Im trying to stream video from a Raspberry Pi (on Raspbian) to a Windows 7 PC like in this video: https://www.youtube.com/watch?v=lNvYanDLHZA I have a Logitech C270 connected to the Raspberry Pi, and have managed to stream webcam video over TCP using: gst-launch v4l2src device=/dev/video0 ! \ 'video/x-raw-yuv,width=640,height=480' ! \ x264enc pass=qual quantizer=20 tune=zerolatency ! \ rtph264pay ! tcpsink host=$pi_ip port=5000 from my Pi. Receive this using VLC works, but with a 3 sec delay. I want to do this over UDP to get a shorter delay (correct me if I'm wrong). But cannot for the life

(make make install) . I don't want to install cygwin or other windowsunix environments. Is there a GPL binary distribution of GStreamer available somewhere? (or a script that can just install it using python setup.py install) thanks UPDATE: I am using Python 2.6 (or higher). The current packages are only available for Python 2.4 or 2.5 回答1: I will answer my own question. Found this link GStreamer WinBuilds that has

After doing some googling I found Prajnashi's gst-ffmpeg plugin for Android https://github.com/prajnashi/gst-ffmpeg but it is certainly not suitable for the SDK. If the SDK does not have the required plugin how do I go about resolving this? I am new to GStreamer and have no idea how to compile any of the existing plugins for Android. 回答1: You just need to

As I looked through the source code, modules/highgui/src/cap_gstreamer.cpp seems to be the file I'm looking for. I compiled OpenCV with Gstreamer flag. GStreamer: -- base: YES (ver 1.2.3) -- video: YES (ver 1.2.3) -- app: YES (ver 1.2.3) -- riff: YES (ver 1.2.3) -- pbutils: YES (ver 1.2.3) but I'm not able to call a Gstreamer-related functions (e.g. cvCreateCapture_GStreamer which is defined inside cap_gstreamer.cpp ) cap_gstreamer.cpp was built successfully

I installed the sdk from here http://docs.gstreamer.com/display/GstSDK/Installing+on+Windows which allows me to import pygst , but it only allows me to use gstreamer 0.1 (If I try pygst.require('1.0') I get a pygst.RequiredVersionError only version '0.10' is available). I looked all over for a gstreamer 1.0 version of the sdk with no luck, so I'm hoping I can maybe alter the 0.1 sdk for my needs. I've downloaded gstreamer 1.0 from here http://gstreamer

I have an IP camera which is streaming video in MJPEG format. Now my aim is to receive it and display it in my own custom android app. For this I have three programming alternatives on android platform : Using inbuilt Anrdroid MediaPlayer class Using FFMPEG library in native C and accessing it through JNI Using GStreamer port on android to receive the stream So please suggest a better solution? I have no experience with FFMPEG or GStreamer. So what is the feasibility of doing this? Use gstreamer for it. I have used gstreamer at beagleboard which has 1GHz processor for taking image from 2
