Hi @Venkat_Koushik, on the Linux Meeting SDK you can only grab individual participant video streams - there’s no built-in gallery view, so you’ll need to composite those streams yourself.
For screen share, the SDK flow you described is correct. You start with setExternalShareSource(...), wait for the onStartSend(...) callback, then push frames with sendShareFrame(...). That sequence is the intended workflow, and you can see my other detailed answer here.
Live transcription isn’t available on the Linux SDK - there’s no caption controller today. The workaround is to capture the raw PCM audio and run it through your own STT service.
For syncing events like speaker changes, Zoom provides a timeline file in cloud recordings, which you can fetch through the Recording API.
Alternatively, you can use a third party service like Recall.ai which makes this easy with one api call.
