|
* Instrumented variant of [sustained_real_time_cadence_two_users]
|
||||||
|
* that BYPASSES [com.vitorpamplona.nestsclient.audio.NestMoqLiteBroadcaster]
|
||||||
|
* and calls [com.vitorpamplona.nestsclient.moq.lite.MoqLitePublisherHandle.send]
|
||||||
|
* directly so we can capture per-frame send results.
|
||||||
|
*
|
||||||
|
* Motivation: the production broadcaster wraps every send in
|
||||||
|
* `runCatching { publisher.send(opus); publisher.endGroup() }.onFailure {…}`
|
||||||
|
* and IGNORES the boolean. `send` returns false when
|
||||||
|
* `publisherClosed` or `inboundSubs.isEmpty()`, AND
|
||||||
|
* `runCatching { uni.write(framed) }` swallows write failures while
|
||||||
|
* still returning true. Frame loss is structurally invisible to the
|
||||||
|
* broadcaster.
|
||||||
|
*
|
||||||
|
* This test reproduces the speaker side WITHOUT the broadcaster:
|
||||||
|
* - same auth (OkHttpNestsClient.mintToken)
|
||||||
|
* - same transport (QuicWebTransportFactory)
|
||||||
|
* - same MoqLiteSession.client + session.publish() the
|
||||||
|
* broadcaster uses internally
|
||||||
|
* - records [MoqLitePublisherHandle.send]'s Boolean per frame and
|
||||||
|
* prints it alongside the listener's gap pattern
|
||||||
|
*
|
||||||
|
* Diagnostic table interpretation (sent vs. received per group):
|
||||||
|
* - send=false → speaker dropped the frame at the moq-lite layer
|
||||||
|
* (no inbound subscribers OR publisher closed)
|
||||||
|
* - send=true, received=false → frame was queued by moq-lite, then
|
||||||
|
* lost downstream (uni-stream write swallowed an exception, OR
|
||||||
|
* QUIC flow control / relay dropped the stream)
|
||||||
|
* - send=true, received=true → frame arrived (control)
