Improving streaming video quality in lossy network conditions

A method comprising:

• determining, using one or more processors, a size of a sliding frame window for a video stream, the size of the sliding frame window representing a minimum separation between reference frames and corresponding inter frames, wherein the size of the sliding frame window is determined based at least on message timing data associated with one or more indications of video frame loss or non-reception, wherein determining the size of the sliding frame window comprises:
• receiving an indication that a previously transmitted video frame has been determined to be lost or is associated with lost data packets;
• and
• determining a corresponding count representing a number of video frames transmitted after transmission of the previously transmitted video frame and before reception of at least one message comprising the indication;
• wherein the size of the sliding frame window is determined using at least the corresponding count;
• and
• encoding, using the one or more processors, a plurality of video frames of the video stream according to the size of the sliding frame window, such that a separation between a reference frame and a corresponding inter frame is greater than or equal to the size of the sliding frame window.

A system, comprising:

• an application programming interface (API) to interface with an application executed using one or more processors, the API to cause the one or more processors to:
• determine a size of a sliding frame window for a video stream, wherein the size of the sliding frame window represents a minimum separation between reference frames and corresponding inter frames, wherein the size of the sliding frame window is determined based at least on message timing data associated with one or more indications of video frame loss or non-reception, wherein determining the size of the sliding frame window comprises:
• receiving an indication that a previously transmitted video frame has been determined to be lost or is associated with lost data packets;
• and
• determining a corresponding count representing a number of video frames transmitted after transmission of the previously transmitted video frame and before reception of at least one message comprising the indication;
• wherein the size of the sliding frame window is determined using at least the corresponding count;
• and
• encode a plurality of video frames of the video stream according to the size of the sliding frame window, wherein a separation between a reference frame and a corresponding inter frame, is greater than or equal to the size of the sliding frame window.
