Universal Media Server | Forum

Hi
I have a problem with clients erroring on directories with large number of files. It seems dependent on renderer, but not sure how to deal with it

ROKU box seems to work OK
Android - two clients with differing level of problem
slick UPNP - works with list with 768 files, but fails with more
Nova Video Player - fails with a lower number (around 300)

Both of these use the android renderer

Any ideas appreciated

You have to give more information of the nature of the "problem". There are two possible causes for issues with large folders that I can think of:

1) Timeout. UMS must "build" the complete "document" that is sent in response to a browse request before it responds, the UPnP protocol doesn't allow this to happen progressively, so for folders with a large number of media files this can take a substantial amount of time. Renderers have a timeout value, which the UPnP spec dictates that it should be around 30 seconds, but in my experience it's usually shorter. If the renderer decides that it has waited long enough while UMS is still building the "document", the renderer will probably serve you some kind of error or just "jump back" to where you were. If this is the case, trying to enter the folder again after giving it some time could work, as UMS will reuse some of the work it did from the last attempt making the second go a bit faster.

2) Renderer limit for the maximum number of media resources. There's not supposed to be any such limit according to the spec as far as I know, but many implementations have limitations in reality. There is a setting in UMS's renderer configuration that can make it make "fake folders" if the number of resources exceeds a certain threshold, but I'm not sure how well it works.

Some more information about what constitutes the "problem" might shed some light as to what the situation is.
