Agree, will change to use step_width/min_width = 64 in v5, not sure why
I changed from using step_width in v2 to begin with:
"
Changes in v2:
- Only align decoded buffer instead of using frmsize step_width
"

Found a note to change this to H264_PROFILE_CONSTRAINED_BASELINE from
the old v2 series. Will include such change in v5.

Will update in v5, thanks.
