![]() For wrapper data sources forwarding to other data sources, addTransferListener needs to register the TransferListener on the inner data source.The constructor of BaseDataSource takes a boolean indicating whether the source loads data over network. For data sources directly accessing the underlying resource, it is advisable to use BaseDataSource as a super-class which automatically handles listener registration.There are two types of data sources: Those which directly load data from the underlying resource and those which are just a wrapper and forward loading to another data source. The actual implementation depends on the type of data source used. DataSource implementations need to support adding a new transfer listener with addTransferListener.Note that this will most likely mean that you need to forward the transfer listener to all created media periods as this is where data sources will eventually be created. It displays real-time graphical details about your network. For each of these media data sources, call dataSource.addTransferListener(transferListener). The Bandwidth Meter application will monitor all your internet, LAN, WAN or WiFi network traffic. Do not forward it to data sources loading other data like manifests. Other ISPs call it similar things, generally involving the word Usage. ![]() It is not intended to represent actual speeds to the. This transfer listener needs to be forwarded to all DataSource objects used to load media data. Cox calls this a Data Usage Meter, while AT&T calls it myAT&T Usage. This bandwidth test is intended for personal backup for home users and is for informational purposes.MediaSource implementations will get a TransferListener in calls to prepareSourceInternal (assuming you are using BaseMediaSource).They also need to support adding and removing listeners via addEventListener and removeEventListener.In most cases this will just be the BandwidthMeter itself. BandwidthMeter implementations need to return the TransferListener they are using to measure bandwidth in getTransferListener.This bandwidth meter should be used to make all bandwidth related adaptive track selections. Data usage meters or network bandwidth monitors are valuable tools for making sure that you stay within your plan’s restrictions so that your connection speeds aren’t throttled by your ISP. TrackSelection.Factory implementations will get a BandwidthMeter in their createTrackSelection method. Internet service providers (ISPs) commonly use data usage caps to limit the amount of bandwidth that enterprises can use.TrackSelector implementations need to accept the BandwidthMeter passed to TrackSelector.init(.) and forward it to all adaptive track selection factories in the respective Factory.createTrackSelection calls.To adapt your code to this new structure, the following changes to custom components need to be made: TrackSelector A bandwidth-meter service simply measures, at regular intervals, the bandwidth usage of one or more network links, making measurement traces available as.
