Wouldn't this be so much simpler?
-l num
Specifies the number of loops (default: 1 loop)
The ranges of images will be looped through `num' times, by
default just once. The value of 0 will loop indefinitely.
The -n option in ppmtoy4m and lavpipe use 0 to mean all. For lav2yuv it's -f
0 to mean all frames. jpeg2yuv and png2yuv use -1 for all.
I suggest using -n for frame count. head and tail use -n for line for number
of lines. -f seems like it should take a filename as an argument, like tar
and grep.
Why is it, jpeg2yuv and ppmtoy4m? How about jpegtoy4m? YUV also refers a
colorspace, while y4m is probably only used to refer to a stream format also
known as YUV4MPEG, read with functions like y4m_read_stream_header().
