gstreamer

This is python code for capturing streaming video from server. but I need to write a function to extract one frame from the flow. It will be a button. On click it will show current frame. I have no ideas. Can anyone help me with this??? self.player = gst.Pipeline("player") self.source = gst.element_factory_make("uridecodebin", "video-source") #self.source = gst.element_factory_make("playbin2", "video-source") sink = gst.element_factory_make("xvimagesink", "video-output") colorspace = gst.element_factory_make("ffmpegcolorspace") scale = gst.element_factory_make("videoscale") self.source.set

I need to call Gstremaer inside an openCV code (opening a video camera essentially). 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 as the opencv install log suggested: [ 17%] Building

I've been trying to install gstreamer 1.0 on windows to use as a python 2.7 module. 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.freedesktop.org/data/pkg/windows/1.5.2/ but I'm not

I have written gstreamer code for camera live-streaming and recording at the same time. My pipeline looks like that: / [ queue1 | videosink ] v4l2src | tee \ [ queue2 | filesink ] Currently both live streaming and file recording is working together. Now I need to start the pipeline with only one queue i.e. queue1 (live streaming queue), After a while I need to add the recording queue and remove it dynamically too. My working code are given below : pipeline = gst_pipeline_new ("rv_camera"); /*Create source element. We use mfw_v4lsrc from Freescale as source */ source= gst_element_factory_make

I'm playing a transport stream file (*.ts) using the following pipeline: gst-launch-0.10 playbin2 uri=file:///c:/bbb.ts But I need to convert that into a pipeline myself. I'm not sure how to achieve this. So far I have tried: (works fine) gst-launch-0.10 -v filesrc location=c:/bbb.ts ! tsdemux ! audio/x-ac3 ! fakesink But if i replace fakesink with autoaudiosink it fails with a not-linked error. And even the fakesink doesn't work for video: gst-launch-0.10 -v filesrc location=c:/bbb.ts ! tsdemux ! video/x-mpeg2 ! fakesink So I have two questions: How to find out pipeline created by playbin

I want to play two different local video files at the same time in a single window. The code below without demux and decoder works fine. static void play_video(){ GMainLoop *loop; GstElement *pipeline,*videomixer; GstElement *src,*sink,*filter,*csp,*videobox; GstElement *src1,*filter1,*csp1,*videobox1; GstElement *srcb,*filterb,*cspb,*videoboxb; GstCaps *filtercaps,*filtercaps1,*filtercapsb; GstPad *pad,*pad1; const char pattern = "snow"; loop = g_main_loop_new(NULL, FALSE); pipeline = gst_pipeline_new("my-pipeline"); src = gst_element_factory_make ("videotestsrc","src"); src1 = gst_element

I am trying to query a list of available video capture devices (webcams) on windows using gstreamer 1.0 in c++. I am using ksvideosrc as source and i am able to capture the video input but i can't query a list of available devices (and their caps). On gstreamer 0.10 it has been possible through GstPropertyProbe which is removed in gstreamer 1.0. The documentation suggests using GstDeviceMonitor. But i have no luck using that either. Has anyone succeeded in acquiring a list of device names? Or can you suggests another way of retrieving the available device names and their caps? Although I haven

I tried using phonon to play the video but could not succeed. Off-late came to know through the Qt forums that even the latest version of Qt does not support phonon. That's when I started using Gstreamer. Any suggestions as to how to connect the Gstreamer window with the Qt widget? My aim is to play a video using Gstreamer on the Qt widget. So how do I link the Gstreamer window and the Qt widget? I am successful in getting the Id of the widget through winid() . Further with the help of Gregory Pakosz, I have added the below 2 lines of code in my application - QApplication::syncX(); gst_x
