Bug ID: 376893 Summary: Bad performance of kaffeine when watching HD channels compared to VLC and other players Product: kaffeine Version: unspecified Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: mchehab+...@kernel.org Reporter: yuli...@mailbox.org Target Milestone: --- Created attachment 104205 --> https://bugs.kde.org/attachment.cgi?id=104205&action=edit kaffeine --debug using libVLC with args: -v Hello, I watch DVB-T2 HD channels in H.265 but the video stutters. This problem does not appear in VLC, SMPlayer or the Gnome Video player. I can record a movie in kaffeine, and watch it without stuttering with VLC at the same time. So it is not that the computer is not fast enough to handle it. If I play the record with kaffeine, all 4 cores are almost at 100% and the complete system (and the cursor) becomes a sluggish. (The sluggish cursor is a known bug/disadvantage of using wayland under heavy load.) If I play the file in any other player, the video and the system is completely fine, although the 4 cores are at ~ 80 %. I have no graphics acceleration via VDPAU for video decoding of H.265. I have an AMD RS880 chip, that supports VDPAU, but not for the 'newer' H.265. I tried many possibilities of libvlc parameters, but did not get it to work like in VLC. I was even unsure if those parameters had any effect, partly. The attached logs show kaffeine --debug with libvlc -v and -vv, as well as a working vlc -vv for comparison. Some parameters of my system: Fedora 25, but with vanilla linux 4.10, x86_64. I use Gnome 3 under wayland. kaffeine from today's GIT. Any ideas? Thanks in advance. -- You are receiving this mail because: You are watching all bug changes.
