CTS-based seek is reasonable since player requests frames in output order
not coded order.

This change fixes seek to a keyframe within consecutive keyframes.
Let's say P[0|-1] and P[1|0], here x and y inside [x|y] are PTS and DTS
respectively, and both two frames are a keyframe. If you try to seek on
PTS=0, i.e. P[0|-1], you'll get P[1|0] if the demuxer is DTS based. This
is obviously undesirable.

inside it a rectangle filling the whole window to highlight it.

The segment field in the struct has to be conditionally build
as well.

It is required.

Also, move a misplaced block to the right position.

This is not an API change; the fields were explicitly declared private
before.

analyze() is currently called both when probing and from read_header().
It determines the packet start by looking for the sync byte, followed by
unset Transport Error Indicator and valid adaptation_field_control.

This makes sense to do when probing, but once we already know the format
is MPEG-TS, it is counterproductive to be so strict -- e.g. in some
files the TEI might be set and analyze() might get called with a smaller
buffer than the one used for probing, resulting in a failure.

Nothing uses it, and it provides no public API.

Archeological finds:

Commit 101036ad added the API.
Commit a8dd8dc6 made mpegts.c use it.
Commit af8aae3f disabled it by default in mpegts.c.
Commit ae2bb52c removed all uses of this from mpegts.c.

The source is er_eld_2100np_48_ep0.mp4 from the official test set.

Some files contain a few additional, all-0 bits.
Check for that case and don't print incorrect "not supported"
