gstreamer

I have problem with recording streams using gstreamer. I have to write audio and video separately and cut in when signal arrived. I have correctly working video, but still have problems with wav files. Even simple pipeline in gst-launch don't work correctly. I have wave file and I am trying to split it using multifilesink: gst-launch filesrc location=test.wav ! multifilesink location=test2%d.wav next-file=4 max-file-size=512000 But final wav files are corrupted while the same pipeline with ts files is working ok: gst-launch-1.0 filesrc location=test.ts ! multifilesink location=test2%d.ts next

I try to make a H264 RTP stream from a Raspberry Pi 3 with a camera module to a video tag. Using the following code to start the stream raspivid -t 0 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o - | \ gst-launch-1.0 -v fdsrc \ ! h264parse \ ! rtph264pay \ ! gdppay \ ! udpsink host="192.168.0.11" port=5000 Then I provide a simple webpage with a video tag: <video id="videoTag" src="h264.sdp" autoplay> <p class="warning">Your browser does not support the video tag.</p> </video> The src references the following SDP file: v=0 m=video 5000 RTP/AVP 96 c=IN IP4 192.168.0.51 a=rtpmap:96 H264/90000 When I

HI I am trying to record rtsp stream coming from camera(H264 format). I am using following gst command to do recording in MPEG4 Format gst-launch -e rtspsrc location=rtsp://10.17.8.136/mediainput/h264 latency=100 ! decodebin ! ffenc_mpeg4 ! avimux ! filesink location=test.mp4 and H264 format gst-launch-0.10 -e rtspsrc location="rtsp://10.17.8.136/mediainput/h264" latency=100 ! rtph264depay byte-stream=false ! capsfilter caps="video/x-h264,width=1920,height=1080,framerate=(fraction)25/1" ! mp4mux ! filesink location=testh264.mp4 Both are doing recording but i have observed that There is RAM

2012-5-29 最新版本的fedora17正式版发布了，所有下载方式： http://fedoraproject.org/zh_CN/get-fedora-all 此篇文章由之前"Fedora16安装后配置"改动过来的，再配上个人的使用经历，供fedora爱好者共同参考学习， 其实安装后的配置都差不多的。 1.设置sudo (个人使用习惯, 用 su -c '命令', 也可，跳过) 使用visudo命令或 vi /etc/sudoers ## Allow root to run any commands anywhere root ALL=(ALL) ALL 添加下面内容，goface替换成你的用户名 ‘goface’ ALL=(ALL) ALL 2.更新系统和软件 #yum check-update #yum update 新安装成功后的系统，首先update一下，新安装系统马上有更新的，说明更新的内容修正了系统合成后软件出现的问题， 个人认为很重要的更新，我的电脑安装完好，发现背景亮度无法调节，更新完好修正。 3.安装系统高级配置工具 # yum install gnome-tweak-tool gnome-tweak-tool 当然要装喽 fedora gnome3默认桌面是不能点击的，可使用gnome-tweak-tool解放桌面，添加上“Computer” 等图标

1.Ubuntu上安装gstreamer库： apt-get install libgstreamer0.10-0 apt-get install libgstreamer0.10-dev apt-get install libgstreamer0.10-0-dbg 2.编写测试gstreamer库的helloworld.c: [html] view plain copy #include < stdio.h > #include < gst /gst.h > int main (int argc,char *argv[]) { const gchar *nano_str; guint major, minor, micro, nano; gst_init (&argc, &argv); gst_version (&major, &minor, µ, &nano); if ( nano == 1) nano_str = "(CVS)" ; else if ( nano == 2) nano_str = "(Prerelease)" ; else nano_str = "" ; printf ("This program is linked against GStreamer %d.%d.%d %s\n", major, minor, micro, nano_str); return
