50 Objects only in network folder shown up

[SBA]

Hi There,
First a big ‘Thank You’ to all the contributors of VLC.
Actually I have an issue with the current iOS version of VLC Version: 3.1.7 (322) on two different iPhones in combination with NAS functions of the at least in Germany very popular AVM Fritzboxes 7490 and 7590.
I have more than 50 objects in a directory on the NAS drive formatted in NTFS attached to either of these two routers with NAS functions. But the VLC Player for iOS does not show up more than 50 objects (files and directory names) in the according network directory.
Using an Amazon FireTV stick (connected by upnp) full access(es) to all more than 50 objects in the same directories is (are) possible.
So I can limit the issue most certainly to the iOS-version of VLC.
Using a plain browser for the Fritzboxes GUI, also all files show up.
Anyone with an idea?
Thanks!

Are those UPnP folders?

[SBA]

I’d guess they are UPnP, since I am not an expert. The Fritzbox with the NAS drive is set to run as Media Server, stating that the playing device must support Standard UPnP. And when I use VLC (connecting with UPnP) on the FireTV stick, I have full access to all approx 200 files and directories in the directory instead of the alphabetical ordered first 50 ones while using VLC on the iPhone.

OK. Will try to improve/fix

[SBA]

That would be great. Thanks a lot.

Saw todays’ VLC for iOS update but it seems as if this bug did not get fixed?
Changelog isn‘t telling too much.

I referred to AVM’s support team (manufacturer of the FritzBoxes). After several days of analysis in second and third level they replied that the error is located in the client. The Fritzboxes always deliver 50 items per request to prevent overloads in networks or clients. They declare this method as a usual way. The error must be in the client not requesting a further 50 items. They told me to look into the clients setting (how much I love such advices as a user) and adjust accordingly. Since I don’t know of any ways to change such a setting by myself I hope that this helps the VLC team to find a way to fix this. At least this message might help you in finding the bug.
Thanks a lot and best regards.

I can confirm the issue when using the VLC mobile client on iPad and iPhone with current iOS. In the VLC mobile app only the first 50 subfolders are displayed from a mediaserver running on a AVM FRITZ!Box 7590 or 7490. Surprisingly, the desktop version of the VLC player installed on a current macOS Mojave shows all available subfolders of the mediaserver. Additionally, on a FRITZ!Phone connected to the FRITZ!Box all subfolders are displayed and music titles can be selected and played.
Using the VLC app on an Apple TV I am facing the same probleme as described: Only the first 50 subfolders are displayed.

Thanks for taking the time to discuss this issue with AVM. In fact, this is limited to the specific UPnP stack used by VLC on iOS and tvOS and is only an issue with their devices. Coaccidentally, I discovered one of those devices at one of my friend's places and will try to fix it as time allows.

@Felix: If this is a bug in VLC for iOS, I wonder if this appears in connection with other manufacturers of UPnP-/NAS Servers, aside from AVM Fritzboxes.

In the meantime I face problems with accessing the same libraries with VLC on the FireTV-Stick. I wonder if this is related or not - then I‘d open another topic in the fireOS-/Android section for VLC. The VLC sums up approx 3000 items on the Fritzbox-NAS, which is correct, but says the directories are empty and does not show up file names. This happens occasionally- the other week it‘s just fine.
That‘s pretty irritating for me as a non-technician.

The iOS/tvOS issue is limited to Fritzbox devices. We never received any complaints about any other devices.

The Android / FireTV port uses a different UPnP library so this is a different problem and should also show on desktop platforms.

It seems as if there were other users affected already more than one year ago. I found this thread https://forum.videolan.org/viewtopic.php?t=144060
which obviously did not ever get any reply.
It would be great to see that fixed soon. I‘d appreciate and suggest a collaboration with the developers of AVM since their products lead the market at least in Germany. That could be of benefit for both - VLC and AVM - since they don‘t have an own working client software anymore for their media servers on Fritzbox.

A collaboration with AVM did not happen in the end, but I found a suitable testing device at a friend's place. The problem is resolved for the forthcoming 3.2.3 update of VLC-iOS.

Thank you very much!
It‘s sad that there wasn‘t anymore support by AVM but some links...

I am running 3.2.6 and still have this issue on iOS when trying to move files from my camera that is acting as server. Only 50 files are shown.
