Summary of the bug: A HEVC broadcast video stream encoded by the Makito
encoder configured to use HEVC 1920×1080i video is identified as
1920×540p.
How to reproduce: The following captures were provided to us by the
broadcaster, and I have been given permission to share them for the
purpose of this bug report. They were created by the Makito encoder
software:
* [https://www.dropbox.com/scl/fi/77pmthkf3uv3zf3a4yjfk/hevc-
interlace-1.ts?rlkey=ray5xnepc2lwuzzomccujiaqf&dl=1 Sample 1]
* [https://www.dropbox.com/scl/fi/oqag1b7f8t8lqettjolst/hevc-
interlace-2.ts?rlkey=pp1wah7ep32pbx355tcbszb7v&dl=1 Sample 2]
Running ffprobe on the samples detects them as 1920×540p with a 32:9 DAR,
and playing them with ffplay do display them in 32:9.

When feeding frames directly to the codec, it does look like the
AV_FRAME_FLAG_INTERLACED bit is set correctly in the returned frame.
According to the provider of the sample, the Makito encoder (the version
number was not indicated) is configured as follows:
* Codec Algorithm: HEVC/H.265
* Resolution: 1920×1080i
* GOP Size: 60
* Encoding Profile: Main 10
* Resizing: Scale
* Closed Captioning: on
* Chroma Subsampling: 4:2:0 10-bit
* Frame Rate: Automatic
* Transcode Source: System
* Rate Control: CBR
* Framing: IBBBBP
* Counting Mode: UTC Conversion
* Bitrate: 6000
* Aspect Ratio: Automatic
* Scene Change Detection: off
* Partial Image Skip: on
* Intra Refresh: off
