<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hi all, I'm trying to use GStreamer on Wayland and it seems to have some problems... This pipeline: gst-launch-1.0 ximagesrc startx=1 endx=3839 starty=0 endy=2159 ! video/x-raw,framerate=30/1 ! videoscale method=0 ! ximagesink works well on Xorg, but not on Wayland. On wayland I have this error: <span style="color: rgb(219, 222, 225); font-family: Consolas, "Andale Mono WT", "Andale Mono", "Lucida Console", "Lucida Sans Typewriter", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Liberation Mono", "Nimbus Mono L", Monaco, "Courier New", Courier, monospace; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(43, 45, 49); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">Setting pipeline to PAUSED ...

X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 73 (X_GetImage) Serial number of failed request: 52 Current serial number in output stream: 52 Is there any fix for this since Xorg is going to be deprecated everywhere? :) Thanks Davide </body> </html>
