Splitting Audio Extract (wav/flac) by Chapters
#1
Hi,
at first: great software, I was already able to extract DTS-HD files (and in the same run convert) them to multichannel flac/wav  Smile . (For Dolby TrueHD though decoding doesn't seem to work, probably due to some licencing issue/appropriate library missing - any advice on that?)

I have some conecert Blu-Rays and mkv-files from which I'd like to export multichannel audio files.
Is it possible to get separate audio files according to the video chapters i.e. split them by chapter marks while creating the output?

If not, maybe somebody has advice on an efficient workaround, I was thinking about somehow getting a cuesheet out of the source (mkvextract?) and split the audio file after exporting it out of the source using Hybrid.

Thanks in advance!

TrueHD decoding should work afaik., would need a sample to reproduce any problems you got.

You could try using "Base->Queue Chapters".

Wow, now that was quick.

According TrueHD - checked it again - it works. But for some reason exports to %TEMP%, therefore I dind't see it in the first place. Maybe some naming collision in the converting process, didn't get any clue out of the log file (Level 4) - but not really relevant for me either, I'll move the files from %TEMP% when finished. 

And chapter cutting also worked. It took me some time to realise that you are talking about a button Big Grin I was desperately scrolling through all options to find an option with the text written next to it.

Thank you!

I can probably fix that the output is saved into the temp instead of the output folder, but I would need a debug output level 9 of the whole job processing.

Hi Selur, as already mentioned, I'm perfectly fine with the result as it is; so no need to invest time in that from my point.
But I don't want to hinder you further improving your software so I attached the logfile Wink

Thanks for the debug output, will look into it.

Can't reproduce this atm.
What I did here is:
  • load an mkv source with trueHD audio
  • set 'Base->Processing->Video' to 'ignore'
  • set 'Base->Processing->Audio' to 'custom'
  • enable 'Audio->Base->Audio Enncoding Options'
  • set 'Audio->Base->Audio Enncoding Options->Encoder->Audio format' to 'flac'
  • set 'Audio->Base->Audio Enncoding Options->BPS' to '24'
  • press 'Audio->Base->Add current'
  • set an output with a '.raw' extension
  • created a new job (Base->Add to queue)
and I got the following subjobs:
Audio extraction: (output is saved to temp folder)
mkvextract tracks "F:\TestClips&Co\files\audio\trueHD Samples\hd_dolby_onyTHD.mkv" 1:"E:\Temp\iId_8_aid_0_20_51_19_1510_01.thd"
Audioconversion: (output is saved to output folder)
ffmpeg -y -threads 8 -loglevel fatal -i "E:\Temp\iId_8_aid_0_20_51_19_1510_01.thd" -ac 8 -ar 48000 -f sox - | sox --multi-threaded --ignore-length --temp "E:\Temp\20_51_19_151002" --buffer 524288 -S -t sox - --endian little -b 24 -t wav - | flac -f -F --ignore-chunk-sizes -5 -o "E:\Output\iId_8_aid_0_20_51_19_151002.flac" -
cleanup for "E:\Temp\iId_8_aid_0_20_51_19_1510_01.thd"
and a rename of "E:\Output\iId_8_aid_0_20_51_19_151002.flac" to "E:\Output\hd_dolby_onyTHD.flac"

-> Can you please describe in more detail what settings you are using?

Ps.: send you a link to a dev version via PM which might fix the issue (for flac)
