problem while switching to newer version of ffmpeg to convert .mpg to .3gp
Hi, i am using ffmpeg to convert .mpg to .3gp file. command line: ffmpeg -timestamp 'date -u %T' -i 1.mpg -g 25 -b 28 -r 4 -s qcif -vcodec h263 -an 1.3gp This working fine with my , Suse linux 10.0, -ffmpeg 0.4.9.7.pm svn 20060730.i686.rpm -libffmpeg 0.4.9.7.pm.svn 20060730.i686.rpm but,when i installed it in my another machine ,i didn't find older version so ,i installed -ffmpeg 0.4.9.7.pm.svn.20061008.i686.rpm -libffmpeg 0-0.4.9-7.pm.svn20061008.i686.rpm My commandline working fine,but no effect of -b 28(bitrate option), In ffmpeg options i found that they won't provide any -b option. i can't able to figure out where might be the problem? Thanks & Regards, -Samir.

The current policy is that this list supports the current svn, built from source. If you use a Suse package, questions should go to the *package* maintainer.

Giving the command line is good, but you should also give all output messages.
In ffmpeg options i found that they won't provide any -b option.
I would be very surprised. But the unit for -b has changed recently, from kilobits to bits. Try -b 28000 with latest svn.
i can't able to figure out where might be the problem?
Thanks & Regards, -Samir.

-b 28 is 28 *bits* per second. Maybe you meant "-b 28k"? Even that is rather low. The default (if no -b option is given) is 200k bit/s.
In ffmpeg options i found that they won't provide any -b option.
It *is* in the man page. -- G. Stewart - godwin.stewart at gmail.com Only adults have difficulty with childproof caps.
