[FFmpeg-user] ffmpeg does plays only one essence in quicktime reference conversion

Hello!
I am trying to convert a quicktime reference mov file exported from Avid MC
8.4.5. I am using the following conversion command:
ffmpeg -threads 0 -enable_drefs 1 -use_absolute_path 1 -i testseq.mov
-strict -2 -pix_fmt yuv420p test.mp4 -y
After hardly managing to get ffmpeg to reach all the referenced files, here
is the problem. In the converted mp4 the cuts (timecodes where source media
is changing in the sequence) gets through allright, but only on source clip
is used as source. The other source clips are just ignored.
Is this behavior "normal". That's it, this is all that is implemented so fat
in ffmpeg or:
1. I sould look for an updated version of the software
2. I am missing something out
3. I am doing something wrong
Here is the command with the output during conversion. After conversion no
error messages are displayed.
root at mediasync-ubuntu:/share# ffmpeg -threads 0 -enable_drefs 1
-use_absolute_path 1 -i test\ seq.mov -strict -2 -pix_fmt yuv420p test.mp4
-y
