DM365 resizer from 320x240 to 720x576

I try to describe my problem:

i have to resize a 320x240 video into a 720x576 video.

I'm using gstreamer  and my video flow is:

udpsrc --> rtpjpegdepay --> TIImgdec1 --> TIVidResize --> TIDmaiVideoSink

if I receive a 352x288 mjpeg video all is ok, otherwise if I receive a 320x240 video the result is that the output of TIVidResize is always the same image ( the last "valid" image of the 352x288 video).

TIVidResize doesn't output any error.  I've tried to inspect the dm365 registers and seems that the resizer "boxcar" element is in error state.

I've also tried to resize a 720x576 video to a 320x240 video and it works.

Any idea ?

Thanks in advance,

Angelo
