audio frame中文什么意思
伴音帧
例句与用法
- With audio as master media stream and video as slave stream , the scheme makes a comparison between the presentation time stamp of the audio frame and the video frame which are played back recently to synchronize the presentation of video sequence with audio sequence
并以音频流为主媒体流，视频流为从媒体流，比较最近播放的音频帧和视频帧的播放时间标签，调整视频帧的播放持续时间来取得音视频媒体间同步。 - The bridge can continue push the dvb - c transport stream coming from the receive card to the universal media player to display online . in order to be compatible with the data rate in the bridge , the parser must have these functions : identifying the format of each elementary stream ( es ) ; repacketing the es frames or packets into small samples ; timestamping each sample for decoding and delivery by the arithmetic of getting the pts of an audio frame
音视频解析器的设计兼容了桥接器对数据推送的速率,在该解析器中通过“解析音视频基本流”算法来识别出每一个流的格式、每一帧数据,并对这些数据重新打包成一个个数据sample ,再通过“音频pts的获取”算法给这些sample打上正确的“ directshow ”时间戳,最后在相应的输出pin上进行发送。 - The scheme adjusts the audio frame length without impairing audio quality according to the occupied level of audio playout buffer and changes the playout frame rate of video according to the occupied level of video playout buffer to achieve intra - media synchronization of audio stream and video stream
算法分别根据音频和视频播放缓冲区的占用水平，在不影响音频播放质量的情况下调整音频帧的长度，实现音频流媒体内同步；通过改变视频流的播放帧率达到视频流媒体内同步。
