How to find color space of QVideoFrame in QVideoFilterRunnable::run
mikeitexpert last edited by
I need to know pixel color space of frames in the below cuz I need to convert it to the opencv's BGR color space.
QVideoFrame QVideoFilterRunnable::run(QVideoFrame *input, const QVideoSurfaceFormat &surfaceFormat, QVideoFilterRunnable::RunFlags flags)
I have tried
which gives me "Format_YUYV" and it is not enough cuz apparently there are different versions of this color space. (https://en.wikipedia.org/wiki/YUV)
Please let me know how I can get possibly more details.
There is also below which allows me to query more details about the fame properties but I don't what I need to query for
QVariant QVideoSurfaceFormat::property(const char *name) const
If you are using Qt 5.8previous, Can you confirm with the latest version Qt 5.12,again?
These report is also closed, but when I check Codereview, it looks like support only QtQuick.
Therefore, I feed that it necessary to confirm the operation in C ++.
No it matches only one format:
QVideoFrame::Format_UYVYis Y′UV422 with (u, y1, v, y2)
QVideoFrame::Format_YUYVis Y′UV422 with (y1, u, y2, v).
