Android WebRTC - getStats() не предоставляет достаточно информации
Я пытаюсь получить всю информацию, связанную со средними потоками, чтобы получить качество звонка. Метод Peerconnection.getStats() устарел, но предоставляет всю информацию в соответствии с моим требованием, такую как "bytesReceived", "packetLost", "packetReceived","googCodecName" и "googJitterBufferMs".
peerConnection.getStats(reports -> {
for (StatsReport report : reports) {
Log.d(TAG, "Stats: " + report.toString());
}
}, null);
Response:
{

bytesReceived: 951618

[

Теперь я не могу использовать этот метод как устаревший. Когда я пытаюсь использовать новый метод getStats (), он не предоставляет всей такой информации, а также ответ очень неорганизован.
peerConnection.getStats(new RTCStatsCollectorCallback() {
@Override
public void onStatsDelivered(RTCStatsReport rtcStatsReport) {
Log.d(TAG, "RTCStatsReport: "+rtcStatsReport.getStatsMap().toString());
}
});

Я запускаю метод getStats () через каждую секунду, и каждый раз он дает мне ответ с различными данными. Этот ответ не документирован нигде в документах WebRTC.
Как я могу получить "bytesReceived", "packagesLost", "packetReceived","googCodecName" и "googJitterBufferMs" с помощью нового метода getStats ().

Вы можете найти их в своей статистике?
Я называю это так:
peerConnection.getStats(new RTCStatsCollectorCallback() {
@Override
public void onStatsDelivered(RTCStatsReport rtcStatsReport) {
longInfo("RTC Stats: \n" + rtcStatsReport.toString());
}
});
Изменить: поскольку отчет статистики такой длинный, вам нужно будет создать такой метод longInfo, чтобы увидеть все. Это должно решить вашу проблему.
public void longInfo(String str) {
if (str.length() > 4000) {
Log.i(TAG, str.substring(0, 4000));
longInfo(str.substring(4000));
} else
Log.i(TAG, str);
}
