TDA4VE-Q1: SDK0901 gstreamer编码如何控制IDR帧频率

Part Number: TDA4VE-Q1

SDK0806 gstreamer v4l2h264enc控件有i-period和gop-size参数,可以控制输出流的IDR帧频率,但是升级到SDK0901后取消了这两个参数(i-period,gop-size)。查阅论坛,通过extra-controls可以设置i帧频率,例如:v4l2h264enc extra-controls="enc,h264_i_frame_period=3",但是IDR周期我不知道怎么设置

下图是SDK0806 v4l2h264enc的参数列表

下图是SDK0901 v4l2h264enc的参数列表

请问SDK0901 gstreamer v4l2h264enc控件如何控制gop-size
