I am recording the video using FFmpeg command in .mkv format with FHD resolution using libx264 software encoder in my system. After some time the recording stops by itself.
By debugging what I observed is it is consuming more RAM and increasing rapidly and kills the recording process. Can anyone suggest the solution for this?
Here is the command I am using to record the video:
ffmpeg -f v4l2 -framerate 30 -video_size 1920x1080 -i /dev/video2 -c:v libx264 -b:v 15M -preset veryfast -pix_fmt yuv420p output.mkv
Here I am attaching the logs
regarding to the free RAM space:
