[XviD-devel] ***SPAM*** UYVY decompression

[Erkan Ermiş]

Hi developper,

I am beginner in using XVid codec. I want to decompress an mp4 I-frame with size 704x576
but I am receiving run-time error at;
xerr = API_xvid_decore(dechandle, XVID_DEC_DECODE, &xframe, 0);

 The frame is valid mp4 I-frame i verified it.

It seems there is some invalid input parameters in "xframe"

How can I solve this, or what may cause this.

Thanks for you advices
