MPEG 1 Audio

[Xesdeeni]

DirectShowSource() reads the video only from an MPEG 1 file (including VCD .DAT), but not the audio. Is a plugin required to read the audio from the same file?

That's not possible. If you want to load the audio you need the plugin MPASource (see FAQ).

[Xesdeeni]

It looks like that plugin requires the audio be de-multiplexed from the video. Is it not possible to get the audio directly from the MPEG?

No, not yet. I hope that MPEGDecoder will be able to do that one of these days. Maybe you can beg Nic about that :)

LoL, I must have missed MPASource, if the codes open ill try & add it :)
(well actually what ill probably do is add demux code to mpasource and then let people use an return AudioDub(vid, aud) ;) )

Yup, one for AviSynth v2.07 and one for v2.5.

MPASOURCE:
It (only) uses the mpg123-Lib from the current LAME CVS.
The only challenge was to count the samples (which remebered me strongly on NIC's frame-counting problems).
But AFAIK AviSynth should get as precise counts as possible.
