[FFmpeg-user] image2 examples missing `-f image2`, can that be right?

[Jim DeLaHunt]

Hello, all:

I'm reading the documentation for the image2 demuxer[1]. It has three 
examples, in section 20.9.1 Examples.

ffmpeg -framerate 10 -i 'img-%03d.jpeg' out.mkv
ffmpeg -framerate 10 -start_number 100 -i 'img-%03d.jpeg' out.mkv
ffmpeg -framerate 10 -pattern_type glob -i "*.png" out.mkv

Those examples lack a `-f image2` option. I would expect that option to 
be there; after all, isn't the image2 format exactly what this section 
is trying to explain?

Should those examples instead read,

ffmpeg -f image2 -framerate 10 -i 'img-%03d.jpeg' out.mkv
ffmpeg -f image2 -framerate 10 -start_number 100 -i 'img-%03d.jpeg' out.mkv
ffmpeg -f image2 -framerate 10 -pattern_type glob -i "*.png" out.mkv

Or am I missing something?
