Hi, Previously i was using SecureToken 2 for mp4 files, but now i start using SMIL files for ABR. However i am wondering how i shall construct the SMIL and include SecureToken as per the MP4 files. This is an example of request URL: ```auto sample.mp4/playlist.m3u8?myTokenPrefixstarttime=1395230400&myTokenPrefixendtime=1500000000&myTokenPrefixhash=TgJft5hsjKyC5Rem_EoUNP7xZvxbqVPhhd0GxIcA2oo= ``` and this is an example of a SMIL file: ```auto

```
