d17d6d74be audioparsers: not so greedy minimum frame size
... which will be determined by parsing anyway, and avoids introducing
redundant additional latency.

a53540346a flacparse: tell baseparse the duration in samples for better accuracy
Tell GstBaseParse the duration in samples instead of time, so that
a duration query in DEFAULT format will return the correct number
of samples without rounding errors. Baseparse will convert this
into time itself when needed.

e0cadab5c2 flacparse: don't error out on invalid minimum_blocksize value in streaminfo header
We don't use it, so may just as well accept an invalid value
of 0 here, which is likely inconsequential anyway.

bf9859ad61 dcaparse: Add depth and endianness to the caps

f3f44f81c3 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.

7f4a61b56c 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.

551eefb757 baseparse: refactor passthrough into format flags
Also add a format flag to signal baseparse that subclass/format can provide
