Selection and alignment of video segments for adaptive streaming

A computer implemented method, comprising:

• receiving one or more variant segments for decoding and playback, the one or more variant segments including a first variant segment having a first bitrate and second and third variant segments having a second bitrate;
• generating corresponding first, second, and third packetized elementary stream (PES) collections based on at least the first, second, and third variant segments;
• storing the generated first, second, and third PES collections in a processing buffer;
• and
• determining a second in-tolerance splicing location between the first PES collection and the third PES collection based on at least a tolerance offset, in response to a determination of a first out-of-tolerance splicing location between the first PES collection and the second PES location.

A tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving one or more variant segments for decoding and playback, the one or more variant segments including a first variant segment having a first bitrate and second and third variant segments having a second bitrate;
• generating corresponding first, second and third packetized elementary stream (PES) collections based on at least the first, second, and third, variant segments;
• storing the generated first, second, and third PES collections in a processing buffer;
• and
• determining a second in-tolerance splicing location between the first PES collection and the third PES collection based on at least a tolerance offset in response to a determination of a first out-of-tolerance splicing location between the first PES collection and the second PES location.
