MeGUI encoding to AAC and other - Inner exception: null problem??

[Undead Sega]

I dont know fi any others have been getting this problem but this kind of new to me and i cant see what could be the problem.

i am just basically taking an AAC file to downmix it to AAC or ven to AC3 or MP3 and i always get this kind of log with it ending with Inner exception: null:

i have Avisynth 2.5, all the latest updates on MeGUI, and strangely the MP4 that this contained doesnt open up in something simple as TMPEG Xpress which usually loads up. can anyone help me on this?

You're probably missing a directshow aac source filter

Are you feeding the aac directly? Can you render the aac in graphstudio?

Instead of installing one, another option is to feed the aac in mp4 , and if you have a directshow mp4 splitter installed it should work

[Undead Sega]

i am feeling the aac directly to MeGUI, but i do have ffdshow of course, is that what i needed? or is it something else may i ask?

[poisondeathray]

No, your directshow filter chain is probably broken (pins don't connect). Render it in graphedit / graphstudio and you will see what I mean

You probably don't have a directshow mp4 splitter installed, that's why it doesn't work in the mp4 container either

You can install DCBassSource.ax for example, as an AAC directshow source filter (register it with radlight filter manager)

[Undead Sega]

ohh i see, well i will graphedit very soon, however ive just imported the MP4 file itself into MeGUI and right now it seems tob e Pre-processing, im hoping it will work.

but i really would prefer it if i could hve taken the file directly which is actually my problem. THus where can i get DCBassSource.ax? and where do i install it? is there somesort of package i need to download and install?

you can register it with radlight filter manager

if it works with the mp4 , then your directshow filter chain for mp4 must be working correctly

Hi, sorry for bringing this up again, but i really appreciated the help u were obtaining me, but if u say that the directshow filter is working correctly, then why is it still i cannot input the audio files directly?

also, one of the main reasons ive brought this back up, is because ive encountered another problem, and this is from inputting the mp4 file (that contains an AC3 source i want to transcode to AAC) i get an error called: RenderFile, the filter graph manager won't talk to me

i am confused at this part here, i dont understand why this is happening, can anyone help me on this?

yes, working for aac in mp4 container, but you still need a source filter to use aac audio directly as already mentioned.

For your second problem, you need a directshow mp4 splitter that accepts ac3 in mp4. You can register the one from here which works, or the one from MPCHC project as a standalone filter

http://sourceforge.net/projects/guliverkli2/files/DirectShow%20Filters/#

Another option is to use a different script and forget about directshow filters eg. ffms2
FFMpegSource2("video.mp4", atrack=-1)
