Beagleboard-xM DVSDK4.01 Encoder not working

Hello,

I have installed DVSDK 4.01 on Beagleboard-xM successfully.
I am able to run decode demos successfully, but i am not know how to use encode command

./encode -v /usr/share/ti/data/videos/davincieffect.mpeg4
Encode demo started.
Error: Failed to detect video standard, video input connected?

Basically i extracted Raw video from the .mp4/.avi file using FFMPEG. [FFMPEG installed in my Linux PC]. Then i tired to give this raw video as the input the Encoder software but it didn’t work, Does DVSDK supports this operation?

Question:
1) Does DVSDK Encoders support file based Encoding??

2) From where does the Encoder software gets put from??

3) How to install FFMPEG into DVSDK 4.01??

Thank-you,
Naveen Kumar.S
