To embed mplayer into a window you must know its ID. Window IDs have a
relation with the WindowHandle, but that value must be somehow
"translated" to be understood by X11 (or Windows). I don't know how to
translate it :(.
For example, If I use Format('%x', [Self.WindowHandle]) I get the Hex
value BB5380, then, using the wininfo tool I can get the ID. Just run
xwininfo and click on the window you want to embed mplayer into.
In my example I got:
xwininfo: Window id: 0x2800048 "BB5380"
Absolute upper-left X: 662
Absolute upper-left Y: 270
Relative upper-left X: 1
Relative upper-left Y: 24
Width: 320
Height: 240
Depth: 24
Visual: 0x20
Visual Class: TrueColor
Border width: 0
Class: InputOutput
Colormap: 0x22 (installed)
Bit Gravity State: NorthWestGravity
Window Gravity State: NorthWestGravity
Backing Store State: NotUseful
Save Under State: no
Map State: IsViewable
Override Redirect State: no
Corners: +662+270 -1744+270 -1744-258 +662-258
-geometry 320x240+661+246
As you can see, the first line displays the same Hex number I get from
Lazarus, and 0x2800048, this is the value mplayer expects.
So, to embed a movie into a window, when you know the window Id, you
just launch mplayer using this options:
mplayer -wid 0x2800048 /home/leonardo/Imágenes/Fotos/2009/11/21/mvi_0260.avi
Please, if any you know how to translate BB5380 to 0x2800048 I'll be
glad to learn.

and you know how to tell MPLAYER to show the video in a specific window? (using
WINDOWS, and glutCreateWindow).
thanks
Philippe

Assunto: Re: [Lazarus] Play video from memory
Yes, you can!.
1) Load your Video to a TStream (TMemoryStream for example).
2) Use TProcess to execute "mplayer -", the "-" is the parameter.
3) Send your stream to the standard input of the process.

Thank you Leonardo,
I saw it before but it doesn't seem there is a way to pass memory to it
or I couldn't find out how.
Do you know?
Regards,
Ara

Hi,
Any one know a library or way to buffer video file into memory and then
pass it to player?
Any simple player do the job but it should support a way to open file
from memory.

Ara
