Synchronized out-of-order live video encoding for reduced latency

A computer-implemented method comprising:

• receiving a first encoded video, that is in a coded order that is different than a display order, at a content delivery service from a contribution encoder;
• performing, in the coded order, a decode of the first encoded video by the content delivery service to generate a decoded video in the coded order;
• performing, in the coded order, an encode of the decoded video by an encoder of the content delivery service to generate a second encoded video in the coded order without waiting on a reordering of the decoded video into the display order in response to a maximum number of bidirectional predicted picture frames used in the encoder of the content delivery service not being greater than a maximum number of bidirectional predicted picture frames used in the contribution encoder;
• and
• transmitting the second encoded video to a client device.

A system comprising:

• a content delivery service implemented by a first one or more electronic devices, the content delivery service including instructions that upon execution cause the first one or more electronic devices to perform operations comprising:
• receiving a first encoded video, that is in a coded order that is different than a display order, from a contribution encoder,
• performing, in the coded order, a decode of the first encoded video to generate a decoded video in the coded order, and
• performing, in the coded order, an encode of the decoded video by an encoder of the content delivery service to generate a second encoded video in the coded order without waiting on a reordering of the decoded video into the display order in response to a maximum number of bidirectional predicted picture frames used in the encoder of the content delivery service not being greater than a maximum number of bidirectional predicted picture frames used in the contribution encoder;
• and
• a packaging service implemented by a second one or more electronic devices, the packaging service including instructions that upon execution cause the second one or more electronic devices to perform operations comprising transmitting the second encoded video to a client device.
