[FFmpeg-user] last frame missing from mpeg2 and mpeg1 encodes

With a ten-frame input I'm getting the right length, but a green bar over the end frame. With a 100 frame input i'm getting the same result as with 1000 frames, one missing frame, a 99 frame output. I'm enclosing both here, with their outputs:

The console from the outputs are below.

Thanks
