Abstract

An approach provides distributed editing and storage of digital media. Video information is retrieved during recording of the video information to a video file. The video information is edited during the recording of the video information. An index file for the media is generated during the recording of the media, wherein the index file include indices for decoding the media; and periodically updating the index file throughout the recording of the media. After completion of the recording of the media, another index file is generated corresponding to the media for inclusion into the media file.

Claims

1. A method for editing digital media, the method comprising:

retrieving media during recording of the media to a media file; and

editing the media during the recording of the media.

2. A method according to claim 1, further comprising:

generating an index file for the media during the recording of the media, wherein the index file include indices for decoding the media; and

periodically updating the index file throughout the recording of the media.

3. A method according to claim 2, wherein the digital media represents video information that is encoded according to a Group of Pictures (GOP) format.

4. A method according to claim 3, further comprising:

after completion of the recording of the media, generating another index file corresponding to the media for inclusion into the media file.

5. A method according to claim 3, further comprising:

storing the media file in a layered cache including a compressed section for storing encoded media and a decompressed section for storing a decompressed video frame associated with the media.

6. A method according to claim 5, wherein the layered cache interacts with a plurality of caching threads including a playback caching thread for caching the media file for playback, and a riddling thread supporting scrubbing of the media.

7. A method according to claim 1, further comprising:

forwarding the media file to an object store configured to provide virtual digital asset management of content for operation with a workflow application, wherein the workflow application includes proxy viewing, logging and editing, craft editing, and delivery of the content.

8. A method according to claim 1, wherein the media is output from a live feed.

9. An apparatus for editing digital media, the apparatus comprising:

a communication interface configured to retrieve media during recording of the media to a media file; and

a processor coupled to the communication interface and configured to edit the media during the recording of the media by using a proxy of the media.

10. An apparatus according to claim 9, where the processor is further configured to generate an index file for the media during the recording of the media, wherein the index file include indices for decoding the media, and the index file is periodically updated throughout the recording of the media.

11. An apparatus according to claim 10, wherein the digital media represents video information that is encoded according to a Group of Pictures (GOP) format.

12. An apparatus according to claim 11, wherein the processor is further configured to generate another index file corresponding to the media for inclusion into the media file, after completion of the recording of the media.

13. An apparatus according to claim 11, further comprising:

a memory configured to store the media file as a layered cache including a compressed section for storing encoded media and a decompressed section for storing a decompressed video frame associated with the media.

14. An apparatus according to claim 13, wherein the layered cache interacts with a plurality of caching threads including a playback caching thread for caching the media file for playback, and a riddling thread supporting scrubbing of the media.

15. An apparatus according to claim 9, wherein the media file is forwarded to an object store configured to provide virtual digital asset management of content for operation with a workflow application, wherein the workflow application includes proxy viewing, logging and editing, craft editing, and delivery of the content.

16. An apparatus according to claim 9, wherein the media is output from a live feed.

17. A method for processing media, the method comprising:

determining existence of a supplemental index file corresponding to a media stream, wherein the supplemental index file is generated during streaming and specifies decoding of the media stream for playback at asynchronous points in the media stream;

based on the determination, playing back the media stream according to a selected supplemental index of the supplemental index file; and

generating an index file separate from the supplemental index file upon completion of the streaming.

18. A method according to claim 17, further comprising:

selectively discarding the supplemental index file.

19. A method according to claim 18, wherein the media stream represents video information that is encoded according to a Group of Pictures (GOP) format.

20. A method according to claim 17, further comprising:

requesting, during the streaming, a particular portion of the media stream based on the selected supplemental index

21. A method according to claim 17, further comprising:

receiving the particular portion of the media stream; and

caching the particular portion.

22. A method according to claim 17, wherein the media stream is received from a virtual asset manager configured to access content from a plurality of content providers.

23. A method according to claim 17, wherein the media stream represents a live feed.
