But only add this for non-live playlists. For live playlists we already
have another thread that is periodically updating playlists.
Reason for this is that sometimes downloading a fragment can fail because
the URIs have changed or expired since last time.
Sequence numbers in different playlists are not guaranteed to be the same for the
same position, e.g. fragments could have different durations in different playlists.
In theory we should do exactly the same for live playlists, but unfortunately we can't
because doing this kind of seeking requires the complete playlist since we started
playback. For live playlists the server is however dropping fragments in the beginning
over time and we have no absolute time references.
The tag was dereferenced earier. From the libschroedinger code,
it's not obvious to see whether tag and frame would be NULL at
the same time. I think is likely that both will be non NULL
here, but that's not certain. Additional tests may be needed
to avoid dereferencing tag and/or frame, but what to do if
only one is NULL isn't obvious, as the _get_tag function does
transfer ownership so isn't undoable.

It was originally test for 9 bytes (as the comment says) and was
rewritten buggily. So rewrite it a third way, which is now
hopefully consistent with the original and the comment, while
being more sense-making to humans.

Turns out glib aborts on allocation failure, so this is pointless.
We'll just ignore Coverity warnings on such constructs.
This reverts commit d347809a82.
So this is actually pointless. We'll just have to ignore
Coverity moaning on those.
Revert "mpegts: test for allocation failure"
This reverts commit 224cb81b8f.
While it's unlikely to get there, it silences the coverity warning
on the error code path that we test for NULL before freeing, when
all branches there are from locations where pmt cannot be NULL,
and removing the NULL check makes the code more vulnerable to a
hypothetical future branch from somewhere where it can be.

When we'd see an unknown stream type, then a SDDS stream.
Then we'd get to the end of the switch with a NULL temp stream
pointer, and dereference it.

While this probably should never happen if callers are well behaved,
this avoids a crash if it does. With a warning about it. Unsure if
it'd be better to not add at all, but it should not happen...

While it will probably not trigger, it should silence a Coverity
warning about the fail code path testing for NULLness before
freeing, where the buffer was already dereferenced. It seems
safest to keep that test, in case future goto fail statements
happen to have a NULL buffer there.

While the code that creates the object sets priv to some existing
pointer after new, this ensures any future new not doing this will
hit the various priv!=NULL asserts in the code.

Recent refactoring causes this code to be called with either a NULL
fragment, or a non NULL fragment. In the former case, we don't have
a buffer. In the latter case, the original code dealing with DISCONT
assumed the buffer was valid. Testing for a NULL buffer here thus
does not seem to change the intent, and fixes:
