MaskOverlayCalculator black screen issue #3405

UnlimitedX · 2022-06-07T20:43:39Z

System information (Please provide as much relevant information as possible)

Android
Solution: SelfieSegmentation
Programming Language and version ( e.g. C++, Python, Java): JAVA

Describe the expected behavior:
I'd like to use the MaskOverlayCalculator node but I get a black screen as output.

My custom graph

I've customized the SelfieSegmentation GPU graph to be able to receive a background video.
I'm sending packets to the graph in Java using the VideoInput java class (solutioncore package).

videoBackgroundInput.setNewFrameListener(textureFrame -> { //Log.d("Segmenter", "New texture frame received"); Packet videoPacket = processor.getPacketCreator().createGpuBuffer(textureFrame); processor.getGraph().addConsumablePacketToInputStream(BACKGROUND_VIDEO_STREAM_NAME, videoPacket, textureFrame.getTimestamp()); videoPacket.release(); });

The background_video is properly displayed if I display it using the RecolorCalculator node. Same for the input_video.
But when I want to use the MaskOverlayCalculator, I get a black screen as output.
Here is the graph below with some comments.

# MediaPipe graph that performs selfie segmentation with TensorFlow Lite on GPU.

## GPU buffer. (GpuBuffer)
input_stream: "input_video"

# Custom Background video
input_stream: "background_video"

# Output image with rendered results. (GpuBuffer)
output_stream: "output_video"

# Throttles the images flowing downstream for flow control. It passes through
# the very first incoming image unaltered, and waits for downstream nodes
# (calculators and subgraphs) in the graph to finish their tasks before it
# passes through another image. All images that come in while waiting are
# dropped, limiting the number of in-flight images in most part of the graph to
# 1. This prevents the downstream nodes from queuing up incoming images and data
# excessively, which leads to increased latency and memory usage, unwanted in
# real-time mobile applications. It also eliminates unnecessarily computation,
# e.g., the output produced by a node may get dropped downstream if the
# subsequent nodes are still busy processing previous inputs.

Hi @UnlimitedX ,
Could you share any reference video w.r.t above issue.

UnlimitedX · 2022-06-09T09:05:13Z

Hi @sureshdagooglecom ,
Thanks for your prompt reply.

I use the Recolor Calculator to check if my videos are adequately provided to the Mediapipe graph.

When the scaled_background_video is activated in the Recolor Calculator, showing the background_video packets are properly injected. (although the video is flipped vertically, no idea why) . The Selfie Segmentation mask is not applied. I don't know why.
[background video]https://noldo.fr/dev/asiaf/2022_06_09_10_40_10.mp4

When the throttled_input_video is active in the recolor calculator, it works as expected. (I blurred my face for privacy reasons and only took a screenshot)

When the Recolor Calculator is disabled and the MaskOverlay Calculator is enabled, I got a black screen.

And I can see such logs in the console:

....

Those logs do not show up when I use the Recolor Calculator.

@sureshdagooglecom

Do you need more details?

UnlimitedX · 2022-06-15T07:50:57Z

Hi @jiuqiant , I'm looking forward to hearing from you :-)

sureshdagooglecom · 2022-06-17T04:37:38Z

Hi @UnlimitedX ,

Have you validated that the mask produced by produced by SelfieSegmentationGpu is useable using the RecolorCalculator? So the only problem is MaskOverlayCalculator?
Please ensure that the RGBA channel produced by SelfieSegmentationGpu matches the channel expected by MaskOverlayCalculator. I see that the default for MaskOverlayCalculator is the RED channel.
3)Please try some constant mask and different two input video streams to gain any insight about non-black output from MaskOverlayCalculator.
4)Please try passing the video stream through a final GL calculator to gain more insight about the output of MaskOverlayCalculator.

Yes it works well.

Please ensure that the RGBA channel produced by SelfieSegmentationGpu matches the channel expected by MaskOverlayCalculator. I see that the default for MaskOverlayCalculator is the RED channel.

Ok thanks, I'm currently doing some tests and I'll keep you updated about the progress.

UnlimitedX · 2022-06-24T12:33:34Z

Hi @sureshdagooglecom
I can confirm the SelfieSegmentationGpu Mask is in the RED channel.

Testing with same inputs

I've tested the MaskOverlayCalculator with the same two inputs for testing purposes, which is the camera input:

node {
  calculator: "MaskOverlayCalculator"
  input_stream: "VIDEO:0:scaled_input_video"
  input_stream: "VIDEO:1:scaled_input_video"
  input_stream: "MASK:segmentation_mask"
  output_stream: "OUTPUT:output_video"
}

I don't have a black screen and the camera is displayed. So I had a non-black output video in this case.

Testing back with background video

When reverting back to my background video, the black screen returns.

node {
  calculator: "MaskOverlayCalculator"
  input_stream: "VIDEO:0:background_video"   <=========
  input_stream: "VIDEO:1:scaled_input_video"
  input_stream: "MASK:segmentation_mask"
  output_stream: "OUTPUT:output_video"
}

Testing with background video + constant mask

I've also tried using the constant mask and the black screen remains.

node {
  calculator: "MaskOverlayCalculator"
  input_stream: "VIDEO:0:background_video"
  input_stream: "VIDEO:1:scaled_input_video"
  input_stream: "CONST_MASK:segmentation_mask_float"  <=========
  output_stream: "OUTPUT:output_video"
}

And the constant is injected like this:

Testing with RecolorCalculator and the background video

Since the RecolorCalculator is working well with the camera input (scaled_input_video) and the segmentation mask, I've tried to replace the camera input by the background_video.
It does not work : the background video is displayed as it, but not segmented using the mask

Video format problem? (RGBA, encoding, or something else ? )

I've tried multiple background videos and the problem remains the same.
So I tried to add a SetAlphaCalculator on the background video in case the Alpha channel was not set at all before injecting the video to the MaskOverlay, but with no effect.
The black screen is still here and I am wondering if the video is not sent correctly to mediapipe, in the right encoding?
Could you suggest to me the right GL calculator to gain more insight about the output of MaskOverlayCalculator?
Any suggestions?

Thanks!

mcclanahoochie · 2022-07-13T18:21:04Z

Hi,

I don't see anything obviously wrong here. It seems the combination of camera and video streams is causing an issue somewhere (but either by itself is OK).

A few other things I can think to check are:

both the camera and video packets sent into the graph have the SAME timestamp, and are both valid each frame
add some logging inside the mask overlay calculator, to make sure Process() is getting called, all packets are present, and finishes properly. example: LOG(INFO)<<"my log";
try simplifying the graph and temporarily remove the flow limiter calculators

UnlimitedX · 2022-07-18T09:49:43Z

Hi @mcclanahoochie,
Thanks for your reply.

I've tried simplifying the graph by removing the flow limiter calculators but the app crashes after a few seconds.

Exited (sigterm)

I've also added some logs following your advice.

And it seems to be stuck before the "process 2 log".

So that means mask_packet.IsEmpty() is true (I added a test directly in the if condition later to make sure it stops here).
With or without the flow limiter, almost the same logs only the frequency is different.

mask_packet should not be empty since it is working well with the RecolorCalculator (I tried again to make sure it's still working).

But from what I understand, the video 1 should be at least displayed :

Nevertheless, I still have a black background.

- both the camera and video packets sent into the graph have the SAME timestamp, and are both valid each frame

Could you please guide me through this process? Since the Camera feed is sent directly into the processor and the background feed is sent through consumable packets I don't know how to check the timestamps at the same place for both. Should I do it in the Process of the MaskCalculator?

How the background feed is sent:

The camera feed is set in the way given in the examples.

Note:
The SetupBackgroundVideo function is called at the very end of the initialization process.

Looking forward to hearing from you!

Hi @mcclanahoochie ,

Have you had a moment to check my previous post?

Thank you very much.

mcclanahoochie · 2022-09-06T21:15:42Z

I don't think having two flow limiter calculators is necessary. Try using a packet cloner for background video instead:

input_stream: "input_video"

input_stream: "background_video"

output_stream: "output_video"

node {
  calculator: "FlowLimiterCalculator"
  input_stream: "input_video"
  input_stream: "FINISHED:output_video"
  input_stream_info: {
    tag_index: "FINISHED"
    back_edge: true
  }
  output_stream: "throttled_input_video"
}

 node {
   calculator: "PacketClonerCalculator"
   input_stream: "TICK:throttled_input_video"
   input_stream: "background_video"
   output_stream: "throttled_background_video"
  # # Try using this setting also:
  # input_stream_handler {
  #   input_stream_handler: "ImmediateInputStreamHandler"
  # }
 }

node {
 calculator: "ImageTransformationCalculator"
 input_stream: "IMAGE_GPU:throttled_background_video"
 output_stream: "IMAGE_GPU:scaled_background_video"
 node_options: {
    [type.googleapis.com/mediapipe.ImageTransformationCalculatorOptions] {
      output_width: 1280
      output_height: 720
    }
  }
}

node {
  calculator: "SelfieSegmentationGpu"
  input_stream: "IMAGE:throttled_input_video"
  output_stream: "SEGMENTATION_MASK:segmentation_mask"
}

node {
  calculator: "MaskOverlayCalculator"
  input_stream: "VIDEO:0:scaled_background_video"
  input_stream: "VIDEO:1:throttled_input_video"
  input_stream: "MASK:segmentation_mask"
  output_stream: "OUTPUT:output_video"
}

The packet cloner will output a packet with every TICK signal.
You may need the ImmediateInputStreamHandler option (try with/without)

I realized I do have not the latest version of mediapipe and the TICK tag was added recently.
So I tried the following configuration based on my packet_cloner_calculator.cc file on my Docker image:

With the ImmediateInputStreamHandler it crashed after 5 seconds of black screen. And without the black screen remained without crashing.

Would you advise updating Mediapipe to its latest version?
If so, do you have any guide on seamlessly doing that? (I am on Docker).

Thanks!

Hi @mcclanahoochie ,
I hope you are doing well.

I've installed the latest version of Mediapipe today and compiled the graph with the exact same code you provided to me.
We still have a black screen with the following logs:

Build file is as follow:

It's working with the ImmediateInputStreamHandler !

Hi @mcclanahoochie ,
I'm reopening this one because I get an error from time to time when starting the graph.
The screen remains black and I can hear the background video, then it crashes a few seconds after. In this case the camera stream doesn't appear.

I spotted the MaskOverlayCalculator / Packet::Getmediapipe::GpuBuffer() error so I thought it was because one stream or the other was starting too quickly and the other stream was not arriving fast enough (the background video was streaming from the network).

Here is what I did without success :

Looking forward to hearing from you!
Thanks :)

The error hints at a video packet being empty.

Try checking for the VIDEO inputs to be not empty , similar to the mask here https://github.com/google/mediapipe/blob/6cdc6443b6a7ed662744e2a2ce2d58d9c83e6d6f/mediapipe/calculators/image/mask_overlay_calculator.cc#L111-L121

Just return ok status if input1_packet or input0_packet is empty.

Hello @UnlimitedX,
We are upgrading the MediaPipe Legacy Solutions to new MediaPipe solutions However, the libraries, documentation, and source code for all the MediapPipe Legacy Solutions will continue to be available in our GitHub repository and through library distribution services, such as Maven and NPM.

You can continue to use those legacy solutions in your applications if you choose. Though, we would request you to check new MediaPipe solutions which can help you more easily build and customize ML solutions for your applications. These new solutions will provide a superset of capabilities available in the legacy solutions. Thank you
