Comment (by jamrial):

 "Conflicting stream par values" means there are two or more video streams
 in the same Adaptation Set with differing display aspect ratio (par). The
 @par value in the Adaptation Set must apply to all streams.

 In your case, the 852x480 stream with a 1:1 sample aspect ratio (sar) has
 a 71:40 par, which is different than the 1:1 sar 1280x720 and 1920x1080
 streams, both of which are 16:9 par, so it can't be in the same Adaptation
 Set.
 A workaround when using 1:1 sar streams would be making the 480p stream
 have a resolution of 832x468.
