[Libav-user] Create an encoded interlaced frame

I would like to create an encoded interlaced frame using libav. The input is
simply a dummy image like in the libav example. I understand that the
interlaced video frame consist of two fields ( top and bottom ). My goal is
to get the fields data from the encoded frame. I wonder what is the right
approach to get the fields data.
I think I should have two dummy image and utilize avcodec_encode_video
function to generate the two frames which one is top and the other is bottom
field. Then, I need to set some parameters in the AVCodecContext in order to
set the encoder to do interlaced such as:
codecCtx->flags |= CODEC_FLAG_INTERLACED_DCT;
codecCtx->flags |= CODEC_FLAG_INTERLACED_ME;
Should I set the field_order to get the top / bottom field ? Please let me
know what you think and correct me if I am wrong. Thank you.
