[H264] : no encoder detected despite successful gst-libav installation

If you can find the libgstlibav.dll file, run gst-inspect on it. Like:

gst-inspect \path\to\libgstlibav.dll

This inspects the specified plugin directly, without going through the 
registry. If this produces errors, then you know something weird is 
going on. Same if you don't see h264 elements listed.
