Nowhere as far as I can tell.
No matter where you place it, it seems codec->flags is only ever set
on input_streams, never on output_streams, no matter in how many
places you put the flag.
The only difference is that with re-encode the output codec settings
get completely overwritten with the input values, so unless I have
no clue how the FFmpeg command-line works (quite likely) that's rather
two bugs having a party than something working properly.
