Methods and systems for fault tolerant video packaging
Disclosed are various systems and methods for fault tolerant video packaging and transmission. A video packager may receive one or more video content transmissions from a transcoder, and may identify deficient segments, packets, or other portions of the video content transmission. The video packager may also maintain or have access to a default video output that is free of the identified deficiencies. For example, the default video output can include one or more segments of video data comprising a blank or solid color frame, or a still image. The deficient data may be determined based on validation parameters. If the validation parameters are satisfied, the received data is packaged and transmitted. Otherwise, the default video output is packaged to replace deficient portions, and transmitted instead of the received video content.
1 . A method comprising:
receiving, by a video packager, a first portion of a video stream;
determining, by the video packager, that the first portion of the video stream does not conform to one or more validation parameters; and
