Abstract

In some embodiments, a method receives a file for transcoding. A timing requirement is associated with the transcoding of the file. The method generates a prediction of a timing estimation based on characteristics of the file and a set of target configurations. A target configuration in the set of target configurations is associated with a transcoding setting. The timing estimation is analyzed for the set of target configurations and the timing requirement to determine a transcoding configuration of a transcoding system. The transcoding configuration of the transcoding system is output to configure the transcoding system to transcode the file. The file is to be transcoded using at least a portion of the set of target configurations based on configuring of the transcoding system.

receiving a file for transcoding, wherein a timing requirement is associated with the transcoding of the file; generating a prediction of a timing estimation based on characteristics of the file and a set of target configurations, wherein a target configuration in the set of target configurations is associated with a transcoding setting; analyzing the timing estimation for the set of target configurations and the timing requirement to determine a transcoding configuration of a transcoding system; and outputting the transcoding configuration to configure the transcoding system to transcode the file, wherein the file is to be transcoded using at least a portion of the set of target configurations based on configuring of the transcoding system; transcoding the file using the set of target configurations; and terminating a transcoding using a target configuration when the timing estimation for the target configurations does not meet the timing requirement.

2 . The method of claim 1 , wherein the timing requirement is a time restriction for transcoding the file.

3 . The method of claim 1 , wherein generating the prediction of the timing estimation comprises:
extracting a feature of the file; and using the feature and a target configuration to predict the timing estimation.

4 . The method of claim 1 , wherein generating the prediction of the timing estimation comprises:
extracting a feature of the file; and using the feature and the set of target configurations to predict the timing estimation for each of the set of target configurations.

5 . The method of claim 1 , wherein a target configuration in the set of target configurations is used by the transcoding system to transcode the file.

6 . The method of claim 1 , wherein analyzing the timing estimation and the timing requirement comprises:
comparing a timing estimation for a target configuration to the timing requirement; and determining whether the file can be transcoded to meet the timing requirement.

7 . The method of claim 6 , wherein analyzing the timing estimation and the timing requirement comprises:
outputting an indication whether the file can be transcoded to meet the timing requirement.

8 . The method of claim 1 , wherein outputting the configuration comprises:
determining one or more of the set of target configurations to use to transcode the file based on the analyzing.

analyzing the first timing estimation and the second timing estimation to determine which of the first timing estimation or the second timing estimation meet the timing requirement; and selecting one of the first timing estimation or the second timing estimation based on which of the first timing estimation or the second timing estimation meet the timing requirement.

16 . The method of claim 15 , wherein:
the first type of computing resource is selected when the first timing estimation and the second timing estimation meet the timing requirement, the second type of computing resource is selected when the first timing estimation does not meet the timing requirement and the second timing estimation meets the timing, and the first type of computing resource is selected when the first timing estimation and the second timing estimation do meet the timing.

17 . The method of claim 1 , wherein generating the prediction of the timing estimation comprises:
generating the prediction of the timing estimation for a portion of the file.

18 . A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:
