DGIndexNV fails to demux LPCM off VOBs

Post by Boulder »

I have a DVD clip which I'm trying to index and demux the audio track while at it. The audio track is demuxed but it cannot be output or opened with AVISynth.

I extracted a few seconds off the beginning of the clip, and the issue is reproducable with it.

Works fine for me. Program stream PCM gets demuxed to WAV. The resulting WAV plays in MPC-HC. I don't know what you mean by "cannot be output". What audio source filter are you using with Avisynth and what is the error?

With WAVSource, I get the error that the file cannot be opened. MPC-HC cannot output it, just complains that I may be missing a codec. I can play the VOB and original VOB normally in MPC and the audio is just fine.

Again, I do not know what you mean by MPC-HC "cannot output it". You mean it cannot play it? I say again also that the demuxed WAV from your sample plays fine for me in MPC-HC.

Post your Avisynth script.

Maybe you should post your demuxed WAV so I can see if it is the same as mine.

This is what MPC tells me.

If I do eac3to "VTS_01_1 Ta0 48K 16bit 2ch.wav", it doesn't find anything wrong:
WAV, 2.0 channels, 16 bits, 1536kbps, 48kHz

If I do eac3to "VTS_01_1 Ta0 48K 16bit 2ch.wav" test.wav -normalize:
Reading WAV...
Original audio track: no audio data.
The WAV writer didn't receive the format information.
Aborted at file position 654380.

Here's the demuxed file:


The Avisynth script I've used is very simple at this point:

Code: Select all

video=DGSource("C:\Share\AV2010\av2010.dgi")
audio=WAVSource("C:\Share\AV2010\av2010 Ta0 48K 16bit 2ch.wav")
AudioDub(video, audio)

Please re-download slipstream 226 and try again. The WAV file was not being closed properly.
