A videoconference may be initiated between a plurality of endpoints. At least one of the endpoints may be coupled to a recording server, which may be configured to record the videoconference. A configuration may be selected (e.g., automatically or manually) for performing the recording. The endpoint (e.g., acting as an MCU) may transmit information to endpoints and may transmit recording information to the recording server. The recording information may be different from the videoconference information. For example, it may be in a 'streaming friendly' format, at a different bit rate, encoded differently, have different inputs, etc. The manner in which the videoconference is stored and/or recorded may be based on the selected configuration. Clients may be configured to receive and display the videoconference from the recording server and may be configured to change the provided layout to different layouts, e.g., based on user input.

DMA transfer of audio and video data. The audio and video data may be received over a serial bus. A DMA engine may provide audio and video data packets to data storage logic based on the audio and video data. The DMA engine may provide each of the audio data packets with a first, same destination address of a first memory and may provide each of the video data packets with a second, same destination address of the first memory. The data storage logic may maintain first and second pointers that indicate a next current memory location for audio data in a first buffer and video data in a second buffer in the first memory, respectively. The data storage logic may receive and store the audio and video data packets at respective locations in the first and second buffers based on current values of the first and second pointers.

Supporting a plurality of videoconferencing streams in a videoconference. The method may include receiving the plurality of videoconferencing streams and may include decoding a first videoconferencing stream of the plurality of videoconferencing streams. The method may also include selecting, for decoding, a second videoconferencing stream of the plurality of videoconferencing streams. The second videoconferencing stream may not be the first videoconferencing stream. The method may further include decoding, in response to said selecting, the second videoconferencing stream of the plurality of videoconferencing streams.
