Powerpoint can't show a video with headers. I see green screen

I've created a video using ffmpeg that contains headers.

My script for creating it is:

ffmpeg.exe -f rawvideo -vcodec rawvideo -s 560x448 -r 40 -pix_fmt yuv420p -i C_L_560x448_40_static_maxSSIM_QP23_B2.yuv -vcodec rawvideo -qscale 0 -filter_complex "drawtext=fontsize=32: fontfile=FreeSerif.ttf: text='SSIM=0.961': x=(w-tw)/2: y=(lh/2): fontcolor=orange, drawtext=fontsize=22: fontfile=FreeSerif.ttf: text='Bitrate≤1800 [1873 kbps], Frame rate≥40 [43.98 fps]': x=(w-tw)/2: y=(lh/2+30): fontcolor=orange : box=1: boxcolor=0x00000099, drawbox=x=80:y=160:w=220:h=135:color=red@0.5" C_L_560x448_40_static_maxSSIM_QP23_B2_new.avi

Firstly, media player showed it as green screen. I downloaded Media Player Codec Pack and now show its correclty.

However, when I insert it in powerpoint 2016 I have the same problem of green screen. Do you know how to fix this?

vlc player can play it correctly. Is there any way to change the player of excel and use vlc player instead?

You're outputting an uncompressed stream. Use a codec instead.

ffmpeg.exe -f rawvideo -s 560x448 -framerate 40 -pix_fmt yuv420p
  -i C_L_560x448_40_static_maxSSIM_QP23_B2.yuv
