Hello @Mehdi_Mastouri, we only offer this through direct integration through Streaming Cloud right now and it requires special account permissions.
First, request access to the live video broadcasting feature on LinkedIn. See Applying for Live Video Broadcasting to request approval. LinkedIn Live is only available to a limited group of members and organizations.
Once you are approved to use LinkedIn Live, email cloud-preview@wowza.com to request access to the Wowza Streaming Cloud private preview for LinkedIn Live stream targets. Participation is by invitation only and is subject to the terms of the Wowza Preview End User License Agreement.
