Nettet闭合GOP以一个被称为IDR(Instantaneous Decoder Refresh,即时解码刷新)的I帧开始。 之所以称之为IDR,是因为当解码器遇到 IDR 帧时,由于在 IDR 之前出现的任何帧都不能用作在该 IDR 之后出现的图片的参考帧,它可以刷新其解码图片缓冲区(Decoded Picture Buffer 或 DPB)。 这就形成了图片序列的彻底中断。 所以,IDR和闭合GOP到 … NettetThe service forces Instantaneous Decoder Refresh (IDR) frames at the insertion points specified in your ESAM XML document for the following output codecs: MPEG-2, MPEG-4 AVC (H.264), or HEVC (H.265).
