Seamless content encoding and transmission
Systems, apparatuses, and methods are described for encoding media content based on an ending delay of first media content and a startup delay of second media content. Second media content may be configured for transmission after first media content in a media content stream. The first media content may be associated with an ending delay corresponding to transmission and/or decoding of frames of the first media content. The second media content may be associated with a starting delay corresponding to transmission and/or decoding of frames of the second media content. The first media content and the second media content may be encoded using different encoding formats. Based on comparing the ending delay and starting delay to a threshold, encoding parameters may be selected, one or more frames may be removed from the first media content and/or the second media content, and/or buffers of one or more devices may be adjusted.
1. A method comprising:
determining, based on comparing a first time period, associated with an end of a first portion of first content encoded at a constant bit rate, and a second time period associated with second content encoded at a variable bit rate, a transition from a first portion of frames of the first content to a second portion of frames of the second content;
encoding, at the constant bit rate, the second portion of frames of the second content; and
outputting for display the first portion of frames before the second content.
2. The method of claim 1 , further comprising:
removing one or more last frames of the first portion of the first content.
3. The method of claim 1 , wherein the outputting for display the first portion of frames before the second content comprises:
causing repeating of at least one of the first portion of frames.
4. The method of claim 1 , wherein the comparing the first time period and the second time period comprises determining that the end of the first portion of the first content will occur before transmission, to a computing device, of the second content is complete.
5. The method of claim 1 , further comprising:
based on the comparing, modifying a size of a video buffer associated with the second content.
6. The method of claim 1 , wherein the comparing the first time period and the second time period comprises determining that the end of the first portion of the first content will occur before a computing device is ready to display the second content.
7. The method of claim 1 , wherein the encoding comprises:
selecting, based on the comparing, a quantization parameter for encoding the second portion of frames.
8. One or more non-transitory computer-readable media storing instructions that, when executed, cause:
determining, based on comparing a first time period, associated with an end of a first portion of first content encoded at a constant bit rate, and a second time period associated with second content encoded at a variable bit rate, a transition from a first portion of frames of the first content to a second portion of frames of the second content;
encoding, at the constant bit rate, the second portion of frames of the second content; and
outputting for display the first portion of frames before the second content.
9. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, cause:
removing one or more last frames of the first portion of the first content.
10. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, cause the outputting for display the first portion of frames before the second content by causing:
causing repeating of at least one of the first portion of frames.
11. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, cause the comparing the first time period and the second time period by causing determining that the end of the first portion of the first content will occur before transmission, to a computing device, of the second content is complete.
12. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, further cause:
based on the comparing, modifying a size of a video buffer associated with the second content.
13. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, cause the comparing the first time period and the second time period by causing determining that the end of the first portion of the first content will occur before a computing device is ready to display the second content.
14. The non-transitory computer-readable media of claim 8 , wherein the instructions, when executed, cause the encoding by causing:
selecting, based on the comparing, a quantization parameter for encoding the second portion of frames.
15. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
determine, based on comparing a first time period, associated with an end of a first portion of first content encoded at a constant bit rate, and a second time period associated with second content encoded at a variable bit rate, a transition from a first portion of frames of the first content to a second portion of frames of the second content;
encode, at the constant bit rate, the second portion of frames of the second content; and
output for display the first portion of frames before the second content.
16. The apparatus of claim 15 , wherein the instructions, when executed by the one or more processors, cause the apparatus to:
remove one or more last frames of the first portion of the first content.
17. The apparatus of claim 15 , wherein the instructions, when executed by the one or more processors, cause the apparatus to output for display the first portion of frames before the second content by causing the apparatus to:
cause repeating of at least one of the first portion of frames.
18. The apparatus of claim 15 , wherein the instructions, when executed by the one or more processors, cause the apparatus to compare the first time period and the second time period by causing the apparatus to determine that the end of the first portion of the first content will occur before transmission, to a computing device, of the second content is complete.
19. The apparatus of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to:
based on the comparing, modify a size of a video buffer associated with the second content.
20. The apparatus of claim 15 , wherein the instructions, when executed by the one or more processors, cause the apparatus to compare the first time period and the second time period by causing the apparatus to determine that the end of the first portion of the first content will occur before a computing device is ready to display the second content.
