x264_frame_pop_unused():获取一个x264_frame_t类型结构体fenc,如果frame.unused[]队列不为空,就调用x264_frame_pop从unused[]队列取出一个现成的;否则就调用x264_frame_new()创建一个新的。 x264_frame_copy_picure():将输入的数据拷贝至fenc。 x264_lookahead_put_frame():将fenc放入lookanead.next.l...
x264编码器和图像色彩空间类型不需要相同。x264编码器是一种开源的视频编码器,用于将视频压缩为H.264格式。它可以处理各种色彩空间类型的视频,包括RGB、YUV等。色彩空间类型是描述图像颜色表示...
x264_encoder_frame_put(); x264_encoder_frame_get(); x264_frame_copy_picture(); 这3个数组和4个函数可以说完成了整个帧的类型的判定问题.这个里面if ,else语句较多,容易使人迷惑.但我们只要把握下面一个观点就可以看清实质:在不对P帧进行编码之前,我们不对B帧进行编码,只是把B帧放进缓冲区(就是前面提...
