I'm trying to Encode interlaced video and get a separate chunk of a bitstream for each field. I understand the regular schema look like this:
1) Prepare input surface (frame) containing both fields
2) Run EncodeFrameAsync
4) Read the output bitstream containing both encoded fields
I've found the mfxExtCodingOption.FieldOutput flag which I believe can help me. Can you explain how to use it to encode each field separately?
