In the case pps_subpic_less_than_one_tile_slice is called, the
subpicture is smaller than the tile and so there are multiple
subpictures in the tile. Of course, then, not all the
subpictures can start in the top-left corner as the code before the
patch does. Patch fixes this

Previously, VUI information was not exposed.
If the container lacks HDR metadata, HDR videos appear washed out

AVCodecContext->sw_pix_fmt is used to hold the software pixel format.

Hi Zhili,
Thank you for v2,

Nit: The if statement is too long. Move it after generate_missing_ref and
break it up to simplify the logic.
like:
if (!ref) {
ref = generate_missing_ref(s, fc, poc);
if (!ref)
return AVERROR(ENOMEM);
}

Thank you for the patch.
This will fail on GDR clips, such as:
GDR_B_NOKIA_2.bit
GDR_C_NOKIA_2.bit
By design, a GDR frame refers to missing frames and gradually ref
