Subtitle-based rewind for video display
A processing device can partition a video presentation into segments, wherein the beginning of each of the segments corresponds to when a specific subtitle would be displayed. In some examples, a system can be configured so that a subtitle in a selected language can be displayed at that point, even if subtitles in a different language are being displayed by default. A user can thus activate a rewind control for a video playback device or application and obtain a translation of the dialog at that point into the user's preferred language. The subtitle-based rewind feature can be implemented, as examples, in a client playback application on a playback device for streaming video, as part of a video streaming provider's back-end services deployed in a cloud network, or by a combination of the two.
1. A system comprising:
a processing device; and
a memory device including instructions that are executable by the processing device for causing the processing device to perform operations comprising:
receiving media data and subtitle text corresponding to the media data;
configuring varying time intervals for a rewind input to be applied to the media data to correspond to display intervals that vary for subtitles in the subtitle text based on subtitle timestamps in the subtitle text;
displaying the media data for a current subtitle timestamp on a playback device; and
displaying, based on the rewind input, the media data for a previous subtitle timestamp on the playback device.
2. The system of claim 1 wherein the operations further comprise:
accessing a translation preference indicator; and
displaying a subtitle from the subtitle text in a translation language corresponding to the translation preference indicator while displaying the media data for the previous subtitle timestamp.
3. The system of claim 2 , wherein the operations further comprise:
accessing a stored default subtitle language indicator; and
displaying a subtitle from the subtitle text in a default language corresponding to the stored default subtitle language indicator while displaying the media data for the current subtitle timestamp.
4. The system of claim 1 , wherein the varying time intervals for the rewind input to be applied to the media data are configured by a software loop running in at least one pod of a cloud-computing network.
5. The system of claim 4 , wherein the at least one pod receives the subtitle text in a subrip text file from a content delivery network server that includes at least a portion of the media data.
6. The system of claim 5 , wherein the at least one pod is communicatively coupled to an API server for a cluster including the at least one pod, and wherein the software loop uses the API server to configure the varying time intervals for the rewind input.
7. A method comprising:
receiving, by a processing device, media data and subtitle text corresponding to the media data;
configuring, by the processing device, varying time intervals for a rewind input to be applied to the media data to correspond to display intervals that vary for subtitles in the subtitle text based on subtitle timestamps in the subtitle text;
displaying, by the processing device, the media data for a current subtitle timestamp;
monitoring, by the processing device, the rewind input of a playback device while displaying the media data for the current subtitle timestamp; and
displaying, by the processing device based on the rewind input, the media data for a previous subtitle timestamp.
8. The method of claim 7 further comprising:
accessing a translation preference indicator; and
displaying a subtitle from the subtitle text in a translation language corresponding to the translation preference indicator while displaying the media data for the previous subtitle timestamp.
9. The method of claim 8 , further comprising:
accessing a stored default subtitle language indicator; and
displaying a subtitle from the subtitle text in a default language corresponding to the stored default subtitle language indicator while displaying the media data for the current subtitle timestamp.
10. The method of claim 8 , wherein the varying time intervals for the rewind input to be applied to the media data are configured by a software loop running in at least one pod of a cloud-computing network.
11. The method of claim 10 , wherein the at least one pod receives the subtitle text in a subrip text file from a content delivery network server that includes at least a portion of the media data.
12. The method of claim 10 , wherein the at least one pod is communicatively coupled to an API server for a cluster including the at least one pod, and wherein the software loop uses the API server to configure the varying time intervals for the rewind input.
13. A non-transitory computer-readable medium comprising program code that is executable by a processing device for causing the processing device to:
receive media data and subtitle text corresponding to the media data;
configure varying time intervals for a rewind input to be applied to the media data to correspond to display intervals that vary for subtitles in the subtitle text based on subtitle timestamps in the subtitle text;
display the media data for a current subtitle timestamp;
monitor the rewind input of a playback device while displaying the media data for the current subtitle timestamp; and
display, based on the rewind input, the media data for a previous subtitle timestamp.
14. The non-transitory computer-readable medium of claim 13 , wherein the program code is executable for causing the processing device to:
access a translation preference indicator; and
display a subtitle from the subtitle text in a translation language corresponding to the translation preference indicator while displaying the media data for the previous subtitle timestamp.
15. The non-transitory computer-readable medium of claim 14 , wherein the program code is executable for causing the processing device to:
accessing a stored default subtitle language indicator; and
displaying a subtitle from the subtitle text in a default language corresponding to the stored default subtitle language indicator while displaying the media data for the current subtitle timestamp.
16. The non-transitory computer-readable medium of claim 14 , wherein the varying time intervals for the rewind input to be applied to the media data are configured by a software loop running in at least one pod of a cloud-computing network.
17. The non-transitory computer-readable medium of claim 16 , wherein the at least one pod receives the subtitle text in a subrip text file from a content delivery network server that includes at least a portion of the media data.
18. The non-transitory computer-readable medium of claim 16 , wherein the at least one pod is communicatively coupled to an API server for a cluster including the at least one pod, and wherein the software loop uses the API server to configure the varying time intervals for the rewind input.
