[x264-devel] redundant SPS/PPS

[Rahul Arvind Jadhav]

Is it necessary to "mandatorily" add SPS/PPS before every non-consecutive
IDR frame even though the SPS/PPS to be sent are same as sent previously
especially in context to "reliable transport mode" used such as TCP?

 

For e.g. After checking out YouTube H264 streams, I found that most of the
SPS/PPS are redundant and transmitted before every non-consecutive IDR
frame.

 

I assume the redundancy holds good for certain transport modes such as UDP,
but for TCP it might be counter-productive.

 

So if i dont send multiple SPS/PPS will there be any interoperability
problems and before that, is it ok to do as per the specs?

 

Thanks,

Rahul
