Reading MJPEG stream from Flask server with OpenCV (Python)

I'm generating a MJPEG stream using Flask and flask-restful. For reasons, I want to catch this stream in another Python program, for which I use OpenCV(3).Problem is that the first frame that is requested comes in well. On the other hand, the second frame that is requested (after a delay) is not received properly, and throws the error:

[mpjpeg @ 0000017a86f524a0] Expected boundary '--' not found, instead found a line of 82 bytes

Multiple times.

I believe this happens because the boundary of a frame is set manually. I will put the offending code below.

MJPEG Stream generation:

## Controller for the streaming of content.class StreamContent(Resource): @classmethod def setVis(self, vis): self.savedVis = vis def get(self): return Response(gen(VideoCamera(self.savedVis)), mimetype='multipart/x-mixed-replace; boundary=frame')## Generate a new VideoCamera and stream the retrieved frames. def gen(camera): frame = camera.getFrame() while frame != None: yield (b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n') time.sleep(0.07) frame = camera.getFrame()## Allows for the reading of video frames.class VideoCamera(object): def __init__(self, vis): #object we retrieve the frame from. self.vis = vis ## Get the current frame. def getFrame(self): image = self.vis.mat_frame_with_overlay # We are using Motion JPEG, but OpenCV defaults to capture raw images, # so we must encode it into JPEG in order to correctly display the # video/image stream. ret, jpeg = cv2.imencode('.jpg', image) return jpeg.tobytes()

MJPEG Stream retrieval:

"""Get a single frame from the camera.""" class Image(Resource): def get(self): camera = VideoCamera() return Response(camera.getSingleFrame(), mimetype='image/jpeg')"""Contains methods for retrieving video information from a source."""class VideoCamera(object): def __del__(self): self.video.release() @classmethod def setVideo(self, video): self.video = video ## Get the current frame. def getSingleFrame(self): self.startVideoFromSource(self.video) ret, image = self.video.read() time.sleep(0.5) ret, image = self.video.read() # We are using Motion JPEG, but OpenCV defaults to capture raw images, # so we must encode it into JPEG in order to correctly display the # video/image stream. ret, jpeg = cv2.imencode('.jpg', image) self.stopVideo() return jpeg.tobytes() def stopVideo(self): self.video.release()

Matlab Animation

There is a two simple way to animate plot in Matlab. First is by standard plot function – you can employ it in a way that the animation looks smooth.

Second, there are special functions getframe and movie, which allows us to capture sequence of plots and then play them. Let’s look at an example:

So, we have matlab function file named kp_animation, with return value M and input arguments –…

How to stream live video frames from client to flask server and back to the client?

I am trying to build a client server architecture where I am capturing the live video from user's webcam using getUserMedia(). Now instead of showing video directly in <video> tag, I want to send it to my flask server, do some processing on frames and throw it back to my web page.

I have used socketio for creating a client-server connection.This is the script in my index.html. Please pardon my mistakes or any wrong code.

<div id="container"> <video autoplay="true" id="videoElement"> </video></div>

<script type="text/javascript" charset="utf-8"> var socket = io('http://127.0.0.1:5000'); // checking for connection socket.on('connect', function(){ console.log("Connected... ", socket.connected) }); var video = document.querySelector("#videoElement"); // asking permission to access the system camera of user, capturing live // video on getting true. if (navigator.mediaDevices.getUserMedia) { navigator.mediaDevices.getUserMedia({ video: true }) .then(function (stream) { // instead of showing it directly in <video>, I want to send these frame to server //video_t.srcObject = stream //this code might be wrong, but this is what I want to do. socket.emit('catch-frame', { image: true, buffer: getFrame() }); }) .catch(function (err0r) { console.log(err0r) console.log("Something went wrong!"); }); } // returns a frame encoded in base64 const getFrame = () => { const canvas = document.createElement('canvas'); canvas.width = video_t.videoWidth; canvas.height = video_t.videoHeight; canvas.getContext('2d').drawImage(video_t, 0, 0); const data = canvas.toDataURL('image/png'); return data; } // receive the frame from the server after processed and now I want display them in either // <video> or <img> socket.on('response_back', function(frame){ // this code here is wrong, but again this is what something I want to do. video.srcObject = frame; });</script>

In my app.py -

from flask import Flask, render_templatefrom flask_socketio import SocketIO, emitapp = Flask(__name__)socketio = SocketIO(app)@app.route('/', methods=['POST', 'GET'])def index(): return render_template('index.html')@socketio.on('catch-frame')def catch_frame(data): ## getting the data frames ## do some processing ## send it back to client emit('response_back', data) ## ??if __name__ == '__main__': socketio.run(app, host='127.0.0.1')

I also have thought to do this by WebRTC, but I am only getting code for peer to peer.

So, can anyone help me with this?Thanks in advance for help.
