Hi Sean,

Thanks a lot for the detailed explanation.

I tried both options. Here is what I encountered. Some of information might
be helpful for other people who gets into the same trouble.

What I did -->

Originally I installed all the packages using "apt-get ****" from command
line. So they should be official releases. I upgraded gstreamer by compiling
the latest source, it worked fine after resolving some library issues. After
I ran ./configure for the latest base plugin package before I ran make and
install, I found that all the old plugins (almost) were gone. I was able to
resolve most dependencies by installing the development libraries
(libXXX-dev) except for 4 plugins related to header files. After I installed
the base set, I moved on to the good set, and found more problems. I
patiently tried to solve all the library related dependency issues, but was
left with more plugins that could not be built because of header file
related issues.

After I finished upgrading base and good set. I tried to construct some
pipelines with plugins already installed after my best efforts mentioned
above, but no luck. These pipelines that were working previously no longer

1. Reinstall the old packages from package manager

After I messed up with gstreamer, I tried to install the old packages using
"apt-get" command, but it said all the packages are the latest, even though
I knew most plugins were already removed.

So this option seems to have some problem.

2. Continue compiling from source

After wasting quite some time, I decided to move ahead with other packages
by ignoring these plugins that I had no idea how to resolve the issues.
Resolving library related dependency issues was rather tedious, but it is
fairly straightforward. I just tried to find the development libraries in
package manager with name similar to that complained in the ./configure

Finally, I was able to able to install all the packages. Although many
plugins were left un-installed, gstreamer works fine for the functions I
tested, and RTSP server is also working now.

Thanks again for all the replies!
