The new Version should be able to play back sound, so I would like to use gstreamer as backend. I investigated a bit in gstreamer and found out, that I need to use version 1.x with gstreamer-sharp 0.99.x binding. No problem, downloaded gstreamer-sharp 0.99.0, opened the solution with monodevelop (on linux) or xamarin (on windows) and tried to build the dll, but that didn't work. I get the error "namespace Gst.GLib" not found. I'm developing with

Specifically, I want to read chunks of the file incrementally rather than reading the whole file into memory. Some specific questions: How can I accomplish this with Gstreamer? With pygst specifically? Is there a particular "sink" element I need to use to read data from the stream? Is there a preferred way to read data from a pygst

I compiled opencv 3.2 with gstreamer for python3 on a raspberry pi 3. I have a little bash script that I use with raspivid raspivid -fps 25 -h 720 -w 1080 -vf -n -t 0 -b 2000000 -o - | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host=192.168.1.27 port=5000 I wanted to translate this pipeline in order to use it from opencv and feed into it images

I've installed GStreamer 0.10.30 and VLC 1.1.3. My only requirement is to use MPEG4 or H.264 codecs. Right now, I can stream the GStreamer videotestsrc through this simple pipeline: gst-launch videotestsrc ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink host=127.0.0.1 port=5000 which outputs the "caps" needed by the client to receive the stream: /GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps = application/x-rtp, media=(string)video

The result is that gstreamer displays ann error like: <udpsrc0> error: Internal data flow error. <udpsrc0> error: streaming task paused, reason not-linked (-1) Other cameras that I have tested are working because they define a good payload type. FFmpeg, MPlayer and other tools play the stream, although they may display a

这几天折腾了一下Centos 6.3，基本的开发使用环境搭建都使用官方的说明文档基本没碰到什么问题，当一切妥当之后，开始跑跑自己code。本人有个习惯code的时候先打开音乐播放器，这时候忽然发现Centos 本身不带有音乐播放器，索性装一个。原来在Ubuntu上面一直使用rhythmbox，这次还用她吧。 yum install rhythmbox 本以为到此就结束了。挂载磁盘，找到Win7中到音乐文件，播放文件。TNN的解码错误，需要添加另外的解码插件。 好吧，那就安装插件，可是这个插件太TM的恶心了，要么找不到，找到了又要安装很多依赖，没办法谁让用的是开源软件呢。最终又是测试，又是google，终于搞定。如下： 1、确保rhythmbox、totme安装成功，具体totme有什用处，暂时不了解。（此处，参考别人的） [root @tian software]# rpm -qa |egrep 'rhythmbox|totem' rhythmbox-0.12.8-1.el6.i686 totem-nautilus-2.28.6-2.el6.i686 totem-pl-parser-2.28.3-1.el6.i686 totem-2.28.6-2.el6.i686 totem-mozplugin-2.28.6-2.el6.i686 2、配置yum库， http://apt.sw
