Dear all,
I could identify the reason for the behaviour. In
FFmpeg-master\libavdevice\gdigrab.c, gdigrab_region_wnd_init() *WS_POPUP
*is used for CreateWindowEx(),
Why? WS_POPUP is not expected for main windows. Is it possible to fix this?
Best regards,
Norbert
/**
* Initialize the region outline window.
*
* @param s1 The format context.
* @param gdigrab gdigrab context.
* @return 0 success, !0 failure
*/
static int
gdigrab_region_wnd_init(AVFormatContext *s1, struct gdigrab *gdigrab)
{
HWND hwnd;
RECT rect = gdigrab->clip_rect;
HRGN region = NULL;
HRGN region_interior = NULL;
DWORD style = *WS_POPUP *| WS_VISIBLE;
DWORD ex = WS_EX_TOOLWINDOW | WS_EX_TOPMOST | WS_EX_TRANSPARENT;
rect.left -= REGION_WND_BORDER; rect.top -= REGION_WND_BORDER;
rect.right += REGION_WND_BORDER; rect.bottom += REGION_WND_BORDER;
AdjustWindowRectEx(&rect, style, FALSE, ex);
// Create a window with no owner; use WC_DIALOG instead of writing
a custom
// window class
hwnd = CreateWindowEx(ex, WC_DIALOG, NULL, style, rect.left, rect.top,
rect.right - rect.left, rect.bottom - rect.top,
NULL, NULL, NULL, NULL);

Dear Developers,
I would like to use ffplay.exe in may application to play video files
and to show live video sources. Thank you for that great application
that covers all these possibilities! However as soon as ffplay.exe loses
the input focus the fullscreen window of ffplay is iconified. I aloready
reviewed the source code (event loop) but was notz abel to identify the
handling that causes that behaviour.
Is it possible to change the behaviour so that ffplay stays maximised
even if the focus is lost or the ffplay windows is covered by an other
window? Possibly by using a command line option?
I think that depends on underlying SDL library.
Best regards,
Norbert Marouschek.
