BeSweet with Aften on long 5.1 files

[Nick]

I am trying to get 5.1 AC3 audio from NTSC to PAL using BeSweet, calling Aften via bsn.dll

Example commandline

BeSweet.exe -core( -input C:\temp\Extracted_audio_1.ac3 -output C:\temp\Encoded_audio_1.ac3 -logfile C:\temp\Encoded_audio_1.log ) -azid( -c normal -g max ) -ota( -r 23976 25000 ) -bsn( -exe aften.exe -b 384 -6chnew -readtoeof 1)

Essentially, this commandline is generated by DVD2SVCD using 2lame for mp2 encoding. I have written a simple batch file to parse the command line and run Besweet, substituting the 2lame parameters for bsn/Aften parameters, thus getting AC3 output.

This works fine for small files but Besweet either hangs without -readtoeof 1, or exits with it at the 2h 04m mark. I have seen others with similar problems but the solutions tended to either involve an intermediate wav file, which I am keen to avoid, or GUI applications where I need commandline.

Is there any easy way to overcome this limitation of the technique I use or are there any other simple ways to achieve this conversion as a "one application" event?

Thanks in advance to anyone who may be able to help.

Yes, by updating your bsn (http://kurtnoise.free.fr/index.php?dir=BeLight/&file=bsn_20070513.zip) lib...:)

Ah. Looked for an update but couldn't find one.
Your site was misbehaving earlier - getting "couldn't find server at..." and 404 errors. It's fine now, though.

And thanks for the update - it works a treat.

@Kurtnoise, only you can do this solution.

But for me -ota( -r 23967 25000 ) don't work at all, even for stereo and little files, always:

And soundtouch only work for stereo.

@Nick, maybe you can use Bepipe-AviSynth with your decoder:
bepipe --script "NicAc3Source(^C:\temp\your.ac3^, DRC=1).TimeStretch(tempo=104.2709).Normalize()" | Aften -b 384 -readtoeof 1 - "C:\temp\encoded.ac3"

Bepipe need .NET Framework 2.0, to avoid this dependence we can use the AviSynth plugin SoundOut (http://forum.doom9.org/showthread.php?t=120025)

Wrong frameRate ? Shouldn't be 23976 instead ? coz it works fine here...

Thanks Kurtnoise, my typo fault. Work fine with -ota( -r 23976 25000 ).

BTW, I never see in ota docs the values must be exactly the standards NTSC and PAL.
