AVS plus 5.1 audio channels to WMV

[buzzqw]

Hi all !

i had successfully implemented the wvc1 encoder into automkv but i have a problem with audio

my application work through avisynth both for video and audio.

a typical avs look like

movie = mpeg2source("movie.d2v")
audio = NicAC3Source("audio.ac3")
movie=lanczosresize(movie,640,480)
return audiodub(audio,movie)

in this way the audio will be 5.1 and the wmcmd.vbs parameter are (for audio, i cut out the video part):
-a_codec wmapro -a_mode 0 -a_setting 192_48_6

in this way the cscript.exe goes crazy and crash.

BUT if downmix (either with NicAC3Source("audio.ac3",2) or by adding audio=getchannel(audio,1,2) the encoding goes fine without a problem (same command line but 192_48_2).

i tryed even with directshowsource (using ffdshow as decoder) but the problem is the same

Any tips ?

Surely you mean -a_setting 192_48_6_24, right? 192_48_6 is not a valid setting.

[buzzqw]

the _24 could be omitted... since is default ?

and anyway with or without for me isn't working... cscript (ver 5.6) crash (tryed with directshowsource (ffdshow) and with NicAC3Source)

i tryed even with 1 pass encoding, no way
i tryed with makeavis (from ffdshow package), now way

other suggestion ?

thanks for your interest !

Perhaps the 6ch output is not in a format that WME9 expects. For example, WAVE_FORMAT_IEEE_FLOAT output support was only added in Avisynth 2.57.

[buzzqw]

ok, got it, thanks.

in that case i need to process multichannel with directshowsource or even the nicac3source is enough ?

I believe WME9 is expecting this audio media type when using 6ch or 8ch audio from an AVI file:

Is this what you're getting out of Avisynth? You can verify by playing it back in Media Player Classic and checking the pin properties of the audio renderer input pin.

ok, i had installed avisynth 17/09 build and also update directshowsource.dll to latest beta

my pin is

ffdshow is used as decoder

the script: i tryed both nicac3source and directshowsource (both on ac3 and vob file)

with this script
movie = mpeg2source("movie.d2v")
audio = NicAC3Source("audio.ac3")
OPT_AllowFloatAudio=True
return audiodub(audio,movie)
cscript crash
if i substitute the

audio = NicAC3Source("audio.ac3")
with
audio=directshowsource("audio.ac3")
crash again

NOTE both script play nicely on windows media player

even this scrip
movie=directshowsource("test.vob",audio=false)
audio=directshowsource("test.vob",video=false)
cause a crash

this is the paramenter of audio encoding
-a_codec wmapro -a_mode 0 -a_setting 192_48_6_16 or _24 don't change a thing...
while encoding in -v_mode 0 (cbr with wvc1)

on last even this simple script
directshowsource("test.vob")
crash... :(

i will be glad to be of any support to resolve the problem

Does the crash happen if you disable ffdshow as audio decoder? You shouldn't need an audio decoder for PCM audio.

If you have Visual Studio installed, could you run this under a debugger and get a call stack on the crash?

[buzzqw]

if i disable in ffdshow (audio part) "Uncompressed" (the latest one in list) i am UNABLE to play those avs

... and i am unable to "Debug"... my knowledge of programming are quite limited :(

Can Visual Studio Beta 1 load an Avs file that has the video and audio dubbed

Can Visual Studio Beta 1 load an Avs file that has the video and audio dubbed
I'm not sure I understand your question. What is this related to?

[buzzqw]

@Can Visual Studio Beta 1 load an Avs file that has the video and audio dubbed

for me is only crash on wmse

movie=mpeg2source(movie.d2v")
#audio = nicac3source("fixed1.ac3") #result don't change using nicac3source
audio = directshowsource("fixed1.ac3")

audio=ConvertAudioTo32bit(audio) #tested with or without
OPT_AllowFloatAudio=True #tested with or without
return audiodub(audio,movie) # @Zambelli this mean dubbed

Sounds like somebody made a leap from Visual Studio to WME Studio Edition. Talk about a non-sequitur. ;)

[buzzqw]

ops... my brain had translate visual studio to wmse.. sorry

but i doubt that a RAD could load a avs... :p

I have a request for Microsoft/Zambelli: is possible to have an "normal" audio encoder (.exe) that accept piping as NeroAACEnc.exe ?

the same could be done with Windows Media Video, for not using cscript.exe/WMCmd.vbs ?

EDIT: obviusly must be possible to mux audio and video...

thanks a lots
