BeHappy - AviSynth based audio transcoding tool (UPD 19-07-2006) - Page 18

Robot · 18th July 2006, 11:27

I re-installed Avisynth and restarted. I get the same error. I exported the script.

Wich OS did You use?
Are you able to play obtained script via mplayerc?

How is that possible?

It's an aac-file, not an avs-file...
Try to use DierectShowSource or BassAudio, then it should work properly.

I use Windows XP

and I have no idea what the next thing means.
I'm a novice.

In BeHappy [1] Source you must select DirectShowSource instead AviSynth after the input file.

And don't forget about AAC splitter

I'm lost. No matter what I do, I get this error:

Can somebody compile this app into one package with all plugins etc. I don't even know where to begin, everything is all over the place.

thuongshoo · 19th July 2006, 06:54

@nfm : I often install K-lite codec pack , and plugin which is need for Behappy is at gotdotnet

Ok, will be fixed tonight

Is there a way to run BeHappy with commandline parameters or run FFmpeg with AviSynth without Behappy?

Don't get me wrong, Behappy does exacty what I need, but I'm creating a frontend for AVI to DVD and FFmpeg can't encode 5.1 channels correctly just by itself. If I have to use BeHappy to do the work, then it's going to take tons of 'SendKeys' to control it.

I thought I had figured it out with FFmpeg, but I don't. If I encode 5.1 channel 448kbps AC3 to 5.1 channel 384kbps AC3, then the center channel is moved to the front right channel.

What is BeHappy exactly doing to keep all the channels correct? I know it's using FFmpeg and AviSynth, but how is FFmpeg executed with the script to keep the channels in the correct place?

This is the AviSynth script Behappy gives me.

Code:

NicAc3Source("D:\TestAudio.ac3")
6==Audiochannels(last)?GetChannel(last,1,3,2,5,6,4):last

First line decode the ac3 to wav in correct wav order (L,R,C,LFE,SL,SR).

Last line, if there are 6 channels, re-order the channels from (L,R,C,LFE,SL,SR) to (L,C,R,SL,SR,LFE)

You can use Bepipe instead BeHappy with this command line:

Code:

Bepipe --script "NicAc3Source(^D:\TestAudio.ac3^).GetChannel(1,3,2,5,6,4)" | ffmpeg  -i - -y -acodec ac3 -ab 384 "D:\TestAudioEncoded.ac3"

Or with new Aften encoder

Code:

Bepipe --script "NicAc3Source(^D:\TestAudio.ac3^)" | Aften -b 384000 - "D:\TestAudioEncoded.ac3"

That works great!

Thank you very much, tebasuna51

Dimzon, Thanks in advance.

@Tebasuna
Valid values in what sense? Regarding Dolby specs? or non-compliant for soft players? SAP players?
I would like to DRC/Normalize AC3-6ch with a lower bitrate than original; ie: 352 or 288 ...actually limited to 320 or 256 with ffmpeg ...?
Thanks for the info.

tebasuna51 · 22nd July 2006, 21:07

@BigDid, bitrate must be discrete values, see 5.4.1.4 frmsizecod and Table 5.18 at: ATSC Standard: Digital Audio Compression (AC-3), Revision A

Edit: Each ac3 frame (32 msec. if 48 KHz) must have a discrete value, the VBR method is obtained with different bitrate frames. This method is not well supported.

So it's in the specs.

I'll try to reformulate: Not being a "discrete value"(aka one one the supported bitrate from the specs) a Vbr resulting ac3 stream should not be well supported ...
Is it correct?
BTW I was speaking of CBR, not VBR but I suppose same conclusions applies.
Sorry to be dumb but I am not so... performant in audio matters

Thanks.

I was wondering if anyone has achieved good results when converting from 6ch AAC to 6ch AC3 using BeHappy?

I converted my AAC file to a 6ch WAV file using audio2wav. Right now, I'm pondering whether I should add BeHappy's Digital Signal Processing. If I keep to the original, it won't change a thing and directly convert that to AC3 am I right?

Without problems using DirectShowSource and ffdshow Audio decoder properly configured.

I don't understand your question.
If you use faad decoder (audio2wav) the 6ch wav (with WAVE_FORMAT_EXTENSIBLE header) can be converted directly to ac3 with Aften encoder.
If you want open the 6ch wav in BeHappy you need BassAudio
because WAVE_FORMAT_EXTENSIBLE header.
