WalkthroughA shell script automates SFU proto generation from the GetStream protocol repository. The signaling system gains a metrics-reporting RPC. Participant pinning state now uses SessionId types instead of raw strings. Event models are extended with pinned participant flags, and RTP-related protobuf messages are introduced for metrics collection. Changes

Inline comments:
In `@generate-sfu.sh`:
- Around line 23-35: The git clone invocation always passes --branch
"$REFERENCE_VALUE", which breaks when REFERENCE_TYPE="commit" because commit
SHAs are not branch names; change the logic so clone does not include --branch
for commit mode (e.g., branch/tag: use --branch "$REFERENCE_VALUE", commit:
clone without --branch or clone with --no-checkout and then fetch/checkout the
SHA). Update the script around the git clone and the REFERENCE_TYPE conditional
to handle REFERENCE_TYPE ("branch", "tag", "commit") separately so that when
REFERENCE_TYPE is "commit" the clone succeeds and the subsequent git fetch/git
checkout of REFERENCE_VALUE (the SHA) in the commit branch-handling block (the
lines referencing REFERENCE_TYPE, REFERENCE_VALUE and the git fetch/checkout
commands) is reached and used.
In
`@stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/CallState.kt`:
- Around line 1107-1112: Replace the leftover debug call using
android.util.Log.d("Noob", ...) with the module's logger: use the existing
logger instance (logger) to emit the same message at an appropriate level (e.g.,
logger.d or logger.v) and include the _serverPins.value.map { it.key
}.joinToString(",") payload; guard the log emission behind
StreamVideoImpl.developmentMode (or existing development-mode check) to respect
verbosity rules and avoid hardcoded tags.
- Around line 1268-1281: The debug Log.d call in updateServerSidePins (the one
using hardcoded "Noob" tag and printing
pins/internalParticipantsText/pinnedInCall) must be removed or replaced with the
module logger and guarded by StreamVideoImpl.developmentMode; locate the Log.d
invocation inside updateServerSidePins and either delete it or change it to use
the existing logger (e.g., logger.debug/trace) and wrap the log emit with a
developmentMode check so production builds don't leak verbose debug output.
- Around line 1505-1507: The code creates an unused local variable
participantNames via participants.joinToString in CallState.kt; remove the dead
assignment (the participantNames declaration) from the enclosing function or
block (or, if intended for logging, replace the unused variable with a direct
log/usage) so there is no unused local variable left; ensure no other logic
depends on participantNames before deleting.
In
`@stream-video-android-core/src/test/kotlin/io/getstream/video/android/core/CallStateTest.kt`:
- Around line 131-137: The test constructs a PinUpdate with arguments reversed
relative to the implementation: when map key "1" is the sessionId, the PinUpdate
must be created as PinUpdate(userId, sessionId) to match CallState.pin()
behavior; update the call to call.state.pins.updateLocalPins(...) so the map
entry uses PinUpdate("userId", "1") (wrapped in PinUpdateAtTime) instead of
PinUpdate("1", "userId") so keys and PinUpdate fields align with the
PinUpdateAtTime/PinUpdate usage.

Goal
Solves the gap where:
pinned participant leaves
joins again with another session
existing participants have obsolete pins information, and render the user unpinned
ParticipantJoinedSFU event now will carryis_pinnedproperty so you can use it for updating the client-side state correctlyImplementation
