gstreamer

Am using Ubuntu(14.04) and I am getting this error while trying to use gstreamer. gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! x264enc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5000 I have checked the gst-inspect-1.0 v4l2src It say element not found "No such element or plugin 'v4l2src'" What should I do ? From where can I get this element or plugin. I have tried resinstalling entire gstreamer. But am unable to do so. the v4l2src plugin belongs to the gstreamer-plugins-good package; so sudo apt-get install gstreamer1.0-plugins-good should help you out Gstreamer

I'm trying to cross-compile GStreamer. Version is 1.2.3. Host PC's OS is x86 linux and Target system's OS is MIPSEL linux OS. I succeeded to compile gstreamer and plugins for target device. And gst-launch-1.0 could be executed. So I tried to use basic plugin, libgstvideotestsrc. But it didn't work. So I ran ```gst-inspect-1.0' to inspect plugins then I found the result like below. # gst-inspect-1.0 -b Blacklisted files: libgstinterlace.so libgstfbdevsink.so libgstgeometrictransform.so libgstmultifile.so libgstencodebin.so libgstfestival.so libgstlevel.so libgstdvdspu.so libgstauparse.so

Can I somehow tell GStreamer to look for plugins in a specified directory? Use the GST_PLUGIN_PATH environment variable to point at the directory you want, or programatically just call: GstRegistry *registry; registry = gst_registry_get_default(); gst_registry_add_path(registry, directory); KDawg You can no longer do this programmatically in gstreamer 1.0. In the above answer, gst_registry_get_default() was replaced with gst_registry_get() and gst_registry_add_path() was removed. You can also set GST_PLUGIN_SYSTEM_PATH to the location of the Plugins. Not sure what the difference is between

So I am starting a project that is going to make use of the gstreamer libraries. I am running the test project from the gstreamer documentation and am getting the following error.This program worked properly on archlinux but is erroring out on ubuntu gcc `pkg-config --cflags --libs gstreamer-0.10` main.c -o player /tmp/cciFhGCe.o: In function `main': main.c:(.text+0x1e): undefined reference to `gst_init' main.c:(.text+0x36): undefined reference to `gst_version' collect2: ld returned 1 exit status make: *** [player] Error 1 My code is the following which I got from the gstreamer documentation

I have a project that runs Python 2.7, PyGTK 2.24, and the most recent version of PyGST. I am getting a weird intermittent error in the following code. With the first, longer error, the video will play just fine, and the error will only appear AFTER I close the video window. The second prevents the window from opening at all. import pygtk pygtk.require('2.0') import gtk, pango import pygst pygst.require('0.10') import gst import Trailcrest import os, sys class Video: def __init__(self): def on_message(bus, message): if message.type == gst.MESSAGE_EOS: # End of Stream player.set_state(gst.STATE
