VP9 lossless encoding not working

[GoogleCodeExporter]

What is the expected behavior? What do you see instead?
I expected a working output stream.
I got an error message.

----
Warning: Bad quantizer values. Quantizer values should not be equal, and should 
differ by at least 8.
1 encoder configuration warning(s). Continue? (y to continue)
----
also note: vpxenc does not wait for an answer here it simply aborts,...

What version are you using? On what operating system?
tried:
    vp8    - WebM Project VP8 Encoder v1.2.0-5319-g584c729
    vp9    - WebM Project VP9 Encoder v1.2.0-5319-g584c729
and
    vp8    - WebM Project VP8 Encoder v1.2.0-4722-ge55f602
    vp9    - WebM Project VP9 Encoder v1.2.0-4722-ge55f602

Can you reproduce using the vpxdec or vpxenc tools? What command line are
you using?
mencoder -lavdopts threads=8 -really-quiet -of rawvideo -o - -ovc raw -demuxer 
lavf -vfm ffmpeg -noskip -vf scale,format=i420 -forcedsubsonly -nosub -nosound 
-mc 0 "H:\TESTCL~1\test.avi" | vpxenc --codec=vp9 --lossless=1 --min-q=0 
--max-q=0 --threads=16 --width=640 --height=352 -o 
"H:\Output\test_07_56_58_0010_01.vp9" -

if I use:
mencoder -lavdopts threads=8 -really-quiet -of rawvideo -o - -ovc raw -demuxer 
lavf -vfm ffmpeg -noskip -vf scale,format=i420 -forcedsubsonly -nosub -nosound 
-mc 0 "H:\TESTCL~1\test.avi" | vpxenc --codec=vp9 --lossless=1 --min-q=0 
--max-q=8 --threads=16 --width=640 --height=352 -o 
"H:\Output\test_07_56_58_0010_01.vp9" -
instead, I get:
Error: Tried to set control 27 = 1
Failed to control codec: Invalid parameter
    rc_max_quantizer out of range [..0] 

=> would be nice if someone could post an example call how to use the lossless 
encoding.

Okay, one problem is fixed with the current version, but lossless still doesn't 
work,..

using:
[quote]    vp8    - WebM Project VP8 Encoder v1.3.0-290-ge18eb77
    vp9    - WebM Project VP9 Encoder v1.3.0-290-ge18eb77[/quote]
and
[code]ffmpeg -v -10 -i "H:\TestClips&Co\test.avi" -an -sn -threads 8 -vsync 0 
-r 25 -pix_fmt yuv420p -f yuv4mpegpipe - | vpxenc --codec=vp9 --lossless=1 
--end-usage=q --min-q=0 --max-q=0 --width=640 --height=352 -o 
"H:\Output\test.webm" -[/code]
lossless encoding doesn't work. :(
(only creates a 1kByte file)

'--passes=1 --pass=1' is required in the command line.

-> Problem solved.
