how to reduce output size while capturing webcam video using ffmpeg ?
27 novembre 2014, par Chris SnowI am capturing output from my webcam as follows:
ffmpeg -y -an -vcodec rawvideo -f video4linux2 -s 320x240 -i /dev/video0 out.mpg
I would like to trade off quality of the output in order to reduce the amount of data that is recorded but I don't know what options to set.
Any pointers will be appreciated - video encoding is a completely new area and unknown area of computer science for me.
