Yes, it is, but I think it's imcomplet...

In my MDK 9.0, There is a package named 'libmjpegtools'. You can found some 
informations about here:

Mjpegtools is very easy to use with the pipe process. I use to showing and 
convert DV file to MPEG, DIVX, MOV and others formats...

Yes ! you can ! 

I have a DV file 'capture001.avi' grabed with kino from my digital camera. 
There is 1200 frames in this file. If i want to see only the frames between 
the frame ID 200 and the frame ID 300, i use :

lav2yuv -o 200 -f 300 capture001.avi | yuvplay

Look lav2yuv for more informations...
