I have a c++ program using gstreamer. The problem is that several of my elements–namely the ffmpeg plugins–do not work in the program. However when I run for example:
gst-inspect | grep ffenc_h261 It shows up.
If I run gst-launch .... ! ffenc_h261 ! ... , it works.
However in my application, I always receive element ‘ffenc_h261’ not found or something like that.
Any ideas?
Turns out that my distro was all flubbed up. I uninstalled everything that uses gstreamer, sudo apt-get purge gstreamer*, then downloaded all of the source, compiled, and installed. It was a real pain in the ass, but I got it working. One more reason that most package managers are nice, but are no substitute for knowing how to use a compiler and make.
The most annoying thing about both yum and apt is that when they are installing something like gst-ffmpeg-plugins, the package manager does not tell you that it is disabling certain features bacause another feature isn’t installed.
Maybe I should complain about that to debian. Anyways, reading the output of ./configure is the way to go.
