Interlaced video decoding with openh264dec

[Aniket Hande]

Hi,
I've been trying to decode an MPEG-2 TS stream using software decoding. The
stream codec is H.264. I'm using openh264dec to get frames for some other
purposes. However, I'm unable to get the decoder running. I checked and
found my source is interlaced and thus getting following in GST logs.

0:00:00.469505066  5691 0x55e3e03ccde0 WARN             openh264dec

Is there any way I can get openh264dec to decode my interlaced stream or is
my interpretation wrong here?
I'm using Gstreamer 1.16.
