is it possible to convert into Baseline profile using FFMPEG or other tools, or is there a way to do myself?

basic idea is to stream this video to android devices.

Answer 1

ffmpeg -i input_file.avi -vcodec libx264 -vprofile基线-预设慢-b：v 500k-最大500k -bufsize 1000k -vf scale = -1：480-线程0 -acodec libvo_aacenc -b：a 128k output_file.mp4

Answer 2

Handbrake is an excellent tool, has a command line utility (which basically uses FFMpeg), and lists here the commands to all their current profiles.

Considering you want a Baseline profile, the iPhone/iPod touch should do for you:

./HandBrakeCLI -i DVD -o ~/Movies/movie.mp4 -e x264 -q 20.0 -a 1 -E faac -B 128 -6 dpl2 -R Auto -D 0.0 -f mp4 -X 480 -m -x cabac=0:ref=2:me=umh:bframes=0:weightp=0:subme=6:8x8dct=0:trellis=0
