e83f53dbed dcaparse: Expose block size in caps
This sets the "block_size" field on caps as the number of samples
encoded in one frame.

48e8c093dc dcaparse: Add depth and endianness to the caps
Some decoders can only handle specific endianness or a fixed
depth and this allows better negotiation.

Fixes bug #644208.

99baf8ae17 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.

3f683e0288 baseparse: Update min/max bitrate before first posting them
This avoids posting an initial min-bitrate of G_UINTMAX and max-bitrate
of 0.

cfc3f5e43b mpegaudioparse: Post CBR bitrate as nominal bitrate
Even if VBR headers are missing, we can't guarantee that a stream is in
fact a CBR stream, so it's safer to let baseparse calculate the average
bitrate rather than assume a CBR stream. However, in order to make
/some/ metadata available before the requisite number of frames have
been parsed, this posts the bitrate from the non-VBR headers as the
nominal bitrate.

7f805f17b2 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.

6a45c4f65e 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.

a6a982e8be 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.

aba0899b19 dcaparse: fix sync word for 14-bit little endian coding
Fix copy'n'paste bug that made us look for the raw little endian
sync word twice instead of looking for the 14-bit LE sync word

9b6439a36c 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.
