No screen popping up in Fedora

[sourcecodere]

• I have read the FAQ.
• I have searched in existing issues.

Environment

• OS: Fedora 34 (wayland and intel GPU)
• scrcpy version: 1.18
• installation method: dnf (also tried manual way)
• device model: Samsung S10
• Android version: 10

Describe the bug
No screen is displayed. Stuck here:

$ scrcpy 
INFO: scrcpy 1.18 <https://github.com/Genymobile/scrcpy>
/usr/share/scrcpy/scrcpy-server: 1 file pushed. 6.9 MB/s (37330 bytes in 0.005s)
[server] INFO: Device: samsung SM-G973F (Android 10)
INFO: Renderer: opengl
INFO: OpenGL version: 4.6 (Compatibility Profile) Mesa 21.1.6
INFO: Trilinear filtering enabled
INFO: Initial texture: 1080x2280

Running with -Vdebug it is stuck on [server] DEBUG: Using encoder: 'OMX.Exynos.AVC.Encoder'.

No obvious error message in adb logcat and nothing in sudo journalctl -f.

I have tried:

• Different resolutions with -m
• All the different codecs
• A different phone
• adb shell screenrecord .... works

Not sure where to look/debug :-(

OS: Fedora 34 (wayland and intel GPU)

Does it work better with:

export SDL_VIDEODRIVER=wayland
scrcpy

?

If not, could you build the client manually (following the BUILD instructions, but in debug mode):

meson d --prebuilt-server=/usr/share/scrcpy/scrcpy-server
ninja -Cd

Then run it under gdb:

export SCRCPY_SERVER_PATH=/usr/share/scrcpy/scrcpy-server
gdb d/app/scrcpy
# in gdb: run

When stuck, Ctrl+C or Ctrl+z, and in gdb, execute:

thread apply all bt

Then post the backtraces.

Thank you

export SDL_VIDEODRIVER=wayland

Fixed it! Thank you very much!

[sourcecodere]

So in case anyone else struggles on Fedora with wayland:

sudo dnf install libdecor
SDL_VIDEODRIVER=wayland scrcpy

Thanks again @rom1v

Nothing to do.

Created a separate issue here: #3223

I'm still having the issue mentioned in the original post here despite having added export SDL_VIDEODRIVER=wayland to my shell config. Is there anything else I can do?

I'm on fedora 36, installed through copr zeno/scrcpy, libdecor is installed.
