Hi Varsha, How are you allocating the input and output buffers that are passed to your video encoder's process call? Make sure you are using contiguous buffers allocated by CMEM by calling Memory_contigAlloc() - suggest you look at how that's done in the original encode demo. The memory managed by CMEM should be correctly aligned on 128-byte boundary by default.
