Hi,
I've uploaded the new verion 0.80 of the bitstreamout plugin.
From the changelog from this morning:
- 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
A note about nonlinear mp2 loop through also from the manual page:
[...]
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.

A further note from the manual page about the 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.
