Gstreamer is not working (Windows)

I've tried to locate the cache but it doesn't exist.

This is the locations I tried on my system but the INetCache didn't exist even with hidden files showing
%USERPROFILE%\AppData\Local\Microsoft\Windows\INetCache\gstreamer-1.0\registry.x86_64.bin

I tried manually searching but no luck and even windows search box.

Assuming this is in regard to RTPBin, there is an action signal called "get-
session" with the following signature:

   The ?get-session? signal

   GstElement*
   user_function (GstRtpBin *rtpbin,
                  guint      id,
                  gpointer   user_data)

The id being the name number as found on the pad you have requested (usually 0,
1, ...).

   g_signal_emit_by_name (rtpbin, "get-sesssion", id, &rtpsession);

Try to insert h264parse after nvh264enc, which can add PPS in the stream
gst-launch-1.0 videotestsrc is-live=true ! nvh264enc ! h264parse
config-interval=1 ! mpegtsmux ! hlssink playlist-length=100
target-duration=5 playlist-location=nvh264enc.m3u8 location=nvh264enc%u.ts

What I meant by two pipelines is to use an appsink in the capture pipeline. And
then have you application pass the buffers to the "recording" pipeline through
an appsrc element. Optionally, intervideosink/src might do the job for you.

Nicolas

As a followup on what Nirbheek said, this might be helpful:
http://gstreamer-devel.966125.n4.nabble.com/msvc-build-can-t-find-elements-in-playback-plugin-td4691649.html#a4691668

Basically you need to clear the plugin cache whenever you go between mingw
and msvc builds.
