[Opalvoip-devel] Weird Behavior Encountered in PTLib 'PVideoOutputDevice_Window' Class

[KC O. <kco...@gm...>]

Hi All,

Need some advises and help on the weird behavior I have encountered in
PTLib "PVideoOutputDevice_Window" class when I try to do a h.323 voip using
opal with ptlib in window platform.

I used opal sample project (simple) for a quick H.323 testing, and the
problem I encountered, is whenever I try to hide the Video output windows
(i.e. either Local Video window or Remote Video window). It is not working
as expected.

I dive down into the issue by using spy++ to inspect those mentioned video
output windows, and noticed that whenver I sent a'Hide' window msg (i.e.
WM_SHOWWINDOW), there will be subsequent message 'Show' window msg received
also by the output window, causing
the the video window not able to hide. Couldn't figure out where the window
msg come from.

Thanks you in advance.

Note: I tested also the ptlib 'PVideoOutputDevice_Window' class itself,
using 'vidtest' sample project. The class itself work as expected when I
try to send the hide window msg. but it is having issue when using it
together with opal library.

Librarys I have Tested
PTLib v2.12.6
Opal v3.12.7
