IWMPNetwork::get_lostPackets method (wmp.h)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The get_lostPackets method retrieves the number of packets lost.

[out] long *plLostPackets

Remarks
This method retrieves streaming media packets only, and will equal zero when using the HTTP protocol, which is lossless.
Packets may be lost for a number of reasons, such as the type and quality of the network connection.
Each time playback is stopped and restarted, the value retrieved from this method is reset to zero. The value is not reset if playback is paused. This method retrieves valid information only during run time when the URL for playback is set by using the IWMPCore::put_URL method.
