gstreamer

I'm constructing a gstreamer pipeline that receives two RTP streams from an networked source: ILBC Audio stream + corresponding RTCP stream H263 Video stream + corresponding RTCP stream Everything is put into one gstreamer pipeline so it will use the RTCP from both streams to synchronize audio/video. So far I've come up with this (using gst-launch for prototyping): gst-launch -vvv gstrtpbin name=rtpbin udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263-2000" port=40000 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtph263pdepay ! ffdec_h263 ! xvimagesink

I'm trying to use GStreamer to play MP4 video from a file. I have managed to play the file using playbin2 and from the command prompt using: gst-launch filesrc location=bbb.mp4 ! decodebin2 ! autovideosink I am expecting in the future that I will need to create more complicated pipelines and hence why I'm attempting to 'program' the pipeline. In my program I am attempting to replicate the pipeline above, however I have an issue which I suspect is related to connecting the dynamic or "sometimes" source pad of decodebin2 to the autovideo sink. I am using these elements only to keep things as

I'm running into a number of issues attempting to build the GStreamer Android tutorials. My environment is: Mac OS X 7 Android SDK version 17 Android NDK 8d I am able to build and run the NDK samples both in Eclipse and from the command line. I have downloaded http://cdn.gstreamer.com/android/arm/gstreamer-sdk-android-arm-debug-2012.11.tar.bz2 and added the GSTREAMER_SDK_ROOT_ANDROID environment variable to my .bash_profile. When I try to build android-tutorial-1 via Eclipse I get the following error: 12:12:05 **** Incremental Build of configuration Default for project Tutorial1 **** /apps

I want to install Gstreamer-1.0 on Mac OS X Mavericks. So I already install gstreamer-1.0-1.6.0-x86_64.pkg and gstreamer-1.0-devel-1.6.0-x86_64.pkg from here . After that I tried to run something like this: gst-launch-1.0 fakesrc ! fakesink But got error: -bash: gst-launch-1.0: command not found So how I can install and use Gstreamer-1.0 on Mac OS X Mavericks? Som From https://stackoverflow.com/a/30873313/1162305 Try installing them with the following commands from your terminal: brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-ffmpeg The package

I am embedding a HTML5 video tag in my site, the source being a gstreamer stream. I have a pipeline working on gst 0.10: gst-launch-0.10 -v videotestsrc ! theoraenc ! oggmux ! queue ! tcpserversink port=8080 sync-method=2 I can connect to this stream via vlc like so: vlc tcp://localhost:8080 And I can also use the URL in a HTML5 video tag and the video is displayed as expected. Now I try to adapt this for gst 1.0: gst-launch-1.0 -v videotestsrc ! theoraenc ! oggmux ! queue ! tcpserversink port=8080 sync-method=2 Again I can connect to the stream with vlc, BUT I can not use this stream in a

I'm trying to stream some images form opencv using gstreamer and I got ome issues with the pipeline. I'm new to gstreamer and opencv in general. 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 that my algorithm manipulates. I did some research
