Question: What information is included in the `CodecInfo` metric for video media in the Default Reporting Format for Transparent end-to-end Packet-switched Streaming Service (PSS)?
Option 1: Audio codec type and sample rate
Option 2: Video codec type, profile, level, and image size used during the measurement period
Option 3: Only the video codec type, as represented in an SDP offer
Option 4: Timed text media encoding and maximum allowed image size from SDP negotiation
Explanation: For video media, the `CodecInfo` metric includes detailed information to accurately describe the video settings used during the measurement period. This encompasses not just the type of video codec (e.g., H.264) but also the specific profile and level (which dictate capabilities and compatibility) and the actual image size utilized.
