 # threefive works very well with ffmpeg. 
 * __ffmpeg changes the SCTE-35 (0x86) stream type to bin data (0x6)__
 * __threefive is the only SCTE35 tool that parses both  SCTE-35 `(0x86)` and bin data `(0x6)` stream types__.  
+* __the threefive cli tool can convert the stream_type back to `0x86` after ffmpeg changes it.
