Public bug reported:

Testing with the Big Buck Bunny videos (e.g. https://test-
videos.co.uk/vids/bigbuckbunny/mp4/h264/720/Big_Buck_Bunny_720_10s_10MB.mp4)

GST_DEBUG=*:1 totem Big_Buck_Bunny_720_10s_30MB.mp4

I see,

0:00:01.676017565 16373 0x5f89752c05e0 ERROR            openh264dec
:0::<openh264dec0> [OpenH264] this = 0x0x7f09e001a000, Error:Ref Picture
for B-Slice is lost, B-Slice decoding cannot be continued!

Even with gst-plugins-bad installed. There are two problems here.

1. openh264dec is ranked more highly than libav decoders for h264 (on
jammy at least). That's a suboptimal user experience, since openh264dec
is not as robust

2. Totem stalls out after about 1 second with no guidance to the user
what went wrong.
