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.
