scrcpy can not start on android-x86 running in Virtualbox

[lencyforce]

I'm running Android-x86 nougat inside VirtualBox and connect to it using ADB over WIFI from another laptop.

Terminal:

C:\Program Files\scrcpy>scrcpy -m500 -b2M
C:\Program Files\scrcpy\scrcpy-server.jar: 1 file pushed. 0.4 MB/s (22470 bytes in 0.055s)
INFO: Initial texture: 320x480

And then got stuck here forever.

adb logcat:

07-24 04:45:00.033  1026  1026 D gralloc : Avoid registering a buffer in the process that created it. This may cause memory ordering problems.

By the way I compiled the android image from source code myself. So it it related to a missing kernel module or something?

Does it work with screenrecord?

adb shell screenrecord /sdcard/file.mp4

Does it work with screenrecord?

adb shell screenrecord /sdcard/file.mp4

No it doesn't work. file.mp4 is generated but the file size is always 0. The same error appears in the logcat window:

OK, if it does not work with native screenrecord, there is probably nothing scrcpy can do.
