[Lazarus] Play video from memory

[Philippe Lévi]

xwininfo ... linux ! ...


I need a solution for windows ...


I tried

whndl := WindowFromDC(wglGetCurrentDC())

but MPLAYER does not seem to like it, either in decimal format or hex format ...


and I do not know how to check if I get the resquested value  ... the handle of the window launched by glutCreateWindow ...

Leonardo,

Im not familiar with Mplayer but take a look at here:
http://wiki.freepascal.org/TMPlayerControl
And in MPlayerCtrl unit line 665 it just pass handle.

Do you have opinion about how to pass memory stream?

Regards,
Ara
