Checking capabilities of GStreamer

I'm developing an application in C#/Mono in which I need to use both
audio and video bi-directionally over a sockets connection on Linux. I
am asking if GStreamer can do the following tasks:

Audio

1. Take GSM 6.10 audio from a byte array and play it on the speaker
2. Convert a PCM byte array to GSM 6.10

Video

1. Capture video from a webcam to byte array
2. Convert captured byte array to compressed format (preferably MS
MPEG42 to integrate with existing app... could be other format)

The audio functions are by far the most important right now. If
GStreamer can do the above audio functions, what do I need to download
for openSUSE 11.2 to get the latest version?

Thanks for your advice,

Steve

For inserting/getting byte arrays of data on a gstreamer pipeline you can use appsink and appsrc:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-plugin-app.html

gstreamer has GSM suppport:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-plugins/html/gst-plugins-bad-plugins-plugin-gsm.html

but i dont know if it is 6.10.

Video

1. Capture video from a webcam to byte array
2. Convert captured byte array to compressed format (preferably MS
MPEG42 to integrate with existing app... could be other format)

for video in linux you can use:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-plugin-video4linux.html

and to extract the data as byte arrays you already know :-).

The audio functions are by far the most important right now. If
GStreamer can do the above audio functions, what do I need to download
for openSUSE 11.2 to get the latest version?

I'm not very used with openSUSE, on Ubuntu i usually install almost all gstreamer plugins that comes with my distro :-). But installing gstreamer, gstreamer-base, gstreamer-good, gstreamer-bad and gstreamer-ffmpeg (I believe that the MPEG encoding will be here) should do it for you.

Thanks for your advice,

Steve

Re: Checking capabilities of GStreamer

Thanks so much for the information. My next question will show you how new I am to Linux... I tried to install everything using zypper -install gstreamer-0_10* and it installed a lot of files. When I do rpm -qa | grep gstreamer, it lists about 28 items. However, when I run gst -inspect fakesrc it says that gst is not a program.

What have I done wrong... or what have I not done. Winking smile emoticon

D'oh... my bad. There it's gst-inspect, not gst -inspect... sorry. Out of curiosity, what's the difference in gst-inspect and gst_inspect-0.10 (or other programs with -0.10)?

i believe gst-inspect is a link to gst-inspect-0.10.

gst-foo is a wrapper binary that will check for existing gst-foo-X.Y and
then call the one with the highest version. (I have no idea what the
point of this is though, since there will likely be incompatibilities
between different major versions, so calling the unversioned gst-foo
rather than the versioned one is is likely to cause problems in future
when we start hacking on 0.11. IMHO the unversioned binaries should just
go away in future.)

And then you should try 'gst-inspect', there is no space after gst.

Re: Checking capabilities of GStreamer

In reply to this post by Tiago Katcipis

I'm writing in C# using MonoDevelop and Mono. What would be the best approach to take in order to use GStreamer from C#... keeping in mind I want to do the things listed below. Unfortunately, I'm new to Linux and gstreamer. I know there is a C# binding (gstreamer-sharp) but don't know if it will do the GSM conversion. Use the gstreamer-sharp stuff, call a c module, something else? Heck, I'd even pay someone to develop this! Winking smile emoticon

Thanks for any direction you can provide,
