(registered by RFC7741) Type name: video Subtype name: VP8 Required parameters: None. Optional parameters: These parameters are used to signal the capabilities of a receiver implementation. If the implementation is willing to receive media, both parameters MUST be provided. These parameters MUST NOT be used for any other purpose. max-fr: The value of max-fr is an integer indicating the maximum frame rate in units of frames per second that the decoder is capable of decoding. max-fs: The value of max-fs is an integer indicating the maximum frame size in units of macroblocks that the decoder is capable of decoding. The decoder is capable of decoding this frame size as long as the width and height of the frame in macroblocks are less than int(sqrt(max-fs * 8)). For instance, a max-fs of 1200 (capable of supporting 640x480 resolution) will support widths and heights up to 1552 pixels (97 macroblocks). Encoding considerations: This media type is framed in RTP and contains binary data; see Section 4.8 of [RFC6838]. Security considerations: See Section 7 of RFC7741. Interoperability considerations: None. Published specification: VP8 bitstream format [RFC6386] and [RFC7741]. Applications that use this media type: For example: Video over IP, video conferencing. Fragment identifier considerations: N/A. Additional information: None. Person & email address to contact for further information: Patrik Westin, patrik.westin&gmail.com Intended usage: COMMON Restrictions on usage: This media type depends on RTP framing, and hence is only defined for transfer via RTP [RFC3550].
