Bug ID: 107373
Summary: Screen recording stutters when SteamVR is running
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: haa...@frickel.club
QA Contact: dri-devel@lists.freedesktop.org
Filed for radeonsi but the cause may very well be somewhere else.
RX 480, with mesa git, linux 4.18 and drm-next-4.19-wip.
Typically 60 fps screen recording works quite smoothly, but when SteamVR is
running the produced video is stuttering badly. The actual rendering and
displaying is still smooth, only the recorded video is affected.
Example video: https://youtu.be/yU_SKilk0p8
That's my gstreamer pipeline I use for recording:
gst-launch-1.0 -e ximagesrc display-name=$DISPLAY use-damage=0 startx=0
starty=0 endx=1919 endy=1079 ! multiqueue !
video/x-raw,format=BGRx,framerate=60/1 ! videoconvert !
video/x-raw,format=NV12,framerate=60/1 ! multiqueue ! vaapih265enc
rate-control=cqp bitrate=2000 ! video/x-h265,stream-format=byte-stream !
h265parse ! multiqueue ! matroskamux name=muxer pulsesrc !
audio/x-raw,channels=2 ! multiqueue ! opusenc frame-size=40 complexity=6 !
multiqueue ! muxer. muxer. ! progressreport name=Rec_time ! filesink
