I have put together a web page (http://westman.yi.org/ex1.html) containing
> input and output files from these scenarios (only a few seconds in > length) along with the command line parameters used and some diagnostic > output from mpeg2enc. There is also a screenshot zoomed in
on an instance of the problem (from the "-q 1" run.)
...and since that web page may not live forever, I might just as well post the relevant details (minus the big binaries) here as well.
The command used for encoding was:
mpeg2enc -v 1 -s -f 8 -B 260 -V 230 -b 3445 -q 1 -g 6 -G 18 -r 24 \
-4 2 -2 1 -n n -F 4 -p -I 0 -a 3 stream1.yuv -o stream1.m2v...which gave the following diagnostics from mpeg2enc:
