qmdkqmlplay QML example flickering on top of Qt 3D scene about mdk-examples HOT 8 CLOSED

This change can fix the issue 98567ff

Indeed it fixed the issue, @wang-bin, thanks!

Now when I get back to tests, my app on windows crashed after several seconds without starting video. Only when I updated mdk-sdk from 0.10.4 to the newest 0.11.0 it starts working back again. According to mdk-sdk readme I suppose I can use it for free for any purpose without updating, but with an QR image in the last frame. Am I wrong?

Crash is not expected, and it was fixed recently. The readme says it's free for opensource or non-commercial softwares and i can give you a license key, otherwise you have to update your sdk every month. btw, qr is only rendered in opengl, so if using d3d, metal or vk renderer via qt rhi you will not see qr

Thanks for the explanations!

I have similar to example, but more complex application with Scene3D that previously works with blinking in 0.10.4, but now it crashes on start playing rtsp from local ip camera (it manages to show several frames). BigBuckBunny rtsp stream from internet works without crashing. The simple example here works fine with local rtsp. How can I debug it?

from mdk-examples.

Please show me your log, setLogHandler() can redirect the log. qtcreator can debug, ensure mdk.pdb exists

from mdk-examples.

Here is a log with crash. If set log handler and run debug it doesn't crash (but lag a lot).
mdk.pdb file exist near mdk.dll for each architecture, but qt creator doesn't show symbols.
I didn't find in google easily how to add path to .pdb in qt creator for gdb on windows, maybe you can help faster, thanks in advance!

Qt Creator 4.10.2
gdb 7.10.1 for MinGW 5.3.0 32bit

For now no problems on android arm-v7 (despite this general issue wang-bin/mdk-sdk#24)

from mdk-examples.

gdb does not support pdb files. you have to use cdb, and msvc toolchain may be required in qtcreator
