  Indicates whether to generate SPS and PPS at every IDR. Setting it to 0 disables generating SPS and PPS at every IDR.
Setting it to one enables generating SPS and PPS at every IDR.

I can spot evident hard-coding of mask and bit shifts in here. In order to
continuously improve this driver code, I would like to see this (and the
following) magic number being defined with well named macros as a preparation
patch to this feature change.

regards,
Nicolas

Hey Jackson,

as with the previous review, the title needs to be adjusted 'wave5:' is
not enough.
Also 'Support to prepend sps/pps to IDR' sounds a bit weird and doesn't
quite match what you describe below.
How about:
'Support SPS/PPS generation for each IDR'

My suggestion:

Provide a control to toggle (0 = off / 1 = on), whether the SPS and PPS
are generated for every IDR.

Greetings,
Sebastian
