Streaming SACD ISOs

[jacobacci]

Hi Simon

I hope you are doing well and staying safe in these turbulent times.
I have more than 2'000 SACD ISOs in my music collection and they are quite a pain. To browse and play them I need jRiver. The dCS Mosaic app which I normally use to control my dCS Rossini DAC is best used with a DLNA Server and for me it happens to be Minimserver for many years. THANKS for a great product.

With regard to playing SACD ISOs, there seem to be several possibilities:

• play them using jRiver, which is a pain and does not work well over ethernet (i.e. no gapless)
• extract DSF files from all of them, which would solve the issue for good, but is a monumental tasks (just did 10 yesterday and that was quite a piece of work)
• find a DLNA Server which can deal with SACD ISOs
  

The last possibility seems like a no go at first sight, but I think there might be hope. Just as you use ffmpeg to transcode in Minimserver, might it be possible to use sacd_extract to do the same for ISOs?

I have looked at sacd_extract a bit and it seems there are two functionalities that could enable something like this:

• sacd_extract can extract just the metadata from an ISO. This is a very fast process and should yield all the information needed to display the content of an ISO. I have attached sacd.txt, which is an example of such an output, that could certainly be parsed to deliver the usual metadata
• Once a play command is issued for a track, that track could be extracted on the fly and sent to the DAC just like normal files
  

Do you think something like this might be doable? I am fully aware that such a scheme would not have the usual user interface comfort, but it would suffice to make ISOs streamable to the many users out there who have a significant number of them.

Thanks and best regards
Rudi
