Not sure what AV_PKT_FLAG_KEY is supposed to mean. The assumption to

Is it not a application flag ?
Seems for at least H264 it doesnt have much meaning to application. If
the packet dts value is in the stream index_entires then that
represents a key frame for sure ( hopefully :)
What if there are no index_entries ? Whats a key packet then and how
to determine ?
Just trying to clear up my own confusion with this.

For h264, the key frame network abstraction unit of the packet will be
of type IDR, instant data refresh.
I believe NAL type 5.
