I am using 2 MC library servers (v21.0.50) (MC-1, MC-2) in a LAN on a MacMini (MC-1) and MCBookPro (MC-2) (with different access keys). The files of a master library 'ML' of MC-1 are stored on a NAS (TimeCapsule) in the LAN. MC-2 uses this library as a client (in sync mode). Everything works perfect with this installation.
The problem starts, if I use the MCWS on MC-2 to execute a '/MCWS/v1/File/GetFile?File=key&Conversion=4'-request in a Safari-Browser-page on MC-2 to fill the src-attribute of an HTML5 audio element. The file downloads and (if clicked) plays in the browser (on the default audio device), but shortly after the file is fully downloaded its deleted on the NAS (TimeCapsule). On MC-1 (in the corresponding zone display) the filename vanishes and is replaced by 'GetFile -Cache MP3 high (number).mp3'. The display is not updated on MC-2. Clicking (in MC-1) on a track (where the file is deleted) shows the error message 'Tagging Error', Media Center encountered errors while tagging or moving files....'.
Here is the 'squeezed down to the error' HTML-page which causes this deleting of files

I do not know, if this is an MC-error or my error using 'File/GetFile' in wrong way. Any hints would be very valuable.

I believe it is because you are using the Conversion flag. That creates transient files for streaming, which are automatically removed after use. It is the converted file MC is creating that is being deleted, right?
-
no, unfortunateley not. It is the original .flac-file which is deleted. The converted file will also be deleted as soon as the play in the web finishes.
-
Woah! That's not good.
I'll need to test it to see what might be going on. One thing, why do you have a token value hardcoded? Was that just to simplify your code for demonstration purposes?
-
yes, just to make it as compact as possible. I am working on a web remote for JRiver collecting all available information of web services (rovi,wikidata,wikpedia,musicbrainz and so on) for classical music metadata of the music file which is just playing in Playing Now of a selected zone and for this reason I have also included a web player similiar to Gizmo or JRemote in my project. All works fine, but I do have this problem for the zone "this device". The code snipet is just the error which causes the problem.
-
I'm trying to reproduce this, but I must be missing a step because it works fine.
I enter this URL:
http://localhost:52199/MCWS/v1/File/GetFile?File=931&FileType=Key
That downloads the file with the web browser. Then I switch back to Media Center and play it no problem (so it hasn't been deleted).
Is it only if you specify conversion or something?
Well I tried to specify a conversion and that also worked fine.
Thanks.

Thanks Matt for checking. Perhaps I was not precise enough. My point is not downloading files using MCWS 'File/GetFile'-requests. This works fine without any problem as long as I address this request to the library server to which this library is local. My problem arises when I address this request to the library server MC-2 which uses the library of another MC library server (MC-1) as a client. Then on MC-1 the files were deleted.
But I can solve my problem by just adressing the request allways to a library server which 'owns' the library respec. where the library is local and not making things more complex than neccessary.
Thanks again.
-
I connected to a library server and pulled the file (with and without conversion) and the library server didn't erase the file either.
-
Ok, thanks for testing again. Then let me try to test a little be more and come back when I think I can isolate it to a better reproducible test case.

I think the OP is describing this setup:
Server MC with media connected via NAS.
Client MC, connected to Server in "sync mode".
MCWS, run on Client with get file command *and* conversion mode specified.
I think I got that right. A very specific and somewhat unusual setup.

I think it can make sense in a developer enviroment: 1 'production' machine, 1 'developer' machine, both with its own MCWS & web server, both accessing the same physical files on a NAS with the option for the developer installation to test (as a client) with the 'production' library.
