[MPlayer-users] Installation question

[Gordon A. Campbell]

Hello, First time user/installer here. I have succesfully been able to
install (thank you all very much). However, for my particular purpose of
using this tool, I have not yet been successful. My specific goal is to
extract a jpeg from a Quicktime movie. I am neither a Quicktime nor C
expert, but have been spent the day reading the installation guides and
this forum. So, I hope you'll be understanding in what may seem to others
as a simple goal. I believe I am missing the library for the ability to
create a JPEG. However, I do not know where to find it or where it needs
to be placed.  Also, there was not an (vo_jpeg.o) in the libvo file.
This is just a guess though, so please read on. Finally, after reading
many of the threads in this forum, I am well aware the
"stupid/dumbass/RTFM" questions are um, frowned upon. It is with deep
regret that I am asking for help. Thank you, gordie.

Finally, as an experiment I tried a different output type to generate some
errors that I hoped would assist me.
