Issue about dynamic change resolution in IPNC_3.5.0

Hi all,

     We are using the IPNC RDK 3.5 with a DM8127 to encode stream H.264 and JPEG, and would like to be able to change the resolution of a channel on the fly.  I have read the thread:http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/249486.aspx.

   I have updated the width,height and pitch info in ispLink, and set the flag rtChInfoUpdate.

   I noticed that EncLink_codecDynamicResolutionChange has been invoked.

   But my problem is H264 stream seems right but JPEG are not.

  the first image is the origin 1080p jpeg.

  the second is the image after change resolution, I set it to 720P, but it still be 1080p, and content are not good.

Help!
