recording uncompressed rgb avi

[slitcher]

It seems the last ffmpegcolorspace did the trick but I don't understand why.
In the command:

gst-launch.exe filesrc name=filesource location=C:/folder/file.avi !
avidemux name=demux demux.audio_00 ! queue ! decodebin2 ! audioconvert !
autoaudiosink demux.video_00 ! queue ! decodebin2 ! *ffmpegcolorspace !
video/x-raw-gray,width=320,height=240 ! ffmpegcolorspace* !  autovideosink 

Why do I need both ffmpegcolorspace converter? Removing it will result in a
pipeline freeze. Is it because autovideosink doesn't have the proper caps?
Is there anything I misunderstood in the pipeline concept? For instance, why
a second videoscale is not needed?

In any case, it works now! Thanks a lot for your quick help! :)
