   THEOplayer

Events

• Media Object Request (content) - Fired after the player has requested an object related to video playback. This object may be a manifest, audio/ video segment or subtitle file. The player will fire this event after the full roundtrip of request and response has completed.

Fluxdata

• Stall Duration - Content - The cumulative amount of time elapsed where the user's playback of Content has been interrupted by an unexpected video stall due to buffer depletion.

metadata

• Buffer Length (CMCD) - The buffer length associated with the media object being requested.
• Buffer Starvation (CMCD) - Key is included without a value if the buffer was starved at some point between the prior request and this object request, resulting in the player being in a rebuffering state and the video or audio playback being stalled. This key MUST NOT be sent if the buffer was not starved since the prior request. If the object type ‘ot’ key is sent along with this key, then the ‘bs’ key refers to the buffer associated with the particular object type. If no object type is communicated, then the buffer state applies to the current session.
• Content ID (CMCD) - A unique string identifying the current content.
• Deadline (CMCD) - Deadline from the request time until the first sample of this Segment/Object needs to be available in order to not create a buffer underrun or any other playback problems.
• Encoded Bitrate (CMCD) - The encoded bitrate of the audio or video object being requested. This may not be known precisely by the player; however, it MAY be estimated based upon playlist/manifest declarations. If the playlist declares both peak and average bitrate values, the peak value should be transmitted.
• Measured throughput (CMCD) - The throughput between client and server, as measured by the client and MUST be rounded to the nearest 100 kbps. This value, however derived, SHOULD be the value that the client is using to make its next Adaptive Bitrate switching decision. If the client is connected to multiple servers concurrently, it must take care to report only the throughput measured against the receiving server. If the client has multiple concurrent connections to the server, then the intent is that this value communicates the aggregate throughput the client sees across all those connections.
• Object Type (CMCD) - The media type of the current object being requested: m = text file, such as a manifest or playlist a = audio only v = video only av = muxed audio and video i = init segment c = caption or subtitle tt = ISOBMFF timed text track k = cryptographic key, license or certificate. o = other If the object type being requested is unknown, then this key MUST NOT be used.
• Playback Rate (CMCD) - 1 if real-time, 2 if double speed, 0 if not playing. SHOULD only be sent if not equal to 1.
• Request ID (CMCD) - A unique identifier that is established to track an individual media object request made from the client to a CDN.
• Requested Maximum Throughput (CMCD) - The requested maximum throughput that the client considers sufficient for delivery of the asset. Values MUST be rounded to the nearest 100kbps. For example, a client would indicate that the current segment, encoded at 2Mbps, is to be delivered at no more than 10Mbps, by using rtp=10000. Note: This can benefit clients by preventing buffer saturation through over-delivery and can also deliver a community benefit through fair-share delivery. The concept is that each client receives the throughput necessary for great performance, but no more. The CDN may not support the rtp feature.
• Session ID (CMCD) - A GUID identifying the current playback session. A playback session typically ties together segments belonging to a single media asset. Maximum length is 64 characters. It is RECOMMENDED to conform to the UUID specification [7].
• Startup (CMCD) - Key is included without a value if the object is needed urgently due to startup, seeking or recovery after a buffer-empty event. The media SHOULD not be rendering when this request is made. This key MUST not be sent if it is FALSE.
• Stream Type (CMCD) - Describes if the content being streamed is Live or On Demand.
• Streaming Format (CMCD) - The streaming format that defines the current request. d = MPEG DASH h = HTTP Live Streaming (HLS) s = Smooth Streaming o = other If the streaming format being requested is unknown, then this key MUST NOT be used.
• Top Bitrate (CMCD) - The highest bitrate rendition in the manifest or playlist that the client is allowed to play, given current codec, licensing and sizing constraints.
• Version (CMCD) - The version of the CMCD specification used for interpreting the defined key names and values.
