GStreamer中的Muxing音频和视频冻结

Question

Could anybody provide example of working pipeline for muxing video and audio? I've found one here and tried to change it for using encoders I need but it doesn't seem to work.

Here's how pipeline looks like:

gst-launch -v v4l2src always-copy=true num-buffers=200 input-src=composite ! \
"video/x-raw-yuv,format=(fourcc)NV12,width=480,height=320" ! \ 
TIVidenc1 codecName=h264enc engineName=codecServer byteStream=FALSE ! \ 
queue ! muxer. \ 
alsasrc num-buffers=200 ! "audio/x-raw-int,width=16" ! \
    TIAudenc1 codecName=aaclcenc engineName=codecServer ! queue ! muxer. \
avimux name=muxer ! filesink location=output_cap_.avi

When I'm running this pipeline it just freezes. Here's the output:

(gst-launch-0.10:1792): GStreamer-WARNING **: External plugin loader failed. This most likely means that the plugin loader helper binar
y was not found or could not be run. If you are running an uninstalled GStreamer setup, you might need to update your gst-uninstalled s
cript so that the GST_PLUGIN_SCANNER environment variable gets set.

There are a lot of hardware specific things but maybe I'm just using wrong syntax.

Answer 1

I don't know exactly what the problem is, but I wanted to point out that the avimux example you linked is for gstreamer-1.0 (and it works for me). However I see that you are using gstreamer 0.10 which is quite old now. If possible, try upgrading to the latest version and see if that helps.
