Hi, This line is used for xvideo capability. However, the trunk branch doesn't contain related xvideo code. So, I think it was a bug generated by Morris while integrating his advanced ui to trunk (should be mpeg4 branch) .
Socrates: Could you revert the SVN to previous version? Barz 2007/2/1, Sam Gundry <sgun...@vpac.org<mailto:sgun...@vpac.org>>: Hi Socrates, I actually commented out this line yesterday, before receiving this email. :) Video images now display locally in both the consumer and producer windows. What should that line of code do? I haven't noticed anything out of the ordinary yet...
