It's working great. Thanks. The video is clear. Finally, I've executed the
command as
./rfbproxy -x ../../files/q3.fbs | ppmtoy4m -S 420jpeg | mpeg2enc -b 10000
--no-constraints -f 3 -4 1 -2 1 -q 4 -P -N 1.0 -M 2 -E -10 -D 10 -a 2 -o
video.mp2
and
./rfbproxy -x ../../files/q3.fbs | ppmtoy4m -S 420jpeg |mpeg2enc -f 3 -q 4
-b 10000 --no-constraints -o video1.mp2
The fbs file has one minute session(video). When I execute this command, It
is taking around 4 minutes to convert fbs file to mp2. I feel this is quiet
unfair, so is there any options to reduce this conversion duration without
any loss in video.?
