[XviD-devel] [BUG] BFrame encoder doesn't force intra for 1st frame

Oops, that might have been me, when changing timecodes. 
Strange that I never had problem with a missing I-Frames...?

The correct (old) position might have  been here:




inc_frame_num(pEnc);
		
#ifdef _DEBUG_PSNR
	image_copy(&pEnc->sOriginal, &pEnc->current->image,
		   pEnc->mbParam.edged_width,pEnc->mbParam.height);
#endif
	emms();




just before the 

/*%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
* Luminance masking *
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% */


stuff (sorry, I have wrong linenumbers at the moment). 

Can anybody check on this?
