live audio streaming problem
Locked
 
|
I am trying to route the audio from alsasrc to alsasink. In that i am not getting the audio in alsasink. pipeline which i used is,
"gst-launch-0.10 -v alsasrc device=hw:1,1,0 ! audioconvert ! audioresample ! audio/x-raw-int, rate=44100 ! alsasink device=hw:0,0,0" where i can able to record the audio with same pipeline contruct and able to play back the recorded file. "gst-launch-0.10 -v alsasrc device=hw:1,1,0 ! audioconvert ! audioresample ! audio/x-raw-int, rate=44100 ! filesink location=record.wav" sampling frequency of the device is, alsasrc - 8KHz alsasink - 44.1KHz Can anybody guide me to procedd further? |

I used Sensoray Model 811/911/614NC/314NC (capturing raw and compressing with MJPEG) to stream over IP using GStreamer. It worked pretty good, and the commands are: Streaming Server: (IP=10.140.1.35) $ gst-launch-0.10 v4l2src device=/dev/video0 ! videorate ! capsfilter name=vfps caps=\"video/x-raw-yuv,framerate=30/1\" ! ffmpegcolorspace ! jpegenc ! multipartmux ! tcpserversink-sinkhost=127.0.0.1 port=5000 Streaming Client: (IP=10.140.5.23) $ gst-launch-0.10 tcpclientsrc host=127.0.0.1 port=5000 !multipartdemux ! jpegdec ! autovideosink $ gst-launch-0.10 tcpclientsrc host=10.140.1.35 port=5000 !multipartdemux ! jpegdec ! autovideosink or $ vlc tcp://127.0.0.1:5000 (local) $ vlc tcp://10.140.1.35:5000 (overIP) Charlie X.

The original error as reported was with XvImageSink. It probably means that the Xv option isn't supported on his system for some reason. Try using ... ! XImageSink
http://en.wikipedia.org/wiki/X_video_extension explains what this is. On Fri, Jul 20, 2012 at 6:33 PM, Charlie X. Liu <[hidden email]> wrote:

XImageSink Just a note -- at least in the past (when last I worked with this), video card drivers/manufacturers put a hard limit on the number of simultaneous xvideo output windows. In my case, I needed to display 8+ simultaneous videos and it was configurable and so xvideo was not a good option for me. glimagesink allowed me to get past the hard limit and provided reasonable performance. ximagesink (in the past) had poor performance and some odd behavior (e.g., resizing the video window mid-playback didn't update until the next frame was rendered. So with a slow framerate video, it would behave funny). If xvideo isn't working for you, you might look at seeing if there's a manufacturer-provided driver with xvideo support. _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
