AlpineLinux uxplay video hickup.

[wenerme]

I use alpine on amd64 as host. uxplay works like stop a will then works again.

When hickups happens, the cpu will be lower.

I tried using lan instead wifi, the problem still exists.

Sometimes the video quality will be lower, but not hickups, when hickups, the video quality is quite high.

Tried glimagesink, same problem, but full cpu load

we now have an alpine 1.39 "SYS" test installation on x86_64 (Intel i7) with KDE plasma

Only weirdness is that in an X11 (as opposed to Wayland) session, "uxplay" or "uxplay -vs xvimagesink" causes an error that terminates the user session and restarts sddm. see #259
Seems that alpine + GStreamer's xvimagesink don't work together under X11. Not sure how to debug this.

var/log/messages shows:

Jan 18 15:20:05 [host] user.notice libddcutil[3617]: libddcutil terminating.
Jan 18 15:20:05 [host] user.err pulseaudio[3700]: [pulseaudio] stdin-util.c: Lost I/O connection in module "module-gsettings"
Jan 18 15:20:05 [host] authpriv.info : pam_unix(sddm:session): session closed for user 

• We cannot reproduce your video "hickups", maybe a network issue.

Thanks, I will add more logs about the hickups, I tried cable network, same problem.

I found the same problem about the uxplay -vs xvimagesink trigger relogin, but ximagesink works fine, I don't know how to use wayland yet.

If you wish to report the xvimagesink problem to the alpine linux bugs reporting system, it can be simply demonstrated by

 gst-launch-1.0 videotestsrc ! videoconvert ! xvimagesink

(works fine with xvimagesink -> ximagesink)

Note that this is seen when running KDE Plasma 5.27 in X11 on alpine 3.19 on X86_64 GStreamer 1.22.8

EDIT: I reported it https://gitlab.alpinelinux.org/alpine/aports/-/issues/15698
