[FFmpeg-user] how to concate two wmv files ?

[Bob]

Dear list,

Greetings !!

I like to upload video files to vimeo. The source files are actually 
.wmv files which I first need to join and then remove some part from the 
concatenated  file with handbrake graphical utility. Finally I have to 
convert the resultant file to flv and upload to vimeo.  Can any one 
suggest me a good approach along with ffmpeg command line ?

Thanks and regards,
Bob
