问题 EDIT: I forgot to mention this is working with an axis encoder. I've recently started using gStreamer-sharp and I can get a video playing with playbin but I need my video to be live, thus a need to set the latency. but I have come across this error: GST_ELEMENT_PADS gstelement.c:722:gst_element_add_pad:<Source> adding pad 'recv_rtp_src_0_219678342_96' 0:00:11.033000000 13088 05418DA0 INFO basesrc gstbasesrc.c:2519:gst_base_src_loop:<udpsrc1> pausing after gst_pad_push() = not-linked 0:00:11

gstreamer: how to shift the time of rendering of one stream taken from file

由 ℡╲_俬逩灬. 提交于 2019-12-06 11:31:29
I have two media files (say, "file0" and "file1") and I want to merge them into a single one with "picture-in-picture" effect - the content from "file0" to be displayed on the whole window, and the content from "file1" will be shown on the top-left corner in the smaller box. One more point is that the content from "file1" should be rendered some time later from the base time, at the point marked as "X1" on the diagram below. In other words, if I take "videotestsrc" as a video source input, I would get the following sample pipeline which illustrates what I need to get as a result of this task:

Installing gstreamer 1.0 on windows for python 2.7.

由 余生颓废 提交于 2019-12-06 08:33:26
问题 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

place external live video frames from non supported V4L file into Gstreamer Qt , C++ Qthreads

由 半世苍凉 提交于 2019-12-06 08:04:18
OS : Ubuntu 14.04 SDK : Qt GStreamer : > 1.0 I am wondering how would I put continuously captured frames from a non supported V4L camera into GStreamer. Actually my task is to grab frames from the camera and use only GStreamer to send them to different computer via UDP. But at the moment, I just want to display it on my machine. What I did so far: a) Implemented code in Qt for an IDS camera that captures frames and displays then on Qt as live streaming. b) Separately, I have written ( or rather copied ) code that displays live streaming via gstreamer using a webcam that supports V4L file. Now

问题 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
