[Libav-user] -tune zerolatency

[HONGBO LI]

h264 encoder I frame using zerolatency by using following :
 av_dict_set( &options, "tune"  , "zerolatency", 0 ); 

I found that encoded I frame the first_mb_in_slice is not 0, it is 480 instead.

But I do need first_mb_in_slice  is 0, Is there anyway I can got it while using zerolatency?


Thanks
