Advertisement insertion into media content for streaming

A non-transitory computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving, by an advertisement insertion tool executing by a processing device, a first indication of a start time of where an advertisement is to be inserted into media content;
• receiving, by the advertisement insertion tool, a second indication comprising at least one of an end time of the advertisement or a duration of the advertisement;
• inspecting a first original slice of the media content that contains the media content at the start time to locate a first key frame at or prior to the start time;
• creating a first new slice comprising the media content of the first original slice up to the start time;
• inspecting a second original slice of the media content that contains the media content at the end time to locate a second key frame at or prior to the end time;
• and
• creating a second new slice comprising the media content of the second original slice after the end time until an end of the second original slice,
• wherein the inspecting the first original slice and the inspecting the second original slice comprises:
• reading a container comprising encoded video frames;
• and
• pre-processing the encoded video frames to locate the first key frame and a last frame corresponding to the media content at the start time and to locate the second key frame and a first frame corresponding to the media content after the end time;
• wherein the creating the first new slice comprises creating the first new slice to include the first key frame, any intervening delta frames, and the last frame, and
• wherein the creating the second new slice comprises:
• converting the first frame into a third key frame;
• and
• creating the second new slice to include the third key frame and subsequent frames after the third key frame until an end of the second original slice.

A computing system comprising:

• a memory;
• and
• a processing device, coupled to the memory, wherein the processing device is configured to execute an advertisement insertion tool, wherein the advertisement insertion tool is to:
• receive a first indication of a start time of where an advertisement is to be inserted into media content;
• receive a second indication comprising at least one of an end time of the advertisement or a duration of the advertisement;
• inspect a first original slice of the media content that contains the media content at the start time to locate a first key frame at or prior to the start time;
• create a first new slice comprising the media content of the first original slice up to the start time, wherein when creating the first new slice the processing device is to create the first new slice to include the first key frame, any intervening delta frames, and the last frame;
• inspect a second original slice of the media content that contains the media content at the end time to locate a second key frame at or prior to the end time;
• and
• create a second new slice comprising the media content of the second original slice after the end time until an end of the second original slice,
• wherein when creating the second new slice, the processing device is to:
• convert the first frame into a third key frame;
• and
• create the second new slice to include the third key frame and subsequent frames after the third key frame until an end of the second original slice,
• wherein when inspecting the first original slice and the inspecting the second original slice, the processing device is to:
• read a container comprising encoded video frames;
• and
• pre-process the encoded video frames to locate the first key frame and a last frame corresponding to the media content at the start time and to locate the second key frame and a first frame corresponding to the media content after the end time.
