Hi Amit
The encoder does only accept YUV raw video files (I do not know any
encoder which takes anything else as input). AVI is just a video
container, no coding format, there are several tools to extract the raw
video data from an AVI file (just serach google for avi2yuv or avitoyuv
etc.).
If you have a raw YUV file with 4:2:0 color subsampling the number of
images can be calculated as follows: (number of images) =  (file size in
bytes)/[(image height)*(image width)*1.5]
Greetings
Tobias
