The extensions can comprise a custom task that is injected at a specified entry point in the preconfigured workflow, such as after completion of a particular task. The custom task injected into the workflow can perform a variety of processing jobs, such as adding digital rights management (DRM), allowing access to the media content by third parties, injecting advertisements or other content into the media, checking the media content for errors or viruses, and the like. The custom task may also instruct the workflow to delegate access to the media content to external third party services. When the preconfigured workflow reaches the specified entry point, the workflow may be suspended until the custom task is completed, at which point the preconfigured workflow may resume. ## Claims ### Claim 1 A computer implemented method, comprising: enabling access to a plurality of workflows for processing media content, a workflow of the plurality of the workflows including a sequence of processing jobs to be performed on the media content, the sequence of processing jobs including transcoding the media content;

and receiving the media content from the third party after the custom processing tasks have been performed on the media content by the third party. ### Claim 5 (depends on 1) The method of claim 1, wherein preparing the processed media content for distribution further includes: providing, via a content delivery network, the processed media content or a portion of the processed media content to a service provider computing system, wherein the service provider computing system distributes the processed media content to a plurality of users via the content delivery network. ### Claim 6 A non-transitory computer readable storage medium storing one or more sequences of instructions executable by one or more processors to perform a set of operations comprising: enabling access to a plurality of workflows for processing media content, a workflow of the plurality of the workflows including a sequence of processing jobs to be performed on the media content, the sequence of processing jobs including transcoding the media content; selecting, based on attributes of the media content, the workflow for processing the media content; providing processing parameters for the workflow to process the media content, the processing parameters associated with the attributes of the media content or custom processing tasks to be included into the sequence of processing jobs; uploading the media content for processing; and executing the at least one of the plurality of workflows to process the media content. ### Claim 7 (depends on 6) The non-transitory computer readable storage medium of claim 6, further comprising instructions executed by the one or more processors to perform the operations of: determining the custom processing tasks to be injected; suspending the workflow to inject and execute the custom processing tasks; and resuming the workflow upon receiving an indication that the custom processing task have been executed. ### Claim 8 (depends on 6) The non-transitory computer readable storage medium of claim 6, wherein the custom processing tasks further include performing one or more of the following: attaching a watermark to an instance of the media content, the watermark used to uniquely identify the media content, applying digital rights management (DRM) security information to the instance of media content, inserting at least one advertisement into the instance of media content, inspecting the instance of media content for one or more errors, or scanning the instance of media content for potential viruses. ### Claim 9 (depends on 6) The non-transitory computer readable storage medium of claim 6, further comprising instructions executed by the one or more processors to perform the operations of: exposing an application programming interface (API), the API used to specify the custom processing tasks and an entry point in the workflow. ### Claim 10 (depends on 6) The non-transitory computer readable storage medium of claim 6, further comprising instructions executed by the one or more processors to perform the operations of: storing the processed media content, wherein the processed media content is stored locally on a non-transitory storage medium. ### Claim 11 (depends on 6) The non-transitory computer readable storage medium of claim 6, further comprising instructions executed by the one or more processors to perform the operations of: caching the media content at a network edge;
