Sorry I didn't state it clearly. What I meant is POC = previous POC +
2, not copied [1]. This is correct, since the frame is missing you
don't have better choices. I just wonder why not set field_poc? If I
add these two lines:
h->short_ref[0]->field_poc[0] = prev->field_poc[0] + 2;
h->short_ref[0]->field_poc[1] = prev->field_poc[1] + 2;
I find the error message is gone (only test videos that use frame coding
throughout).
