Right now, all input stream side data (save for CPB) is copied to the output stream. Without this chunk, the frame cropping side data will be copied regardless of it having been applied or not at the decoding level. I don't know how else to prevent that. Maybe removing the side data from the input stream? Although that's pretty ugly.
I have a separate patchset adding packet side data to codecpar and avctx, and deprecating AVStream.side_data in favor of it. With that, i could maybe use and therefore remove the cropping side data from ist->par (which is internal to the CLI) if applied.
I know the code below already does the same thing, but I'd like to get rid of it rather than add to it.
