Live streaming video processing

A method comprising:

• using at least one microprocessor to execute computer executable instructions stored on at least one non-transitory computer readable medium to perform the following acts:
• receiving segments of a live video stream of a live video broadcasting in association with a request to process the live video stream;
• generating an instruction graph for the live video stream based on predetermined criteria, the instruction graph defining a workflow for processing the live video stream in real time, the workflow comprising a plurality of processing groups, wherein the plurality of processing groups respectively process copies of the segments in parallel and respectively output different formatted versions of the live video stream, wherein the plurality of processing groups respectively comprise sets of services configured to respectively perform different video processing tasks;
• and
• processing the live video stream based on the instruction graph, including:
• generating the copies of the segments;
• executing the plurality of processing groups to respectively process the copies of the segments in parallel based at least in part on the instruction graph;
• identifying a processing failure associated with a service of a set of services of one of the plurality of processing groups during the processing of an Nth segment of the segments, where N is an integer;
• and
• re-executing the one of the plurality of processing groups to re-process the Nth segment in response to the identifying the processing failure associated with the service of the first set of the services while maintaining execution of other ones of the plurality of processing groups.

A non-transitory computer-readable storage medium comprising computer-readable instructions that, in response to execution, cause a computing system to perform operations, comprising:

• receiving segments of a live video stream of a live video broadcasting in association with a request to process the live video stream;
• generating an instruction graph for the live video stream based on predetermined criteria, the instruction graph defining a workflow for processing the live video stream in real time, the workflow comprising a plurality of processing groups, wherein the plurality of processing groups respectively process copies of the segments in parallel and respectively output different formatted versions of the live video stream, and wherein the plurality of processing groups respectively comprise sets of services to respectively perform different video processing tasks;
• and
• processing the live video stream based on the instruction graph, including:
• generating the copies of the segments;
• executing the plurality of processing groups to respectively process the copies of the segments in parallel based at least in part on the instruction graph;
• identifying a processing failure associated with a service of a set of services of one of the plurality of processing groups during the processing of an Nth segment of the segments, where N is an integer;
• and
• re-executing the one of the plurality of processing groups to re-process the Nth segment in response to the identifying the processing failure associated with the service of the first set of the services while maintaining execution of other ones of the plurality of processing groups.
