    • A video coding apparatus may be configured to utilize media extractors in a media extractor track that reference two or more non-consecutive network access layer (NAL) units of a separate track. An example apparatus includes a multiplexer to construct a first track including a video sample comprising NAL units, based on encoded video data, wherein the video sample is included in an access unit, construct a second track including an extractor that identifies at least first one of the NAL units in the video sample of the first track, and wherein the extractor identifies a second NAL unit of the access unit, wherein the first identified NAL unit and the second identified NAL unit are non-consecutive, and include the first track and the second track in a video file conforming at least in part to ISO base media file format. The identified NAL units may be in separate tracks.
    • 视频编码装置可以被配置为使用媒体提取器轨道中的媒体提取器来引用单独轨道的两个或多个非连续网络接入层(NAL)单元。 示例性装置包括多路复用器,用于基于编码的视频数据构建包括包含NAL个单元的视频样本的第一轨道,其中所述视频样本被包括在访问单元中,构建包括提取器的第二轨道,所述提取器至少识别 所述第一轨道的视频样本中的NAL单元,并且其中所述提取器识别所述访问单元的第二NAL单元,其中所述第一识别的NAL单元和所述第二识别的NAL单元是不连续的,并且包括所述第一轨道和 视频文件中的第二轨道至少部分符合ISO基础媒体文件格式。 所识别的NAL单元可以在单独的轨道中。
