avenc_mpeg2video caps?

[Jordan Johnson]

Got the chroma format working, but now I have an issue with the vbv buffer.
And the PTS issue still persists. Using a PS/TS mux didn't help either.
Here is my current line. Renders fine, but those PTS and vbv errors make it
not work in my application.

*gst-launch-1.0 -v videotestsrc ! 'video/x-raw, pixel-aspect-ratio=1/1,
interlace-mode=progressive, width=1920, height=1080, framerate=30/1' !
queue ! videoconvert ! video/x-raw,format=I420 ! avenc_mpeg2video
bitrate=17000 buffer-size=240 gop-size=25 max-bframes=2 me-sub-cmp=2
mb-cmp=2 ! queue ! filesink location=test.mpeg*
