Cinelerra : libXv.so.1 not found

[marcos <marcosbezerra@altern.org>]

Hello to the community !

Someone can tell me where to find this shared library : libXv.so.1 ?

I'm using Debian/Sid,
I've just installed Cinelerra to edit my videos, but when I try to run 
it I get the following err message:

# cinelerra &
cinelerra: error while loading shared libraries: libXv.so.1: cannot open 
shared object file: No such file or directory

(just a detail : Cinelerra is a rpm package; I downloaded it, then used 
alien, then "dpkg -i")

I had a look on the shared libraries asked by cinelerra:

# ldd /usr/bin/cinelerra
      libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40021000)
      libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x400e7000)
      libXv.so.1 => not found
      libpthread.so.0 => /lib/libpthread.so.0 (0x400f6000)
      libpng12.so.0 => /usr/lib/libpng12.so.0 (0x40147000)
      libz.so.1 => /usr/lib/libz.so.1 (0x40168000)
      libdl.so.2 => /lib/libdl.so.2 (0x40179000)
      libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4017c000)
      libm.so.6 => /lib/libm.so.6 (0x40233000)
      libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40256000)
      libc.so.6 => /lib/libc.so.6 (0x4025e000)
      /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

then I tried to find a debian package including libXv.so.1:

# auto-apt check /usr/X11R6/lib/libXv.so.1
*
# auto-apt check /usr/lib/libXv.so.1
*
# auto-apt check /lib/libXv.so.1
*

==> no answer !

Then, just intuition : libX11.so.6 and libXext.so.6 come from the xlibs 
package, maybe I can find what I'm looking for in it. (starts with 
"libX...").

But unfortunately a "dpkg -L xlibs" doesn't find libXv.so.1. (I have 
xlibs 4.2.1-14)

I'm sad now.

Can you help me ?
Just a tip and I'm happy...

Thanks / Merci
