我对RTSP Stream有疑问。如何在qml中显示来自netwok相机的RTSP流？
设置：
Qt5.10
相机：LunaIP L-DA-5203-V2
操作系统：Windows 7
我测试过的事情：
QML：Camera，MediaPlayer，VideoOutput
到目前为止，我没有找到任何可以用QML解决的问题？
我非常感谢每一个想法。
问候，

有两种方法对我有用：
1。）。在我的public class MessageAdapter extends RecyclerView.Adapter<MessageAdapter.MessageViewHolder>{
private List<Messages> mMessageList;
private FirebaseAuth mAuth;
private View v;
public MessageAdapter(List<Messages> mMessageList){
this.mMessageList = mMessageList;
}
@Override
public MessageViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.message_single_layout,parent,false);
return new MessageViewHolder(v);
}
public class MessageViewHolder extends RecyclerView.ViewHolder{
public TextView messageText;
//public TextView displayName;
//public CircleImageView profileImage;
private final TextView mTimeField;
private final TextView mTextField;
private final FrameLayout mLeftArrow;
private final FrameLayout mRightArrow;
private final RelativeLayout mMessageContainer;
private final LinearLayout mMessage;
private final int mWhite;
private final int mGray;
private final ImageView mImageField;
public MessageViewHolder(View view){
super(view);
//displayName = (TextView) view.findViewById(R.id.display_name_layout);
//messageText = (TextView) view.findViewById(R.id.message);
//profileImage = (CircleImageView) view.findViewById(R.id.message_profile_layout);
mTimeField = (TextView) itemView.findViewById(R.id.time_text);
mTextField = (TextView) itemView.findViewById(R.id.message_text);
mLeftArrow = (FrameLayout) itemView.findViewById(R.id.left_arrow);
mRightArrow = (FrameLayout) itemView.findViewById(R.id.right_arrow);
mMessageContainer = (RelativeLayout) itemView.findViewById(R.id.message_container);
mMessage = (LinearLayout) itemView.findViewById(R.id.message);
mWhite = ContextCompat.getColor(itemView.getContext(), R.color.white);
mGray = ContextCompat.getColor(itemView.getContext(), R.color.gray);
mImageField = (ImageView)itemView.findViewById(R.id.added_image);
}
}
@Override
public void onBindViewHolder(MessageViewHolder viewHolder, int i){
mAuth = FirebaseAuth.getInstance();
String current_user_id = mAuth.getCurrentUser().getUid();
Messages c = mMessageList.get(i);
String from_user = c.getFrom();
String message_type = c.getType();
SimpleDateFormat sfd = new SimpleDateFormat("h:mm a");
String sent_time = sfd.format(c.getTime());
final int color;
if(from_user.equals(current_user_id)){
color = viewHolder.mGray;
viewHolder.mLeftArrow.setVisibility(View.GONE);
viewHolder.mRightArrow.setVisibility(View.VISIBLE);
viewHolder.mMessageContainer.setGravity(Gravity.END);
//viewHolder.mRightArrow.setForegroundGravity(Gravity.TOP | Gravity.RIGHT);
/* LinearLayout.LayoutParams params =
new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.FILL_PARENT);
params.weight = 1.0f;
params.gravity = Gravity.RIGHT;
//viewHolder.messageText.setGravity(Gravity.RIGHT | Gravity.END);
viewHolder.messageText.setTextColor(Color.BLACK);
viewHolder.messageText.setLayoutParams(params);*/
}else{
color = viewHolder.mWhite;
viewHolder.mLeftArrow.setVisibility(View.VISIBLE);
viewHolder.mRightArrow.setVisibility(View.GONE);
viewHolder.mMessageContainer.setGravity(Gravity.START);
/*viewHolder.messageText.setGravity(Gravity.LEFT | Gravity.START);
viewHolder.messageText.setTextColor(Color.BLACK);*/
}
//viewHolder.messageText.setBackgroundResource(R.drawable.message_text_background);
((GradientDrawable) viewHolder.mMessage.getBackground()).setColor(color);
((RotateDrawable) viewHolder.mLeftArrow.getBackground()).getDrawable()
.setColorFilter(color, PorterDuff.Mode.SRC);
((RotateDrawable) viewHolder.mRightArrow.getBackground()).getDrawable()
.setColorFilter(color, PorterDuff.Mode.SRC);
if(message_type.equals("text")){
viewHolder.mTextField.setText(c.getMessage());
viewHolder.mImageField.setVisibility(View.GONE);
}else {
viewHolder.mTextField.setVisibility(View.INVISIBLE);
viewHolder.mImageField.setVisibility(View.VISIBLE);
Picasso.with(viewHolder.mImageField.getContext()).load(c.getMessage()).into(viewHolder.mImageField);
}
viewHolder.mTimeField.setText(sent_time);
}
@Override
public int getItemCount(){
return mMessageList.size();
}
}
中，我使用的是form.ui.qml和MediaPlayer组件
VideoOutput 2。）或我在 MediaPlayer {
id: videoPlayer
source: "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"
muted: true
autoPlay: true
}
VideoOutput {
id: camera1
width: 100
height: 100
anchors.horizontalCenter: parent.horizontalCenter
source: videoPlayer
}
中使用Video组件，如下所示
form.ui.qml
