Techniques and solutions are described for executing a video processing task. A video processing task is received that includes one or more operations to be performed on a digital video file and an identifier of the digital video file. The video processing task is divided into subtasks of operations to be performed on fragments of the video, such as fragments having a particular duration. The duration can correspond to a duration used for video streaming Compared with video processing that is performed as a single task, disclosed techniques can provide improved fault tolerance, as only failed tasks need to be reprocessed. Video processing subtasks can be distributed to a plurality of workers, which can further improve fault tolerance, and can increase the computing power available for video processing, including allowing for the use of heterogenous or unreliable workers.

Processing of video operations as subtasks for video fragments

A method and system for uploading a media file container from a first device to a second device are described herein, including receiving an instruction to upload the media file container and in response, reading a metadata box of the media file container to locate a track box containing information about audio data, including a size and a location of the audio data, in a media data box of the media file container, identifying the audio data in the media data box using the information from the track box, packaging the identified audio data from the media data box into an audio byte stream separate from the media data box, and uploading the audio byte stream to the second device prior to completing upload of the media file container.

Self-driven adaptive upload

A method and system for uploading a media file container from a first device to a second device are described herein, including receiving an instruction to upload the media file container and in response, reading a metadata box of the media file container to locate a track box containing information about video data in a media data box, identifying sample frames of the video data throughout a duration of the video data in the media data box using information from the track box, packaging the identified sample frames, and uploading the packaged sample frames of the video data prior to completing upload of the media file container.

Described herein are various technologies pertaining to delivery of token-authenticated encrypted data. Content descriptor(s) (e.g., playlist(s)) can be modified to facilitate exchange of a token for a decryption key for browser(s) that do not provide logic to manage a flow of the token.
