Can I get video stream from a tcpip port (ArDrone) to a Matlab figure? Latest activity Commented on by on 5 Jan 2017I am trying to obtain video from an IP webcam in particular that HD camera on ARdrone parrot 2.0, I can get the video stream either with MPEG4.2 soft encoder or with H264-like codec or with MJPEG-like codec and is sent by a tcpip port by the drone.The point is that, I have already been able to display this video stream on ffplay (external program to Matlab) using win7, but I would like to save video in a variable on Matlab in order to use image proccesing with it and control the drone depending on what "it's seeing".I have already looked up for this matter and have not found anything illuminating. So I will be very grateful if any of you know how to get this image straight from the tcpip port or even from ffplay program. No products are associated with this question. There is a possibility that the situation has changed in the last two releases, but if not:In R2014a and earlier (and perhaps it is still the case), there is no built-in facility for decoding streaming video, other than whatever can be handled by the GigE Vision Standard.

For winvideo, whether directly connected cards or USB, the acquisition is frame by frame, complete frames. IP cameras other than perhaps GigE Vision compliant are handled by fetching individual frames, not by streaming video.The Computer Vision toolkit does support H.264, but at least up to R2014a, only from files, not streaming from a device.The only option I am aware of at the moment (other than whatever GigE Vision can handle) is that on MS Windows you can get programs that decode streaming video and which have ActiveX / Component Object (COM) interfaces that permit the output to be accessed as frames. I don't know if any of those offer a virtual Winvideo to make it even easier. I have been dealing with the same problem.The solution I came with is to use ffmpeg to obtain images instead of the video stream. Basically, there are images continually being saved in a specified folder and, with Matlab, you can read and show them (it will be the same as if you were streaming) or process them.

You will get rid of the lag that the stream has and you can increase the fps. I've just uploaded a submission that supports streaming h264 (among other formats) from ip cameras. It doesn't require any toolboxes and should work with any recent (>2009a) version of MATLAB.You can get it through File Exchange or Github You can try the ipcam function in 15a. This may work with the MJPEG ARdrone stream.Among the things we improved between the Bebop and the Bebop 2 is the video streaming: the video feedback that is sent through Wifi to the pilot on his smartphone/tablet or on the SkyController with HDMI glasses. We call this improved streaming “stream v2”. The stream v2 has been backported to the Bebop 1 since firmware version 3.2.0. Stream v2 is based on an H.264 video encoding streamed over the RTP protocol. This means we are now compatible with common players supporting RTP such as VLC or mplayer. There is no session control protocol such as RTSP to initialize the video streaming, an ARSDK command must be used to start the streaming.

This article explains how to play a video stream from a Bebop with a third-party player (VLC for example) on a Linux PC. Please note that you cannot use the DeviceController to do this, as it consumes the incoming RTP packets. The program must simply open and maintain a connection to the drone and issue the “enable video streaming” command. It’s VLC who will consume the incoming RTP packets.parrot ar drone sdk for microsoft In order to start a stream, it is necessary to connect to the Bebop and issue an “enable video streaming” command. parrot ar drone load capacityWe can do this using a small program using the ARSDK. black ops 2 quadrotor drone review

The BebopDroneStartStream program provided within this application note does this. To use the BebopDroneReceiveStream Unix program you must have the 3.9.0 SDK compiled for the arsdk-native target. To do that, get the SDK: /Parrot-Developers/arsdk_manifests.git -b refs/tags/ARSDK3_version_3_9_0 -m release.xml ./build.sh -p arsdk-native -t build-sdk -j If you encounter any problem, please read the install documentation.parrot ar drone v1 vs v2 The source code of the program can be downloaded from the release hosted on Github.ar drone 2 prezzo Unzip this file in the folder of your choice.parrot ar drone samsung galaxy s3 Create an environement variable named ARSDK_ROOT that points to the root of your arsdk (the folder where you did the repo init command).

And finally, compile the program: Firstly your PC must be connected to the Bebop Wifi access point and have a valid 192.168.42.x IP address. Launch the BebopDroneStartStream program. It connects to the drone and sends the “enable video streaming” command. Then it just waits for a CTRL+C key press to exit. Meanwhile the drone is streaming the video to your PC. The streaming stops when the BebopDroneStartStream program is ended. In the application note files, there is an .sdp file with the following content: m=video 55004 RTP/AVP 96 As there is no session control protocol such as RTSP on the Bebop, this SDP file describes the video streaming for the player to know where to find the media and what its type is. In this file 192.168.42.1 is the drone IP address and 55004 is the client-side RTP port. If you want to change the client port value, you must also change it in the BebopDroneStartStream program. RTP ports are exchanged between the drone and the controller in the discovery connection phase.
