551eefb757 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.

32f57133ac baseparse: allow increasing min_size for current frame parsing only 
Also check that subclass actually either directs to skip bytes or
increases expected frame size to avoid going nowhere in bogus
indefinite looping.

244f747df2 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.

bb8f0d3b4c 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
as well. Fixes parsing of such streams (see #636234 for sample file).

... which is not particular relevant for audio parsing, but more so
in video cases.  In particular, auto-determine if dealing with video (caps).

a45019fdd6 baseparse: use correct offset when adding index entry 
... bearing in mind that BUFFER_OFFSET is media specific and may not
reflect the basic offset after having been parsed.

76b322a429 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.

75735c4573 audioparsers: add very basic dts/dca parser

processing already-chunked input (created with matroskademux ! gdppay).
