Quality of service (QoS) offers a detailed view into how the video engine is performing. TVSDK provides detailed statistics about playback, buffering, and devices.
TVSDK also provides information about the following downloaded resources:
Tracking information for files
You can read quality of service (QoS) information about downloaded resources, such as fragments and tracks, from the
onLoadInfo callback event listener.
Register the event listener, which TVSDK calls every time a fragment has downloaded.
Read the data of interest from the
LoadInfo parameter that is passed to the callback.
The duration of the download in milliseconds.
TVSDK does not differentiate between the time it took the client to connect to the server and the time it took to download the full fragment. For example, if a 10 MB segment takes 8 seconds to download, TVSDK provides that information, but does not tell you that it took 4 seconds until the first byte and another 4 seconds to download the entire fragment.
