VideoOutput in multiple threads rendering flicker
Whary last edited by
hi, We use VideoOutput for rendering YUV frames. but encounter some trouble as follows:
- it works well when a few channels of video rendered, and every single of channel is rendered through a thread with Qml's VideoOutput type.
- when we increase the number of video channnels up to 10, the render windows flicker sometimes at random. this kind of issue seems that the frame belong to window-A is rendered in window-B actually.
is there anyone meet the same issue?
it's apprecaite for any help.
P.S: our QT version is 5.6.2.(on Windows OS), and the the same bug on Linux with QT 5.9.8.
Hi and welcome to devnet,
You should provide a minimal compilable example that shows that behaviour.
You should also test your application against a more current version like the latest LTS or even Qt 5.14.
