Bandwith detection for preloading

[AdrianaBaron]

I dont know if this question applies here but I'll give it a try... I would like to know if with this tool is there anyway to detect the bandwith of the end user as I would like to preload more when the connection is slow and preload less when its fast... Does anyone knows how to do this and point me into an example? I would greatly appreciate it!!

Sure, you could use the "loadTime" property along with the bytesLoaded to figure it out.

 

queue.bytesLoaded / queue.loadTime;

 

Of course you'd want to wait for it to run for at least several seconds before you poll the number so that it's got some data to work with.

Please forgive my ignorance but which units will this return... I couldnt find on the docummentation what does the LoadTime return... sorry I mean I dont know how to interpret this information

[GreenSock]

No problem - it's in the ASDocs (inherited by all loaders from LoaderCore).

 

loadTime : Number - The number of seconds that elapsed between when the loader began and when it either completed, failed, or was canceled.

 

Therefore, this would give you the bytes per second:

queue.bytesLoaded / queue.loadTime;

Sure thanks now I did a trace on my progress of those values but look at this:

Why is the load time always 0? when it has passed some time? but as soon as the buffer is full then it starts changing this value? One thing I noticed is that the status is 0 which means that the LoaderStatus.READY therefore thats why it returns a 0... but why is it ready if its loading something? i dont understand sorry...

 

Also Im prioritizing this loader with prioritize(true);

Could you post (or send me) your code? It looks like you might be checking the bytesLoaded on the entire queue but the loadTime of a particular child loader that hasn't started loading yet. The loadTime will start when the loader starts loading (of course), so if the queue hasn't reached it yet, it will be zero until it does. But again, it's very difficult to troubleshoot without seeing your code and being able to test publish an FLA or something to which I can add trace() statements myself. Could you send an example? It doesn't need to be your production files. I just tested loadTime on a LoaderMax queue and it seemed to work perfectly. Oh, and make sure you're using the latest version of course. http://www.LoaderMax.com

Yeah you were right I was checking against a subloader... sorry

 

By the way if I do this

 

1. LoaderMaxA.load()

2. LoaderMaxB.append(LoaderMaxA)

3. LoaderMaxB.load()

 

if the LoaderMaxA hasnt finished loading but I append it to the LoaderMaxB and then say to it to load, will that open new threads or something that will actually load LoaderMaxA as well? I mean at the same time 2 loaders will be loading LoaderMaxA?

 

Thanks

 

 

Sorry and one more question: is it possible to set the buffer of a VideoLoader after It has been set on the vars properties? like I dont use the vars class cos i dont know how to I place the vars when I create the VideoLoader object...

...if I do this

 

1. LoaderMaxA.load()

2. LoaderMaxB.append(LoaderMaxA)

3. LoaderMaxB.load()

No, don't worry - LoaderMax will intelligently handle that situation. If LoaderMaxA is in the process of loading LoaderMaxB will notice that and let it do its thing. It doesn't force new threads to open or anything like that.

 

is it possible to set the buffer of a VideoLoader after It has been set on the vars properties? like I dont use the vars class cos i dont know how to I place the vars when I create the VideoLoader object...

 

Do you want to set the bufferTime of the NetStream or the bufferMode of the VideoLoader? If you want to set the bufferTime of the NetStream, you'd do myVideoLoader.netStream.bufferTime = myValue. But keep in mind that the NetStream gets recreated whenever the VideoLoader is canceled or unloaded so I'd still recommend setting bufferTime in the loader's vars object too. myVideoLoader.vars.bufferTime = myValue. If you want to set the bufferMode, you'd do myVideoLoader.bufferMode = true;
