Asset UPnP for Raspberry pi

Re: Asset UPnP for Raspberry pi

Yes, with the CIFS Read Buffer at the max 16M, there can be some Naim buffer exhaustion and dropout at the end of playing a transcoded 24/192 track when the ND5 makes the request to 'Get' the next track in the playlist, to ensure that there is 'Gapless' playback. This happens about 30s-40s before the end of the current track. The RPi is still processing the current buffer with the current track. So I have gone back to the default CIFS Read buffer size and everything plays fine during the track and at the end. Obviously there is more of a continuous stream of CIFS reads from the RPi to the NAS, with only a 60K buffer, but this seems to be fine over the 'Ethernet over Mains' connection.
So the 'take away' from this is, if you have to use 'Mains Plugs' because you are unable to have a hardwired Ethernet connection between NAS, UPnP Server and Network Player, make it between the UPnP Server and the NAS, and not the Network Player and the UPnP Server.

Network Player <---Hardwired Ethernet---> Asset UPnP on RPi <--Ethernet over Mains--> NAS over
Network Player <--Ethernet over Mains---> Asset UPnP on RPi <--Hardwired Ethernet---> NAS

Hi Simon, I've been away for a few weeks, great to see you got this sorted, nice work!

Update 10th January

- Removed support for serving resized album art images on ARM machines
- Scanning no longer recurses into hidden folders (dot-prefixed, .folder).
- Greatly reduced CPU & RAM usage when refreshing large librarires
- Faster response to user requested library refresh
- Removed unnecessary full library rescan in certain configuration change scenarios.
- Improved internet radio compatibility.
- Improved application stability.

Installed last evening without issue. All seems to be functioning fine and stable.
The periodic rescan is using a lot less CPU & much quicker with my library of 17,504 tracks. What's cool, is that this doesn't cause the disks in ReadyNAS Duo NAS to spin up once 'Sleeping'. It is just using Cache? If so, pretty cool.
Thanks,

Re: Asset UPnP for Raspberry pi

The OS on the NAS could cache the file tree if it has not changed yes.

So how large is the file tree going likely to be? My ReadyNAS Duo has 1GB of RAM. Next NAS, a ReadyNAS Ultra 2+ has 2GB - will I be able to keep the file tree in the NAS cache?

Pretty damn cool.

Re: Asset UPnP for Raspberry pi

Updated the 10th February build here.. all went well.. database didn't need rebuilding. Rescan of CIFS mounted NAS is noticeably quicker. Still sounds great on my Naim equipment.

Re: Asset UPnP for Raspberry pi

I have just tried this binary on a BeagleBone Black running Debian. It runs quite well and the Beagle is faster than the Pi which should help with transcoding.

Is it possible to register this version? If so how?

I'm also interested if the codecs used for transcoding could be compiled to take advantage of the hardware acceleration (NEON etc.) on the Beagle?

Re: Asset UPnP for Raspberry pi

It is not currently possible to register.

No hardware acceleration is possible.

It is not currently possible to register.

Thanks for the reply. Does this mean the internet radio features will be disabled after 30 days?

Updated to this Beta release without issue, functioning fine and stable.
Are you nearing full release?

Thanks,

Re: Asset UPnP for Raspberry pi

Hi,
I have just got an album of DSD128 (.dsf) 1 bit/5.64 MHz tracks - normally with SACDs I get them as ISOs rather the individual .dsf or dff files and use foobar2000 to read the ISO and extract the tracks as FLAC files.
Can Asset on RPi serve these after transcoding them to WAV?
Also does the DSD plugin for dBPoweramp support DSD128? At present it does not convert them to a playable FLAC files.

Thanks,
Simon.

Re: Asset UPnP for Raspberry pi

128 is not supported by our codecs currently.
