Indeed. It's not a full solution as it doesn't support multiple streams, audio or other encoding types. But if you want to get the audio then you need to add the decoding case (parse is the nomenclature used here) for the audio packets in the read payload case structure.

Just an FYI...I found this software very helpful in playing ,setting and testing IP cameras.

If you look at the actual array sizes, things will make a lot more sense. 1. The Build Array will add the number of expanded elements to the first dimension. The array size after the first Build Array is (2,0), which is still an empty array. 2. The Transpose Array will swap the array sizes. The array size after the Transpose Array is (0,2), which is still an empty array. 3. Again, the Build Array will add the number of expanded elements to the first dimension. In this case, it will add 1 to the first dimension, resulting in the array size being (1,2), which is no longer an empty array.

IIRC there are a couple of RTSP libs for around (a while ago now). Some are based on using the VLC DLL's and I even saw one that was pure LabVIEW. Might be worth having a look at them for "inspiration".

What doesn't work with the function: AJ_NETSDK_IPC_PTZControl() on page 21/22? Or are you not using the SDK functions to retrieve the RTSP stream but some other ready made interface for LabVIEW? Meaning you have no idea how to interface to a DLL? A few points to consider: 1) The camera may not like a secondary connection, either through the SDK or through generic TCP/IP while it is busy streaming image data to the VLC or whatever interface. 2) Trying to reverse engineer the TCP/IP binary stream protocol is likely going to be cumbersome and difficult to realize as it is usually proprietary. The SDK interface is simple enough to use, except if you lack any and all understanding about C programming. It's not a CIN node either that you will need to configure but a CLN (Call Library Node). CINs are not only legacy technology but on most modern LabVIEW versions simply not supported anymore. An interesting problem, but none I can help you as I do not have that hardware, and I would expect it to be a bit cumbersome considering above 2 points.

Started playing with XNodes a bit and noticed the same behaviour as well. Really upsetting. But there is the solution. Just send FailTransaction reply in a Cancel case in the OnDoubleClick ability of your XNode and that 'dirty dot' never appears! That's exactly what the Timed Loop XNode does internally. Looking at this description I get the impression that this reply was invented precisely to overcome that bug (was even given its own CAR #571353). Similar thread for cross-reference: LabVIEW Bug Report: Error Ring Edit + Cancel modifies the owning VI

I can confirm that LabVIEW 2018 SP1 f4 (32-bit) automatically selects LabVIEW Runtime 2018 SP1 f5 when "automatically select recommended installers" is checked and LabVIEW Runtime 2018 SP1 f5 is installed. Though, it does not ask for the installer source. There used to be SFX installers that were extracted to "C:\National Instruments Downloads". When such an installer was used, the destination folder must not be deleted as it is used as a source location when creating installers in LabVIEW. Perhaps you installed the runtime engine through an old SFX installer and deleted those files at some point?
