How to create the keyframe forcibly.

[toshinariagata]

I cannot create the keyframe(I-Frame) of h264 forcibly.
Would you please let me know how I can do it?
I use 5.4.70-2.3.0 bsp with i.MX8X C0 board.

I tried the following command, but I cannot create the I-Frame.

v4l2-ctl --device=/dev/video13 --set-ctrl=force_key_frame=

for i.mx8x, you can use "V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME" to force the key frame, see the source code:
