|
|
* Watch both: a sustained mute for >windowMs = the publisher is
|
|
* (probably) gone and we remove the tile. If 'unmute' fires within
|
|
* the window — transient network blip, NACK retransmission gap, brief
|
|
* CPU pressure on publisher, mobile network handoff, OR (for screen
|
|
* shares) a long stretch of static content where the encoder simply
|
|
* isn't producing RTP — we cancel the removal.
|
|
*
|
|
* Window depends on the kind of content (caller passes via windowMs):
|
|
* - 60s for cameras: face/motion content keeps RTP flowing most of
|
|
* the time, but Firefox Android + cellular handoffs can stall a
|
|
* decoded video element on jittery paths well past 15s without
|
|
* the publisher being gone. 60s is comfortably above the typical
|
|
* NACK + transport-cc recovery window; matches Pion's ICE
|
|
* failure timeout, so if the path is genuinely broken the SFU
|
|
* fires renegotiation + 'ended' before this anyway.
|
|
* - 120s for screen / gameshare: STATIC content (still desktop, a
|
|
* paused video, a code editor with no caret motion) doesn't push
|
|
* new RTP for long stretches. The encoder genuinely stops emitting
|
|
* packets; 120s lets a static screen survive comfortably.
|
|
*
|
|
* Genuine unshares always resolve through the 'ended' path (within a
|
|
* frame of the SFU's removePubFromSub), so these windows only matter
|
|
* for slow-failure scenarios (PC dies silently, SSE renegotiation
|
|
* dropped, etc.).
|
|
*
|
|
* Window history:
|
|
* - 3s (all kinds): killed live tiles on any transient mute.
|
|
* - 15s (all kinds): cameras ok on desktop, static screens vanished.
|
|
* - 15s camera / 120s screen+game: cameras OK on desktop, phone on
|
|
* cellular still occasionally reaped live faces during jitter.
|
|
* - 60s camera / 120s screen+game (current). */
