Integer overflow in the Q16 framerate calculation was sending
invalid values to the OMX encoder.
On the RPI4, this manifested as bitrate controls being ignored
on video streams with 6/1001 framerates. Video streams with
3/1001 framerates were not affected.

The single planar support was for NV21 only.
Add NV21 and YUV420P support.

This is a regression from 2562dd9e7831743ba6dc5680501fb7d26a2ec62c

On some Intel chips, sending VAEncMiscParameterTypeRateControl multiple
times causes the encoder to produce very low bitrates that do not match
the requested rate controls.
This is a regression as of af532c921575eb8ee805cc2c64a914f6302442e1. Prior

The hardware encoder on these chipsets produces very low bitrates
in VBR mode if it receives VAEncMiscParameterTypeRateControl more than once.

When using `ffprobe -show_format -show_streams -show_packets`,
it makes more sense to omit static data about the file format
and streams before the long list of packets instead of at the
end.

Previously the code assumed that stream_identifier was unique per stream
in the PMT, as suggested by the spec. However, I found some samples from
Finland MTV3 where this is not the case.
