorly designed 3rdparty library? an oversight? stack segments are generally marked as no-exec to protect against using them to execute rogue instructions by saving those instructions in auto-vars on the stack that could be executed by fudging the return address of a function. Just looking for an acknowledgement of this, and any relevant related history at this point.

libtiff 4.4.0 fix?
by Andrew Randrianasulu 02 Feb '23

02 Feb '23

For some reason libtiff was erroring out for me on first build for both debian 11 and ubuntu 16.04 I think this patch to libtiff itself fixes it, but then it was working if I remove libwebp and rebuild it .... strange, strange.
