MPASource: direct MP1 MP2 MP3 reading

[cweb]

Hi

mpaSource("all MPA T01 DELAY 0ms.mpa", normalize = true).BufferAudio()

gives me blank audio. The source file is dvb-s, 48khz 192kbs.
I had to change it to normalize=false to get sound with the actual audio.

Thanks for a great plugin by the way!

Please use
- latest AviSynth
- float mpasource
- NO bufferaudio (it's already built-in in AviSynth)

Does it then work with normalize and can you post the content of the .d2a file (please delete it first!) ?

New version:
- without mpeg1 Layer1 support (ID3 tags were misidentified as Layer1)
- global variables removed which prohibited to use it more than once in a script reliably
- EXIT on some rare stream errors removed which could close the application
- some bugfixes from the mpg123-lib of the LAME project which were made after mpasource.

A bug is introduced in this version, when use 'pipe' commands like:

Bepipe --script "MPASource(^sample.mp2^)" | neroaacenc -if - -of sample.mp4 -q 0.5

the audio data is corrupted by text messages like:

MPEG 1.0 layer II, 384 kbit/s, 48000 Hz stereo

The problem is in the mpg123/common.c:

In old version is correct with 'stderr'.
