batch mpeg encoding

[d47]

hi, i was wondering if any knows of a simple way to batch process videos with ffmpeg, mencoder, vlc or what have you. currently i use ffmpeg with the following command:

ffmpeg - i -s 320x240 -vcodec mpeg2video -acodec mp3 -ac 2 -ar 44100 -r 24

i cant seem to get mencoder to resize the video.
also is there any way to set the output quality for the encoded files.

thx for any tips.

VLC command line:
"...\vlc.exe" %1  --sout=#transcode{vcodec=mp2v,vb=600,width=320,height=240,acodec=mp3,ab=128,samplerate=44100}:std{access-video=file,mux=ps,dst=%1.mpg}

set vb value to set output quality

No, it's simply bitrate, much like audio bitrate.

ok well i found a solution so for any1 who reads this in the future here it is:

for i in *.avi; do ffmpeg -i "$i" -s 320x240 -vcodec mpeg2video -acodec mp3 -ac 2 -ar 44100 -ab 192 -r 24 "$i".mpg; done

be sure to change the *.avi to whatever the file extension is that your transcoding from and to change 320x240 to the resolution of your players screen, if you run ffmpeg -h you get a list of all the available options that you can set, for example to set the bitrate to 600 use "-v 600" etc. also in case you didnt notice ffmpeg is a program for linux i dont know if there is a windows version and the "for i in blah blah" is bash script and wont work in windows, you must have ffmpeg installed to be able to use the ffmpeg command.

thx and hopfully thats usefull to some people ^^ and i should really have known this before now =/

Hi all if you were looking for a windows batch mpeg encoding software i have written one to suit mencoder...

have a look at
http://sourceforge.net/projects/smsg/

It is a c# frontend and you'll probably need .Net 2.0 framework installed.
If you download the setup it pre-packages mencoder, mplayer, smsg and all the codecs...

It is a very simple batch mencoder trans-coding app!

cheers matho.

In case anyone needs a Windows app, I use MediaCoder 0.5.1-r9.  It's a GNU project also.  Same settings apply as above and depend on the device in use.
