Abstract

Disclosed are various embodiments for facilitating uninterrupted playback of video streams using lower quality cached files. A video file corresponding to an entirety of a video content feature encoded at a first quality is obtained. A video stream corresponding to the video content feature encoded at a second quality higher than the first quality is then obtained. The video stream is rendered for playback on a display. In response to detecting an unavailability of the video stream at a particular time in the video content feature, the video file is rendered for playback on the display in place of the video stream and commences at the particular time in the video content feature.

First claim

Therefore, the following is claimed:

1. A system, comprising:
at least one computing device; and
a video player application executable in the at least one computing device, wherein when executed the video player application causes the at least one computing device to at least:
obtain a video stream corresponding to a video content feature encoded at a first quality;
render the video stream for playback on a display;
detect an unavailability of the video stream;
obtain at least a portion of a video file from another computing device on a local network, the video file corresponding to an entirety of the video content feature encoded at a second quality lower than the first quality, wherein the other computing device is configured to at least determine when to obtain the video file based at least in part on a cost to obtain the video file via a network;
detect that an offline mode has been enabled;
render the video file for playback on the display in place of the video stream and commencing at a particular time in the video content feature when the offline mode is enabled; and
resume rendering of the video stream in place of the video file at a later time in the video content feature when the video stream becomes available.

2. The system of claim 1 , wherein when executed the video player application further causes the at least one computing device to at least select the video content feature for predictive caching based at least in part on a viewing history.

3. The system of claim 1 , wherein the video file is obtained before a user expression of interest in playing the video content feature through the video player application.

4. The system of claim 1 , wherein the unavailability of the video stream corresponds to a loss of network connectivity.

5. The system of claim 1 , wherein the other computing device is configured to at least determine whether to obtain the video file based at least in part on a measure of available data storage in a data store accessible to the other computing device.

6. The system of claim 1 , wherein when executed the video player application further causes the at least one computing device to at least:
detect that the at least one computing device has switched from a first type of network connectivity to a second type of network connectivity; and
render the video file for playback on the display in place of the video stream based at least in part on the second type of network connectivity.

7. The system of claim 1 , wherein determining that the video stream is unavailable further comprises determining that obtaining the video stream is associated with an unacceptable cost.

8. A method, comprising:
receiving, by at least one computing device, a user directive to play a video content feature;
obtaining, by the at least one computing device, a video stream corresponding to the video content feature in response to the user directive, the video stream being encoded at a first bitrate;
obtaining, by the at least one computing device, at least a portion of a video file from a client computing device on a local network, the video file corresponding to an entirety of the video content feature encoded at a second bitrate that is lower than the first bitrate, wherein the client computing device is configured to at least determine when to obtain the video file based at least in part on a cost to obtain the video file via a network;
determining, by the at least one computing device, that the video stream is unavailable;
detecting, by the at least one computing device, that an offline mode has been enabled; and
rendering for display, by the at least one computing device, the video file in place of the video stream when the video stream is not available and commencing at a particular time when the offline mode is enabled.

9. The method of claim 8 , further comprising:
detecting that the at least one computing device has switched from a first type of network connectivity to a second type of network connectivity; and
rendering for display, by the at least one computing device, the video file based at least in part on the second type of network connectivity.

10. The method of claim 9 , wherein the first type of network connectivity corresponds to a wireless local area network connection, and the second type of network connectivity corresponds to a cellular network connection.

11. The method of claim 9 , further comprising:
detecting that the at least one computing device has switched from the second type of network connectivity to the first type of network connectivity; and
rendering for display, by the at least one computing device, the video stream based at least in part on the first type of network connectivity.

12. The method of claim 8 , wherein the video file is obtained before the user directive.

13. The method of claim 8 , further comprising determining, by the at least one computing device, that the video stream is not available in response to detecting an interruption in network connectivity.

14. The method of claim 8 , wherein the first bitrate is at least an order of magnitude less than the second bitrate.

15. The method of claim 8 , further comprising rendering for display, by the at least one computing device, the video stream in place of the video file when the video stream becomes available.

16. The method of claim 8 , wherein determining that the video stream is unavailable further comprises determining, by the at least one computing device, that obtaining the video stream is associated with an unacceptable cost.

17. A non-transitory computer-readable medium embodying a program executable in at least one computing device, wherein when executed the program causes the at least one computing device to at least:
obtain a video stream corresponding to a video content feature encoded at a first bitrate;
render the video stream for playback on a display;
detect an interruption in the video stream;
obtain at least a portion of a video file from another computing device on a local network, the video file corresponding to an entirety of the video content feature encoded at a second bitrate lower than the first bitrate, wherein the other computing device is configured to at least determine when to obtain the video file based at least in part on a cost to obtain the video file via a network;
detect that an offline mode has been enabled;
render the video file for playback on the display in place of the video stream and commencing at a particular time in the video content feature when the offline mode is enabled; and
resume rendering of the video stream in place of the video file at a later time in the video content feature when the video stream becomes available.

18. The non-transitory computer-readable medium of claim 17 , wherein the interruption corresponds to a loss of network connectivity.

19. The non-transitory computer-readable medium of claim 17 , wherein when executed the program further causes the at least one computing device to identify the video file to be obtained before receiving a user expression of interest in playing the video content feature.

20. The non-transitory computer-readable medium of claim 17 , wherein the other computing device is configured to predictively cache the video file and at least one other video file.
