Methods, systems, and media for delivering manifestless streaming media content are provided. In some embodiments, the method comprises: receiving, from a user device, a request for a URL corresponding to a format of a live stream that is provided in a plurality of formats, wherein the live stream comprises a plurality of segments for each of the plurality of formats; resolving the request to a specific segment of the live stream based on the URL, wherein the resolving comprises: identifying the format of the live stream associated with the request from the plurality of formats based on the URL; and identifying a segment of the plurality of segments corresponding to the identified format to the user device in a response to the request.

Methods, systems, and media for delivering manifestless streaming media content

A method includes receiving, by a processor, from a first server, a first plurality of frames associated with a media item. Each frame of the first plurality of frames is associated with a respective timestamp of a first plurality of timestamps generated by the first server. A second plurality of frames associated with the media item are received from a second server. The second plurality of frames are each associated with a respective timestamp of a second plurality of timestamps generated by the second server. An offset value between a first timestamp of the first plurality of timestamps and a second timestamp of the second plurality of timestamps is determined. A modified plurality of frames is generated by modifying, based on the offset value, each timestamp of a subset of the second plurality of timestamps. The modified plurality of frames is sent to the client device.

Systems and methods for synchronization of independently encoded media streams

Methods, systems, and media for delivering manifestless streaming media content are provided. In some embodiments, the method comprises: receiving, from a user device, a request for a URL corresponding to a format of a live stream that is provided in a plurality of formats, wherein the live stream comprises a plurality of segments for each of the plurality of formats and wherein each segment of the plurality of segments comprises a respective sequence number; resolving the request to a specific segment of the live stream based on the URL, wherein the resolving comprises: identifying the format of the live stream associated with the request from the plurality of formats based on the URL; identifying a sequence number associated with the request based on the URL; and identifying a segment of the plurality of segments corresponding to the identified format and having a sequence number matching the identified sequence number; loading a segment file corresponding to the specific segment; and returning the segment file to the user device in a response to the request.

A multimedia conference broadcast system may include one or more processors and a memory. The one or more processors may receive video streams and audio streams from participant devices. The one or more processors may transmit, to each of the participant devices, the video streams and the audio streams corresponding to the other devices. The one or more processors may receive a request to broadcast the video streams and the audio streams from one of the participant devices. The one or more processors may generate a composite multimedia stream based on the video streams and the audio streams received from the participant devices. The one or more processors may broadcast the composite multimedia stream to viewer devices that are separate from the participant devices.

Multimedia conference broadcast system

Systems and methods are disclosed for identifying unauthorized presentation of protected content by one or more participants in a media collaboration. In one implementation, a processing device receives one or more content elements, each of the one or more content elements being provided within a media collaboration and associated with one or more users. The processing device identifies an unauthorized presentation of at least one of the one or more content elements within the media collaboration. Based on an identification of the unauthorized presentation, the processing device initiates one or more actions with respect to one or more of the users associated with the at least one of the one or more content elements.

Identifying unauthorized content presentation within media collaborations

Systems and methods are disclosed for detecting when a video stream embedded within a region of another video stream contains copyrighted material. In one implementation, a computer system receives a first video stream and determines that the first video stream comprises a second video stream within a region of the first video stream, using metadata that identifies a set of geometric properties of the region. The computer system obtains the second video stream from the first video stream based on the set of geometric properties of the region, and determines whether the second video stream contains copyrighted material.
