我使用的sdk版本是8.04
我为了实现实时解码h264码流(由YUV420P编码而成)，在软件中创建了一条pipline：
sprintf(cmd, "appsrc format=GST_FORMAT_TIME is-live=true do-timestamp=true block=true name=appsrc ! queue \
! h264parse \
! video/x-h264, parsed=true, stream-format=byte-stream, alignment=au \
! v4l2h264dec \
! video/x-raw, format=(string)I420 \
! appsink name=appsink drop=true async=false sync=false buffer-list=true enable-last-sample=false wait-on-eos=false max-buffers=50 \n");
GstElement *pipeline;
pipeline = gst_parse_launch(cmd, NULL);
我在循环中，通过gst_app_src_push_buffer往 ’appsrc‘插件中写入h264码流数据（每次写入一个nalu）。
循环外，我通过g_signal_connect(appsink, "new-sample", G_CALLBACK(new_sample_callback), NULL);将new_sample_callback绑定到'appsink'的信号“new-sample‘，以获取解码后的数据。
但是打印了一些重复类似的log：

解码后的数据也不是我想要的YUV420P，请问是我的pipline设计有问题吗，还是v4l2h264dec 插件本身有问题？
