Tim-Philipp Müller de16d5adb3 baseparse: rename GstBaseFormat to GstBaseFormatFlags and fix up associated API 
Also change gst_base_parse_set_format(parse,flags,switch_on) to
gst_base_parse_set_format_flags(parse,flags) which is more in line
with the rest of our API and how the function is used.

Tim-Philipp Müller f691be223e baseparse: don't expose GstAdapter in public header 
None of the existing subclasses needs access to that, so there's
no reason to expose it for now.

Tim-Philipp Müller e2bf3647f8 baseparse: move various segment-related members into the private instance struct 
If none of the existing subclasses uses these, there's probably no
need to expose them at the moment. Keep the segment itself exposed
though.

Mark Nauwelaerts 3882b7f2ed baseparse: tune QUERY_SEEKING response 
Even if we currently do not have a duration yet, assume seekable if
it looks like we'll likely be able to determine it later on
(which coincides with needed information to perform seeking).

Fixes #641047.

Arun Raghavan 694d5c4b75 baseparse: Update min/max bitrate before first posting them

of 0.

Mark Nauwelaerts ae23eb9955 baseparse: tune default duration estimate update interval 
Rather than a fixed default frame count, estimate frame count to aim for
an interval duration depending on fps if available, otherwise use old
fixed default.

Mark Nauwelaerts c38fbf8879 baseparse: refactor passthrough into format flags 
Also add a format flag to signal baseparse that subclass/format can provide
(parsed) timestamp rather than an estimated one.  In particular, such "strong"
timestamp then allows to e.g. determine duration.

increases expected frame size to avoid going nowhere in bogus
indefinite looping.

Thiago Santos a3e55038ac audioparsers: baseparse: Be careful to not lose the event ref 
Don't unref the event if it hasn't been handled, because the caller
assumes it is still valid and might reuse it.

I ran into this problem when transcoding an AVI (with mp3 inside)
to gpp.

Mark Nauwelaerts 3faccbd29f baseparse: enhancements for timestamp marked framed formats 
That is, as such formats allow subclass to extract position from frame,
it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.

Fixes #631389.
