Methods and apparatus for automatic media file transcoding

A computer program product, comprising a tangible machine-readable storage medium having encoded therein executable code of one or more software programs, wherein the one or more software programs when executed by at least one processing device perform the following steps:

• obtaining, by a transcoding media system, at least one input media file having an input file format and encoded with a codec of a first type;
• automatically determining, by the transcoding media system, a plurality of output media file formats that the input media file is to be transcoded into, wherein the determining comprises:
• (i) obtaining statistics for files stored in a storage system associated with the transcoding media system, (ii) generating a set of popular output media file formats and a set of trending media output media file formats based on the statistics, and (iii) combining the sets into a single list, wherein the statistics comprise statistics of previously transcoded files and statistics of one or more trending media file formats for previously downloaded files over a given period of time;
• automatically selecting one or more transcoding algorithms for transcoding the at least one input media file into the plurality of output media file formats, wherein the selecting is based at least in part on an unsupervised machine learning technique that identifies files previously transcoded by the transcoding media system that are proximally similar to the at least one input media file;
• generating a list of pairs, each pair comprising one of the plurality of output media file formats and one of the one or more transcoding algorithms;
• dynamically prioritizing the list of pairs based at least in part on the set of popular output media file formats and the set of trending media output media file formats;
• and
• transcoding, based at least in part on said prioritizing, the at least one input media file into a plurality of transcoded output media files having the determined one or more output media file formats, wherein the transcoding uses at least one codec of a second type that is different than the first type.

A system, comprising:

• a memory;
• and
• at least one processing device, coupled to the memory, operative to implement the following steps:
• obtaining, by a transcoding media system, at least one input media file having an input file format and encoded with a codec of a first type;
• automatically determining, by the transcoding media system, a plurality of output media file formats that the input media file is to be transcoded into, wherein the determining comprises:
• (i) obtaining statistics for files stored in a storage system associated with the transcoding media system, (ii) generating a set of popular output media file formats and a set of trending media output media file formats based on the statistics, and (iii) combining the sets into a single list, wherein the statistics comprise statistics of previously transcoded files and statistics of one or more trending media file formats for previously downloaded files over a given period of time;
• automatically selecting one or more transcoding algorithms for transcoding the at least one input media file into the plurality of output media file formats, wherein the selecting is based at least in part on an unsupervised machine learning technique that identifies files previously transcoded by the transcoding media system that are proximally similar to the at least one input media file;
• generating a list of pairs, each pair comprising one of the plurality of output media file formats and one of the one or more transcoding algorithms;
• dynamically prioritizing the list of pairs based at least in part on the set of popular output media file formats and the set of trending media output media file formats;
• and
• transcoding, based at least in part on said prioritizing, the at least one input media file into a plurality of transcoded output media files having the determined one or more output media file formats, wherein the transcoding uses at least one codec of a second type that is different than the first type.
