store the media data, together with metadata including time indices for each of one or more segments in the media data;

receive user input to generate a primary media content item based on the media data, the user input specifying a start time of the primary media content item;

generate the primary media content item from the media data, starting with the segment of the media data having a time index corresponding to the start time; and

store the primary media content item.

2. The system of claim 1 , wherein the data includes a position of an eye of the user.

3. The system of claim 1 , wherein the media device is one of:

worn by the user; and

attached to clothing worn by the user.

4. The system of claim 1 , wherein the user input includes data specifying a mental state of the user, and the processor is further programmed to:

include the user mental state data in primary metadata associated with the primary media content item.

5. A system comprising:

a media device including a processor and a memory, the memory storing instructions executable by the processor such that the processor is programmed to:

receive, from a video capture device included in the media device, media data;

store the media data, together with metadata including time indices for each of one or more segments in the media data;

receive user input to generate a primary media content item based on the media data, the user input specifying a start time of the primary media content item, wherein the user input includes data specifying a mental state of the user;

generate the primary media content item from the media data, starting with the segment of the media data having a time index corresponding to the start time;

include the user mental state data in primary metadata associated with the primary media content item; and

store the primary media content item;

the system further comprising a computing device including a second processor and a second memory, the second memory storing instructions executable by the second processor such that the second processor is programmed to:

receive, from the processor, the primary media content item and primary metadata;

select, based on the user mental state data, an audio content item; and

generate a secondary media content item, based on the primary media content item and the audio content item.

6. The system of claim 5 , wherein the second processor is further programmed to:

provide a link to allow purchasing a right to include the audio content item in the secondary media content item.

7. The system of claim 5 , wherein the second processor is further programmed to:

provide the secondary media content item to a display device.

8. The system of claim 7 , wherein the second processor is further programmed to:

provide, together with the secondary media content item, a link for purchasing the audio content item.

9. The system of claim 5 wherein the second processor is further programmed to:

receive, from a second media device, a second primary media content item;

determine, based on a second primary metadata associated with the second primary media content item and the primary metadata associated with the primary media content item, that the second primary media content item relates to the primary media content item; and

generate the second secondary media content item based on the primary media content and the second primary media content item.

10. The system of claim 9 , wherein each of the primary metadata associated with the primary media content item and the second primary metadata associated with the second primary media content item include data indicating a respective recording location, and wherein determining that the second primary media content item relates to the primary media content item is based at least in part on the respective recording locations.

11. The system of claim 9 , wherein each of the primary metadata associated with the primary media content item and the second primary metadata associated with the second primary media content item include data indicating a respective identity of a user of the media device and a user of the second media device, wherein determining that the second primary media content item relates to the primary media content item is based at least in part on the respective users.

12. The system of claim 4 , further comprising a computing device including a second processor and a second memory, the second memory storing instructions executable by the second processor such that the second processor is programmed to:

receive, from the processor, the primary media content item and primary metadata;

select, based on the user mental state data, an audio content item;

generate a secondary media content item, based on the primary media content item and the audio content item; and

provide the secondary media content item to a display device.

13. The system of claim 12 , wherein the processor is further programmed to:

provide, together with the secondary media content item, a link for purchasing the audio content item.

14. The system of claim 5 , wherein the processor is further programmed to:

receive, from a sensor included in the media device, sensor data indicating a field of view of a user of the media device, wherein the data includes a position of a portion of a body of the user relative to a position of the media device; and

adjust a field of view of a video capture device in the media device to correspond to the field of view of the user.

15. The system of claim 14 , wherein the portion of the body of the user includes the head of the user.

16. The system of claim 14 , wherein the portion of the body of the user includes the chin of the user.

17. The system of claim 4 , wherein the data includes a position of an eye of the user.

18. The system of claim 1 comprising a computing device including a second processor and a second memory, the second memory storing instructions executable by the second processor such that the second processor is programmed to:

receive, from the media device, the primary media content item including one or more segments, and primary metadata associated with the primary media content item;

receive, from a second media device, a second primary media content item;

determine, based on a second primary metadata associated with the second primary media content item and the primary metadata associated with the primary media content item, that the second primary media content item relates to the primary media content item; and

generate the second secondary media content item based on the primary media content and the second primary media content item.

19. The system of claim 18 , wherein each of the primary metadata associated with the primary media content item and the second primary metadata associated with the second primary media content item include data indicating a respective recording location, and wherein determining that the second primary media content item relates to the primary media content item is based at least in part on the respective recording locations.

20. The system of claim 18 , wherein each of the primary metadata associated with the primary media content item and the second primary metadata associated with the second primary media content item include data indicating a respective identity of a user of the media device and a user of the second media device, wherein determining that the second primary media content item relates to the primary media content item is based at least in part on the respective users.
