How to record a specific window using ffmpeg?

Question

I use ffmpeg to record a window using this code:

ffmpeg.exe
-f dshow 
-y 
-i video=\"screen-capture-recorder\":audio=\"virtual-audio-capturer\":audio=\"Microphon         


        

Answer 1

I used this to record the prompt

ffmpeg -rtbufsize 1500M -f dshow -i audio="Microfono (8- Logitech USB Headset)" -f gdigrab -framerate 30 -draw_mouse 1 -i title="Prompt dei comandi" -pix_fmt yuv420p -profile:v baseline -y output\output3_xp.mp4
pause

But it works only with 100x20 (colxrow) fo the prompt or other divisible screen size, otherwise it gives me an error, this:

[libx264 @ 0000027c7ed66200] width not divisible by 2 (269x432)
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!

P.S.: I have this problem also with other windows that has not even width or height. I created a window with tkinter in Python and I get the error, then I gave the window some geometry (300x500) and it worked...

Strangely, the mouse is a little offset...
