Encoder output packets are all marked as key frames? #26

Closed SeeRich closed 1 month ago

SeeRich commented 1 month ago

I think I ran into this issue when trying to post process videos created using this encoder. I was trying to use libavformat fast seeking functionality via av_seek_frame and noticed that it kept returning the wrong frames (ie not actual keyframes).

should the above code pull the key frame flag from the buffer metadata? Like in the example code below?
