Huge use of processor/ webm incorrectly recording

[mark]

while i was making a test recording using kazam 1.3.1 i noticed that it was using 143+ of my processor which is more than any other application (with the exception of video editing software) has ever used.

also because i loved to use the Webm format in previous versions i decided i would use that and it messes with the video drastically showing only a vertical line, the debug info is:

also should mention that the mp4 format video/audio works however still uses way to much of my resources

[David Klasinc (bigwhale)]

There are problems with VP8/WEBM and GStreamer leaking insane amounts of memory. I'm already talking about this with GStreamer developers. H264 should be much better in this regard.

Can you please specify more precisely what is 'way too much resources'? Too much memory is consumed? Too much CPU? You need a lot of CPU power when recording 1920x1080 video at 15 frames per second and encoding it on the fly to H264 (or VP8). Kazam will now use all but one of your CPU cores.

I recorded a long video for testing, and I was seeing the swap being filled while the RAM was free. Is this the same issue? Will this be fixed?

@juan
Isn't Kazam screen recorder that manage swap/ram, that's a kernel issue so please open a new bug report typing in a terminal ubuntu-bug linux

Best regards
