Open AAC With AviSynth

[koberulz]

Is this possible? I tried DirectShowSource(), which works for ac3, but get a 'specified module could not be found' if I try with an AAC file.

Make sure the AAC checkbox is ticked in LAV Splitter's configuration window.

Or use L-Smash ( lsmashaudiosource() in case of mp4/m4a, lwlibavaudiosource() works always) or ffms2 ( ffaudiosource() ).

[koberulz]

Or use L-Smash ( lsmashaudiosource()

"The number of tracks equals 0".

lwlibavaudiosource()

"CAVIStreamSynth: System exception - Access Violation at 0x32d1e08, writing to 0xe46e3a0"

ffms2 ( ffaudiosource() ).

"No function named FFAudioSource".


EDIT: And having downloaded and installed LAV Splitter, DirectShowSource() now causes MPC to just crash completely.

"CAVIStreamSynth: System exception - Access Violation at 0x32d1e08, writing to 0xe46e3a0"

lwlibavaudiosource() will try to write an index file. Is the folder you are operating in write protected? Try different folder or manually set a different index location or set cache=false to disable completely.

"No function named FFAudioSource".

Like L-Smash it's not included in the standard AviSynth package: https://github.com/FFMS/ffms2/releases

[koberulz]

Yes, turns out it was read-only for some reason. But MPC is still crashing when I try to preview, installing LAV Splitter has completely broken it.

EDIT: Uninstalled LAV, changed folder permissions, and set cache to false. Still getting the error.

EDIT: Downloaded ffms2, not sure how to install?

try FFdshow, works with me.

LAV is the standard splitter that comes with MPC-HC. In my experience it rarely, if ever, crashes. If it crashes with the latest versions you should contact the developers or at least upload the sample file here for others to do it. Note that LAV isn't always used by default in all DirectShow applications. There's the splitters, the video and audio decoders and merits might need to be increased. That's one of the reasons many people prefer l-smash/ffms2 in AviSynth.

[koberulz]

FFdshow is installed and set up as in that screenshot. Is there a different script I should be using for that?

It was working fine, I installed LAV, it crashed every time I tried anything that had worked before, I uninstalled LAV, it worked fine again.

[ricardouk]

Using the following aac sample:
http://cdn.online-convert.com/example-file/audio/example.aac

with

DirectShowSource("example.aac")

plays fine here, when i play the avs in mpc-hc the haali media spliter icon shows up in the system tray/notification area....try to install haali

[koberulz]

Haali is installed.

[ricardouk]

run Win7DSFilterTweaker, shows us what it says about aac

[koberulz]

I'm running Vista, does that still apply?

[ricardouk]

try it, never used Vista. See what it displays about aac...

[koberulz]

Can't, I just get an error saying it doesn't support my version of Windows.

perhaps someone with more experience can help you, have you instaled codec packs? in the meantime try the microsoft codec utility fix:
