Can I change the values of x264 parameters on the fly? The only parameter
which I want to change is keyint.

ffmpeg -f avfoundation -video_size 800x600 -framerate 30 -i 0  -vcodec
libx264 -x264-params keyint=30:scenecut=0  -acodec aac  -b:v 1M -b:a 192k
-f dash  -use_template 0 -use_timeline 0  -single_file 0  -streaming 1
-seg_duration  1 sairam.mpd

This is the command which I am using right now.
