[gst-devel] how to cleanly re-install gstreamer? Help!!

[Yiliang Bao]

Hi,

I compiled and installed the latest gst-rtsp-server, and updated gstreamer
itself based on the error messages from gst-rtsp-server installation.
However, after these steps, I could no longer find some plugins like mad,
xvimagesink, v4l2src, etc. 

I have tried re-installing the latest versions of all plugin packages. I
have also tried to remove, then re-install all plugins from Synaptic Package
Manager. Got some plugin, like v4l2src, back, but mad, xvimagesink are still
missing. autovideosink is there, but some pipleine which works is no longer
working. For example:

gst-launch v4l2src device=/dev/video0 ! autovideosink

>>>>>> Error messages:

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0:

gst-launch filesrc location=Videos/xyz.avi ! decodebin ! autovideosink

Does anyone know why? Is it possible to re-install a clean version of
gstreamer?
