Hi,
I have about 4300 pictures in a folder (000_Images/2022/04/2022-04-10/).
I want to create a video from them, every picture should be one frame in
the video.
I'm using the following command: ffmpeg -framerate 25 -i
000_Images/2022/04/2022-04-10/*.jpeg -c:v libx264 -profile:v high -crf
20 -pix_fmt yuv420p -y output.mp4
Its starting, but after about 500 pictures ffmpeg is slowing down, while
the system load goes quickly up. It was hard to cancel the command, as
the load was above 80. :)
Here some log of the command:
mcll@mcllserver-i3:/home/VVCam$ ffmpeg -framerate 25 -i
000_Images/2022/04/2022-04-10/*.jpeg -c:v libx264 -profile:v high -crf

Why is this generating such a high load, and what should i do?
Thanks
