Abstract: Techniques are disclosed for multiplexing a dynamic bit-rate video stream with an audio stream received by a client device in a manner that allows the resulting multiplexed stream to be played back without disruption, despite dynamic changes in the bit rate of the video stream that may occur. A content server may stream both a video stream and an audio stream to a client device for playback. The client device may multiplex the video and audio streams prior to them being presented to a playback engine for decoding and playback to a user.

Abstract: Embodiments for changing bit rates in streaming media are provided. As portions of a streaming media file are downloaded for playback, the size of the portion is compared with an expected size determined prior to initiating playback of streaming AV data. The portion of the media file may be padded such that the size of the portion matches the size specified prior to initiating playback of streaming AV data.

Abstract translation: 提供了用于改变流媒体中比特率的实施例。 由于流媒体文件的一部分被下载以便重放，所以将该部分的大小与在启动流式AV数据的回放之前确定的预期大小进行比较。 媒体文件的部分可以被填充，使得该部分的大小与在开始重放流式AV数据之前指定的大小匹配。
