If you use numbered labels I believe you need to append the jump
jnz 1b
instead of
jnz 1
if you mean the 1: label that comes before.
At least that is what I see in e.g. libavcodec/x86/snowdsp.c and many
more files.

You seem to have lost the very first "static". Otherwise it looks ok to

Looks good to me as well.
If nobody has any other comments I will try to get it applied to MPlayer
soon to try to keep the codebases in sync (or if I'm too slow
anyone with commit access there is of course free to apply them).
