I think so, yes. ;)

That error is fairly self-explantory I think. The file image03.eli
apparently does not exist. OR, there's a format error - perhaps
the contents of the file are scrambled somehow.

That error is because I think you left out the "-v" in front of the 0.
lav2yuv is interpreting the "0" as a filename.
The command
"lav2yuv 0 -f 125 image02.eli"
probably should have been either
"lav2yuv -v 0 -f 125 image02.eli"
or simply
"lav2yuv -f 125 image02.eli"
image02.eli exists but it appears that image03.eli does not.

All those are caused by lav2yuv exiting without writing any YUV4MPEG2
info out - ypipe sees the end of file without ever seeing the
YUV4MPEG2 header or data

I don't know why the extra arguments were added - I didn't put them
there :) Now that those extra args have been removed it seems that
new typos have crept in (and perhaps a missing or misspelled filename).
"-v 0" disables message logging, "-v 2" enables debug output if the
program has any debug statements. It's up to the program to decide
what messages are "info" (usually "-v 1") or "debug" ("-v 2").
Thus the "-v 0" in the 2nd lav2yuv command is disabling all info and
debug messages. Since that is the lav2yuv that is complaining about
image03.eli not existing I think you want "-v 2" in that in order
to see any info/debug messages that are generated during the opening
attempt.
