Systems and methods for encoding video content
Systems and methods for encoding a plurality of alternative streams of video content using multiple encoders in accordance with embodiments of the invention are disclosed. An encoding system includes multiple encoders. Each of the encoders receives a source stream of video content that is divided into portions. Each of the encoders generates portions of the plurality of alternative streams from the portions of the source stream. The portions of the alternative streams generated by a particular encoder are stored in a container for the particular encoder. Each encoder also generates index information for the portion of the alternative stream generated by the encoder that is stored in a manifest for the encoder.
1. A method of encoding a plurality of alternative streams of video content from a source stream of video content using a plurality of encoders in an encoding system, the method comprising:
receiving a plurality of portions of the source stream of video content;
instantiating the plurality of encoders; and
encoding the plurality of portions of the source stream of video content such that each portion of the source stream is encoded by one of the plurality of encoders,
wherein different portions of the source stream are encoded by different encoders of the plurality of encoders;
storing the different portions of the source stream in a container for the encoded stream;
generating index information for the encoded stream; and
storing the index information for the encoded stream in the container for the encoded stream.
2. The method of claim 1 , wherein the encoded stream comprises a particular set of parameters.
3. The method of claim 2 , wherein the particular set of parameters comprises a particular maximum bitrate.
4. The method of claim 2 , wherein the particular set of parameters comprises at least one selected from the group consisting of aspect ratio, frame rate, and resolution.
5. The method of claim 1 , further comprising causing the encoder encoding each of the portions to encode multiple times to create a plurality of alternative encoded streams each having a different set of parameters.
6. The method of claim 5 , wherein at least two alternative encoded streams have a same maximum bitrate and at least one other parameter that is different.
7. The method of claim 5 , further comprising generating index information for each of the plurality of alternative encoded streams.
8. The method of claim 1 , wherein the index information is stored in a manifest.
9. The method of claim 8 , wherein the manifest further includes information indicating when at least one of the encoded portions is available for streaming.
10. An encoding system for encoding a source stream of video content comprising:
at least one processor;
memory accessible by the at least one processor; and
instructions stored in the memory that when read by the at least one processor direct the processor to:
receive a plurality of portions of the source stream of video content;
instantiate the plurality of encoders; and
encode the plurality of portions of the source stream of video content such that each portion of the source stream is encoded by one of the plurality of encoders,
wherein different portions of the source stream are encoded by different encoders of the plurality of encoders;
store the different portions of the source stream in a container for the encoded stream;
generate index information for the encoded stream; and
store the index information for the encoded stream in the container for the encoded stream.
11. The system of claim 10 , wherein the encoded stream comprises a particular set of parameters.
12. The system of claim 11 , wherein the particular set of parameters comprises a particular maximum bitrate.
13. The system of claim 11 , wherein the particular set of parameters comprises at least one selected from the group consisting of aspect ratio, frame rate, and resolution.
14. The system of claim 10 , wherein the instructions further direct the processor to cause the encoder encoding each of the portions to encode multiple times to create a plurality of alternative encoded streams each having a different set of parameters.
15. The system of claim 14 , wherein at least two alternative encoded streams have a same maximum bitrate and at least one other parameter that is different.
16. The system of claim 14 , wherein the instructions further direct the processor to generate index information for each of the plurality of alternative encoded streams.
17. The system of claim 10 , wherein the index information is stored in a manifest.
18. The system of claim 17 , wherein the manifest further includes information indicating when at least one of the encoded portions is available for streaming.
