Dear Mr Eugen
I apologize if I was not clear in explaination. I am using ffmpeg libraries
inside my code (not using the ffmpeg.exe) in order to create a mov file both
in D10 
and in xdcam format for avid. Using old libraries the final file works, that
is you
can see it on QT and importing it on avid.  Inserting new libraries, the
result is in 
a white screen.  With the new libraries, the only difference is in settings
that is the original code:
 pQTCodecCtx->flags |= CODEC_FLAG_LOW_DELAY;  // Specific for AVID IMX 50

is changed bypassing the last line (the two codec flag are not defined at all).
Now the result is that the final mov file doesn't work (white screen on QT
and on 
avid media composer).
If you give me your mail I can send you the piece of code with all settings.
best regards
