Description

Windows XP (SP3) QT (4.63)

If you zoom to greater than 17X in a QT window playing a video the video is repeated in the pixels rather than the colour value.

Images attached.

Also when saving images within a QT window, the outputted image is cropped. The original video of the attached image is 480x320. The attached screen-shots are 478x318.

Hello,

My config: Windows XP (SP3) QT (4.63) -- as yours

The save issue (wrong size) should be fixed. I was not able to reproduce the video
replication bug as shown in the screenshot. For my case, everything is ok with a zoom up to 100x. I tried with different videos and images, and with and without OpenGL enabled. Could you please tell me if the bug is with or without WITH_QT_OPENGL checked.

If you could also provide to me more information (like, did you try with other videos, and so on ...)

Thanks a lot,

Yannick

The bug seems to be gone now in Rev. #3513 looks like it was a ghost in the machine, either way both bugs reported here are fixed now :)

Thanks again!

Hello,

Thanks,
