1. An encoding system, comprising:

  • live multimedia content storage configured to store live multimedia content, where the live multimedia content comprises audio data and video data, where the audio data comprises a plurality of audio data samples having an audio data sample duration and the video data comprises a plurality of video frames;

    a processor; and

    a multimedia encoder;

    wherein the multimedia encoder configures the processor to;

    receive live multimedia content;

    generate a timeline using the video data, where the timeline contains a plurality of timestamps, where at least one timestamp in the plurality of timestamps is determined using at least one video frame in the plurality of video frames;

    compute a first time window, where the first time window comprises a first time window duration corresponding to the difference in time between a first timestamp in the timeline and a second timestamp in the timeline;

    align the audio data to the video data using the audio data samples and the timeline by assigning at least one audio data sample to the first time window based upon the number of audio data sample durations that can occur within the first time window duration;

    measure a synchronization value of the aligned audio data to the video data using the timeline;

    realign the audio data to the video data when the synchronization value exceeds a threshold value using the timeline; and

    multiplex the audio data and video data into a container file.
