Audio playback tuning in iOS Safari
If one video stream is playing and then another video stream is publishing on the same page (videochat case for example) in iOS Safari, the sound level may change for stream played. This can be escaped by the following ways:
1. Query media devices access on session creation before playing a stream
| Code Block | ||||
|---|---|---|---|---|
| ||||
Flashphoner.createSession({urlServer: url}).on(SESSION_STATUS.ESTABLISHED, function (session) {
...
if (Browser.isSafariWebRTC() && Browser.isiOS() && Flashphoner.getMediaProviders()[0] === "WebRTC") {
Flashphoner.playFirstVideo(localVideo, true, PRELOADER_URL).then(function () {
Flashphoner.getMediaAccess(null, localVideo).then(function (disp) {
});
});
}
...
}); |
2. 1-1,5 seconds after PLAYING stream status receiving, mute and unmute video and/or sound
| Code Block | ||||
|---|---|---|---|---|
| ||||
session.createStream({
name: streamName,
display: remoteVideo
}).on(STREAM_STATUS.PENDING, function (stream) {
...
}).on(STREAM_STATUS.PLAYING, function (stream) {
setStatus("#playStatus", stream.status());
onPlaying(stream);
if (Browser.isSafariWebRTC() && Browser.isiOS() && Flashphoner.getMediaProviders()[0] === "WebRTC") {
setTimeout(function () {
muteVideo();
unmuteVideo();
}, 1500);
}
...
}).play(); |
