6d78d32d51 baseparse: estimate duration on EOS
For files which are smaller than 1.5 seconds, the duration
estimation does not happen. So the duration will always be
displayed as 0. Updating the duration on EOS when the estimation
has not happened already

ea8cabe084 baseparse: put buffer in a correct state after gst_adapter_get_buffer call
We must make the buffer writable to write its PTS and DTS, and also
reset its duration.

The behaviour is now the same as before commit c3bcbadd, except metas
might still be attached to the buffer extracted from the adapter.

c3bcbadd54 baseparse: Use new gst_adapter_get_buffer() API instead of gst_adapter_map()
This preserves GstMeta properly unless the subclass does special things. It's
enough to make h264parse's stream-format/alignment conversion pass through
metas as needed.

b58245ac0a baseparse: fix GST_BASE_PARSE_FLAG_LOST_SYNC
Since frame->priv->discont was cleared earlier,
GST_BASE_PARSE_FLAG_LOST_SYNC was never being set.

Take the chance to refactor the frame creation a bit to
organize the flags setting and reset.

a041d8862d baseparse: only post 'no valid frames' error if buffers were received
Otherwise baseparse will consider empty streams to be an error while
an empty stream is a valid scenario. With this patch, errors would
only be emitted if the parser received data but wasn't able to
produce any output from it.

This change is only for push-mode operation as in pull mode an
empty file can be considered an error for the one driving the
pipeline

Includes a unit test for it

780f71c4d5 baseparse: reset skip on segments and discontinuities
Large scale skip is an optimization, and thus it is safer to
stop skipping than to continue. Clear skip on segments and
discontinuities, as these are points where it is possible that
the original idea of "bytes to skip" changes.

59c34a8ff7 baseparse: handle streamheaders by prepending them to the stream
Add a first_buffer boolean state flag to have baseparse do actions
before pushing data. This is used to check the caps for streamheader
buffers that are prepended to the stream, but only if the first buffer
isn't already marked with the _HEADER flag. In this case, it is assumed
that the _HEADER marked buffer is the same as the streamheader.

4c38895f4b baseparse: Return FLOW_FLUSHING when pushing a frame on a pad that has been flushed
When going to READY, it is possible that we are still pusing a frame but that
our srcpad has already been set to flushing. In that case we should not
post any error on the bus but instead cleanly return FLOW_FLUSHING.

b7516dbf7c baseparse: avoid returning _OK for _NOT_LINKED
When the parser receives non-aligned packets it can push a buffer
and get a not-linked return while still leaving some data still to
be parsed. This remaining data will not form a complete frame and
the subclass likely returns _OK and baseparse would take that
as the return, while it the element is actually not-linked.

This patch fixes this by storing the last flow-return from a push
and using that if a parsing operation doesn't result in data being
flushed or skipped.

a76db74496 baseparse: Fix splitting and reversing of GOPs in reverse playback mode
We iterate the current discont group backwards and push each GOP forwards,
starting from the last one. However if the first buffer in the current
discont group is a keyframe, we will keep it around until next time,
which is far from ideal. Just push it.

a3ff2976cc baseparse: do not accumulate buffers on passthrough mode
If on passthrough during reverse playback, do not accumulate buffers as
baseparse will never check for DISCONT flag to push those buffers.

51fa54a281 baseparse: do not ignore TIME segments
TIME segments are being ignored and a standard initialized
segment is used instead. This causes issues as not properly detecting
reverse playback or not cliping output based on the segment.

e02c00a58a baseparse: remove pending_segment as it was being misused
It wasn't required, instead baseparse was using it to check the media

The pending_segment was removed and a checked_media boolean
replaced it for a more accurate naming.

accaadf52a baseparse: push pending events before GAP event
A GAP event is handled as an empty buffer by sinks and they expect
to receive start up events before GAP events (like a segment).

This is important specially if there is a GAP at the beginning of
a stream (before any buffers) so that the segment event can be
pushed downstream before the GAP

This property simply ignores requests from the element to enable passthrough
