Then if I wait for almost one minute, the video recording will appear in my video folders. The video record is a 5-10second test video, 14kB at size, so not something with a big resolution.. I remember spectacle worked fine with video recording, and started behaving oddly recently with, like.. 6.13 frameworks perhaps? Operating System: EndeavourOS KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 Kernel Version: 6.14.3-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-3470 CPU @ 3.20GHz Memory: 15.6 GiB of RAM Graphics Processor: Quadro K620 Manufacturer: FUJITSU Product Name: ESPRIMO E510 2419519 1 john 2025-04-28 05:53:05 +0000 Hi - could you please specify: * What type of recording you're performing - Rectangular Region, Full Screen, or Window? * In Configure > Video Saving, what format is chosen? This is the drop-down with options for MP4/H.264, WebM/VP9, Animated WebP, and GIF Thanks! 2419565 2 oat-lip-confront 2025-04-28 10:16:38 +0000 Hi Of course. So the video format is the default WebM/VP9. Seems that the freeze only occurs when I dona fulsscreen recording. My screen is 1680x1050 res. The rectangular selection and window records seems working fine, altho they also lag a bit when I stop the recording, but definitely not freezing the program itself. However, when I switched to MP4/H.264, all the freezing was gone, including fullscreen records. So perhaps it's something with the WebM. I noticed high CPU (70%) usage while using WebM,- and normal CPU usage (20%) during the MP4 session. 2419673 3 john 2025-04-28 17:06:51 +0000 Thanks - and it does in fact seem like there is an issue with WebM/VP9 specifically. What you're seeing seems to stem from the underlying issue https://bugs.kde.org/show_bug.cgi?id=488896 (also reported in a way that more closely resembles your observations at https://bugs.kde.org/show_bug.cgi?id=498691 ), so I'm merging this in with that issue for visibility. The good news is that as tagged on that other bug report, there's a major improvement in VP9 encoding speeds set to be released in the KPipewire component of Plasma 6.4.0 that should essentially resolve this. Thanks! *** This bug has been marked as a duplicate of bug 488896 *** 2419679 4 oat-lip-confront 2025-04-28 17:33:05 +0000 You're very welcome. Glad I could help. Thanks for looking into it :)
