Hey! Seems like your implementation should work as expected:

- **API supports sending share frames (I420):** The Linux interface exposes `sendShareFrame(...)` which accepts l420 data ([docs](https://arc.net/l/quote/komzlxnv))

- **External-share workflow makes sense:** _`setExternalShareSource(…)`_ [starts sharing external source](https://marketplacefront.zoom.us/sdk/meeting/linux/class_i_zoom_s_d_k_share_source_helper.html#aa8dff888ac6ad368390aaf30de5b8d3d) and _`onStartSend(IZoomSDKShareSender`_`)` [callback for share source can start send raw data](https://marketplacefront.zoom.us/sdk/meeting/linux/class_i_zoom_s_d_k_share_source.html#a445914f2a8f48f7e480bd23e83fb7d7e). You can find the interface [here](https://marketplacefront.zoom.us/sdk/meeting/linux/rawdata __share__ source __helper__ interface_8h_source.html)

- **Your sequence is valid (set external source → `onStartSend` → `sendShareFrame`):** The same header defines `onStartSend(...)` and `sendShareFrame(...)`, establishing the order you’re using and you’re receiving success response codes

Given that you’re not receiving the video stream in the meeting even after following their docs, there’s a few things for you to check:

- Confirm sharing is allowed in the meeting (policy/state): `IMeetingShareController` exposes `CanStartShare(...)` and `IsDesktopSharingEnabled()` ([class reference](https://marketplacefront.zoom.us/sdk/meeting/linux/class_i_meeting_share_controller.html))

- Try an adjacent SDK versions (to rule out potential regressions)

Alternatively, you could use a third party service like [Recall.ai](https://www.recall.ai/?utm_source=dev_forum&utm_medium=forum_answer) which allows you to stream content into a Zoom meeting with a single api call
