Abstract: Disclosed are various embodiments for seamless insertion of modified media content. In one embodiment, a modified portion of video content is received. The modified portion has a start cue point and an end cue point that are set relative to a modification to the video content to indicate respectively when the modification approximately begins and ends compared to the video content. A video coding associated with the video content is identified. The start cue point and/or the end cue point are dynamically adjusted to align the modified portion with the video content based at least in part on the video coding.

Abstract: Systems and methods described herein provide for novel boundary generation features for interleaving additional content into media content. Media content may be received which includes a video and audio portion. An unencrypted encode of the video portion may be generated. A first set of time stamps for the video portion may be generated using a computer vision algorithm. A second set of time stamps for the video portion may be generated for identifying IDR frames using a first algorithm. A third set of time stamps may be generated to serve as boundaries for interleaving additional content into the media content based on a priority algorithm that uses the first set of time stamps and the second set of time stamps. The video portion may be encoded using the third set of time stamps to determine the IDR frames for the media content.

Abstract: Some implementations include methods for replacing advertisements that have been inserted into a manifest associated with live streaming and may include receiving a request for a manifest from a player to enable a user to watch a live stream of an event. The request may be received at a first time when the live stream is already in progress. The manifest may be generated to include content fragments associated with the live event and advertisements based on first set of selection criteria. The manifest may be sent to the player to enable the user to watch the live stream. A seek back request may be received from the player to enable the user to watch the live stream at a second time earlier than the first time. The manifest may be updated to replace at least one advertisement with a replacement advertisement selected based on second set of selection criteria.

Abstract: Techniques are described for adaptive encoding different portions of media content based on content. Characteristics of GOPs of media content can be determined and used to set encoding parameters for the GOs. The GOPs can be encoded such that one GOP is encoded differently than another GOP if they have different characteristics.

Abstract: Methods and apparatus are described for making broadcast content available as an on-demand asset soon after all of the video fragments of the broadcast content have been made available. As the video fragments of the broadcast content are made available, they are requested and archived. When all of the fragments for the duration of the broadcast content are available (e.g., a live event ends), a VOD-style manifest is generated and the archived fragments are made available for downloading or streaming using the VOD-style manifest.
