Yep, it fixes the issue.

It looks that the code could be a bit more cleaned up, as with the 
attached patch, there is such construction:

         if (coded) {
                 pix_mp->num_planes = 1;
                 vpu_fmt = fmt;
         } else if (ctx->is_encoder) {
                 vpu_fmt = fmt;
         } else {
                 vpu_fmt = fmt;
                 /*
                  * Width/height on the CAPTURE end of a decoder are 
ignored and
                  * replaced by the OUTPUT ones.
                  */
                 pix_mp->width = ctx->src_fmt.width;
                 pix_mp->height = ctx->src_fmt.height;
         }

Common 'vpu_fmt = fmt' can be moved out of the above if-else block.
