Capture Specific Window by their title (Like GDIGrab do that )

[rplabon]

gdigrab works great on -i desktop but when i use -i title the conference area is black. does screen-capture-recorder have window capturing support?

[rdp]

what OS?

[rplabon]

Windows 8.1. 64 bit.

[rdp]

I think the problem is the conference area itself is a different window than the one its selecting, no easy work around for gdigrab I'm afraid (is this a bug report for screen capturer or gdigrab BTW)?

[rplabon]

Hi,thanks.

Its in GDIgrab.

Using FFMPEG(dshow) and screen capture recorder , i wanted to get output for specific window.

Is that possible by modifying some code in screen capture recorder, so that it can capture particular window .?

Yes anything is possible :) I would just figure out some script to compute the proper HWND for you, but I might add it to screen capturer in the next half year or so

Hi @rdp ! I see that in build 0.11.1, You've added a new parameter: capture_foreground_window_if_1. Dies this mean that you now have the capability to capture individual windows ?

[rdp]

yes by HWND or "detect foreground" I believe

Thanks, but I seem to be somewhat lost..I'm trying to record a specific window and trace its location if I move it around. How can pass screen-capture-recorder the name/pid of the window ?

[rdp]

please see the README about HWND I'm not sure if it tracks a window that moves but it should...

Using HWND works and it tracks the window smoothly! I do have an issue though: When I resize the window, the mouse cursor is recorded in a weird way inside the previously occupied space. In addition, the area left behind when the window's size was reduced, is still displayed in the recording: Am I the only one experiencing this?

param track_new_x_y_coords_each_frame_if_1 help?

nope.. I think I've tried most possible combinations: with and without aero, specifying size, stretching, dedup, w/o mouse cursor. The same behaviour happens when I'm using ffmpeg's GDIgrab driver. I'm thinking that in order to solve this, I would have to somehow "flush" the current frame when the window is resized.

[rdp]

hmm that's odd...

For anybody who might be looking at this in 2022: it also produces the same black output as gdigrab on hardware accelerated windows, don't waste your time on it.

[wbtcpip2]

in 2022 with windows 10/11 to capture a single window you need to use windows Graphics Capture API (it works also on hardware accelerated windows)
