newbie gstreamer sdk problem

I just got the gstreamer SDK for Windows from
http://docs.gstreamer.com/display/GstSDK/Installing+on+Windows and the
tutorials seem to compile and run which is a good start. :)

Then as suggested in the first tutorial I edited the source code to
specify a local file and it doesn't work :(

I tested the link by Ctrl clicking it in the source code in visual
studio and windows media player then opens and plays my media no
problem. I tried an .avi file as well as .mp4 file and neither of them
will render on gstreamer :(

IOW in basic-tutorial-1.c I replaced the line:

pipeline = gst_parse_launch ("playbin2
uri=http://docs.gstreamer.com/media/sintel_trailer-480p.webm", NULL);

with:

pipeline = gst_parse_launch ("playbin2
uri=file://D:/AudioDriver/sample.avi", NULL);

what could be going wrong?
Thanks for any help :)

Try
uri=file:///D:/AudioDriver/sample.avi
instead of
uri=file://D:/AudioDriver/sample.avi

Each time I want to open a new file I use this code in C#:
playBin.Uri = @"file:///" + fileName.Replace('\\', '/');

Re: newbie gstreamer sdk problem

Thanks for that info Ralph. I added another / as suggested
interestingly now the .avi file plays the sound but sadly still not
the video.
My .mp4 file still doesn't play at all through gstreamer but is fine
in Windows media player.

I suddenly wonder if this is because I built a 32 bit application but
am running it on a 64 bit OS... I kind of assumed that 64 bit Windows
can always run 32 bit apps but maybe that is not so with gstreamer?
I'll install the 64 bit version and give it a try now.

Hi,

You are missing a slash, it should be file:// + /d:/path/to/file. It's
a bit weird but even if it's a windows-style path, it should start
with a slash. We will update the docs to make this clear.

Very good idea. I remember that it took me a few hours to figure it out first time.

I'm writing WPF C# applications and in order to make them work with GStreamer I must build them in x86 mode (32-bit). 64-bit Windows is capable of running all 32-bit applications, so if you can't see the video, the problem must be somewhere else. Try playing different video files (using a diffrent codec).

That shouldn't be a problem at all. You are probably missing some
plugins in your installation.
When you installed the SDK, did you check all options or did you just
used the default install?
I am asking because for H264 decoding, you will need to have the
ffmpeg plugin installed, which are not installed by default.
If that's the case, running GST_DEBUG=3 gst-launch-0.10 playbin2
uri=file:// will show you what's missing.

Re: newbie gstreamer sdk problem

Thank you Andoni, that solved the problem completely! I had indeed
only done the default installation and didn't realize that would not
include codecs for some common formats.
Also thank you for explaining about setting the GST_DEBUG environment
variable it will be very useful :^)
