Hallo,
habe gerade die neue Verion 0.80 des bitstreamout plugins
hochgeladen. Aus dem Changelog:
- Add nonlinear mp2 loop through S/P-DIF similar to AC3/DTS
- Use a frame based mp2 parser for libmad with buffer gard
- Make PCM initial wait frames configurable
- Remove Z680 option
- Remove MP2offset
- Add a workaround for broken sub audio header in PS1 payloads
- Be smarter in AV synchronization, wait on stable STC value
- Make xlist find plain AC3 in PS1 payload even from ORF

Mp2Out (Round,Dither,Nonlinear)
Switch for the configuration how to use the MP2 Audio input
stream from VDR at replaying a recording or during live viewing
from DVB card.
The two cases Round and Dither are switches for the resulting
linear PCM which its self will be obtained by decoding the MP2
Audio input stream with the help of the LibMad. Dithering leads
to a much better sound quality then Rounding it does.
The Nonlinear option provides an alternative way how to put MP2
Audio data forward to the A/V receiver. With this the MP2 Audio
will not be decoded but send with a simliar method as done for
AC-3 or DTS input streams. If and only if your A/V receiver
supports the decoding of MP2 Audio stream you may choose this
option. But note that for daily use your A/V receiver should
support automatic detection of MP2 Audio. Or you have to con-
figure your A/V receiver by hand for every change between AC-3,
DTS and MP2 Audio input sources.

Und gleich noch Ausschnitt aus der manual page über die
``PCM initial wait frames``:
[...]
PCMinitial [1...12]
The numbers of initial PCM wait frames to reset the parser and
decoder of your A/V receiver at LiveTV. As larger the number as
more your A/V receiver can synchronize but only up to the maxi-
mal filling grade of its input buffer. If the value is to large
you will hear a large silent pause. You should then decrease the
value. A good value for, e.g. Pioneer VSA-E07 is 6. Small val-
ues may cause an underrun of the hardware buffer of your sound-
card, which can be heard as a short staccato or reset (see Vari-
ableIO) initial after a channel switch.
