gstreamer

In my code when I open the 2nd vlc 1st one starts from the beginning with 2nd one. But it must be like that: While the first client is still running, the second/third/etc client should start at approximately the same position as the first client currently has. What should I add to my code for that problem. I am working with Windows VisualStudio. #include "pch.h" #include <iostream> #include <gst/gst.h> #include <gst/rtsp-server/rtsp-media.h> #include <gst/rtsp-server/rtsp-server.h> #include <gst/rtsp-server/rtsp-media-factory-uri.h> #define PORT "8554" static char *port = (char *)PORT; static

Gstreamer整体框架 Gstreamer是一个用于开发流式多媒体应用的开源框架，采用了基于插件（plugin）和管道（pipeline）的体系结构，框架中的所有的功能模块都被实现成可以插拔的组件（component）， 并且能够很方便地安装到任意一个管道上。由于所有插件都通过管道机制进行统一的数据交换，因此很容易利用已有的各种插件“组装”出一个功能完善的多媒体应用程序。 Nvidia为Gstreamer开发了许多plugin，这些plugin能够利用Nvidia硬件进行加速。Nvidia的deepstream就是基于gstreamer开发的。 下图是对基于Gstreamer框架的应用的简单分层： 1.1 Media Applications

I am writing gstreamer application and need to transfer output audio/video stream over rtsp. But in gst-rtsp-server examples I have founded factory creation only by gst-launch syntax: factory = gst_rtsp_media_factory_new (); gst_rtsp_media_factory_set_launch (factory, "( appsrc name=mysrc ! videoconvert ! x264enc ! rtph264pay name=pay0 pt=96 )"); Is it possible to connect gst-rtsp-server elements to my pipe? You have to subclass rtsp-media-factory and override default_create_element that will return your pipeline as GstElement 来源： https://stackoverflow.com/questions/22993373/how-to-use-gst

I am trying to stream cast a computer generated video using gstreamer and icecast, but I cannot get gstreamer appsrc to work. My app works as expected if I use xvimagesink as the sink(see commented code below). But once I pipe it to theoraenc it does not run. I exchanged shout2send with filesink to check if the problem was icecast, the result is that no data is written to the file. Substituting appsrc with testvideosrc works as expected. Any suggestion? #!/usr/bin/env python import sys, os, pygtk, gtk, gobject import pygst pygst.require("0.10") import gst import numpy as np class GTK_Main: def

I have created a network stream with following gstreamer commands: sender: gst-launch-1.0 -v videotestsrc ! video/x-raw,framerate=20/1 ! videoscale ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! udpsink host=X.X.X.X port=5000 receiver: gst-launch-1.0 -v udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! autovideosink This just works fine. I now want to include the stream on the receiver side in a python script. In the script

does anyone know how i would go about using a tkinter window as an output from a videosink/pipeline from within python? i have found methods for lots of other GUI systems, but i dont want to have to use tkinter and something else together xxx thanks in advance x This works for me on Windows 32-bit. I get a seg fault on Linux or Windows 64-bit. Sorry, I don't know about Mac. You have to use bus.connect("sync-message::element", on_sync_message) and pass a Tk widget ID ( winfo_id ), as you can see in the following code. The container can be any Tk widget, but a solid black frame seems to work
