gstreamer.

much thanks

Hi,

Is gst using the PCR timestamp embedded in TS packets when a gst server is streaming out TS over RTP ?

If not, how gst is pacing the RTP packets at the correct rate ?

Actually, "TS over RTP" bitrate shall be compliant with the original TS bit rate to prevent buffer overflow/underflow.

Thanks in advance,

Vince.

You should write a decoder element to decode your format then -
replacing the source element is a bad design. It means you won't be
able to read your format from elsewhere - this is a pretty basic part
of designing gstreamer plugins.

You can take a look on Source/gst-plugins-base/tests/examples/app/appsrc-ra.c example which illustrates how to use custom source (appsrc) with playibin.
In addition you may consider using decodebin2  - something along this line: your_filesrc location=%1 ! decodebin2 ! xvimagesink 

Andrey.

Check the properties of playbin by "gst-inspect playbin".It will tell you
all the parameters that you can mention such as file location, source etc.

In this particular case, you should explain why you want to replace
filesrc, and add the features you need to filesrc - or (more likely)
we can suggest a better way to accomplish your goals.

To more directly answer your question, playbin2 (you should be using
this instead of playbin) will select the highest-ranked element that
can handle the uri it's given, so you'd give your new element a higher
rank than filesrc.

I don't know of any place better than this to learn gstreamer, well
the code is better but I mean written in plain English.
You can also use the IRC channel and the many implementations of
gstreamer for different platforms.

Daniel.

Hi Stefan.
U might have already got this site but this is the only place where you will
find everything related to gstreamer.
*http://gstreamer.freedesktop.org/documentation/*<http://gstreamer.freedesktop.org/>

Browse through the site completely.....Are you a plugin writer or a gstream
application wirter?
both are available on this site in name of Application Development Manual
and Plugin Writer's Guide.

As far as video knowledge is concerned I feel you google about "compression
techniques of video".
You will definitely get very useful links related to video processing and
also find the same in wikipedia.

If you get anything useful or some good ebook, kindly share the link with
this mailing list.

thanks
mayank

There are no gstreamer books. There is the online material
http://gstreamer.freedesktop.org/documentation/
and the sources.

which one do you start first. Have you tried the other way around. Also use the
debug log to see whats wrong:

GST_DEBUG="*:2" gst-launch ...

that would print warnings, if there are none go higher "*:3" ...

mfw_v4lsink is not provided by the gstreamer community. Please talk to the
people you got that element from. That
g_object_set (element, "property-name", value, NULL);
is a code snippet that you can use from your application on a element to change
a setting.

playbin takes the highes ranked videosink that is available and working.
Apparently that is fbvideosink in your case. Run something simple as gst-launch
videsttestsrc ! xvimagesink if you have a running x server with xvideo extension
(check with xvinfo command).

Well, it seems to me you are only using and Angstrom demo image, you
are not actually building the system. My first recommendation would be
to actually build your own system; then you would have all the X11
development files and what not.

However, that's not a topic for gst-embedded. I would recommend you to
the beagleboard mailing list, or the IRC channel, both are riddled
with people that have gone through the same issues before.

Hi Felipe,
	Nice to hear you back.  I am using angstrom demo image for beagle board and I downloaded it from following link.

http://www.angstrom-distribution.org/demo/beagleboard/

	This demo image contains X11 and all dependent libraries. When I use it I can get all Angstrom logo on my DVi o/p and I can run basic gstreamer tests to play video file by using ffmpeg Plugins. After that I have developed my own Plugins and implemented seeking for video Plugins. Same has been tested  well on gst-player on X86 linux system and I can easily build gst-player on fedora machine. 

	When I compile my gstreamer Plugins with help of scratchbox, there is no problem, because it gets all gstreamer libraries. But I am stuck while compiling gst-player.

	Please show me direction how can I build gst-player for beagle board?

Thanks In Advance,
Tejas.

Do you already have X11 running on your system? If so, which
distribution did you use? It might be easier to use the build system
your distribution is using.

Hi,

gst-dsp is GStreamer plug-in to utilize Texas Intruments' DSP
algorithms for OMAP3 platforms (using dsp-bridge). It's used in the
official Nokia N900 system, but should work on any platform (has been
tested on beagleboard).

It's time for the next release. There have been a huge amount of
changes, mostly for stabilization, but also some new features:

 * dynamic bitrate for venc
 * support to force keyfrane on venc
 * WMV support
 * Improved H.264 decoder support
 * New H.264 video encoder
 * Improved venc latency

In general it seems almost ready for the 1.0 release... once the WMV3
issues have been solved, and the parsers are finalized.

Thanks to all the people that contributed to this release. Here's the shortlog:

write an application that uses GstXOverlay interface from the videosink
to run in fullscreen.

hello,
           I want to learn about gstreamer and basic video. I want to know
how this video is processed and how it is displayed in display. So can
anyone suggest me a very good ebook. i googled for that but i didnt get it.
so please suggest me.
             Thank you

Hello All,

              I have downloaded gst-player-0.0.0.tar.gz source file from
following link and installed it on 0x86 system. But  now I would like to
compile the same source code with help of scratchbox and run it on beagle
board. I have tried a lot to compile all dependencies. Now I stuck up at X11
libraries.  My question is if I use gtk-target as directfb instead of X11,
will there be any problem while compiling gst-player ?

http://code.google.com/p/gst-player/downloads/list

               Please guide me to go further ahead. I am also not able to
open www.directfb.org . Please guide me to make a simple media player which
I can run on beagle board.  Is there any GUI based media player available
for beagle board which uses GStreamer as framework?

-Tejas.

Hello. I am trying to compile xorg-server for arm board. By that time i got
a erro as
*[code]checking for GL... configure: error: Package requirements (glproto >=
1.4.9 gl >= 7.1.0) were not met:

No package 'gl' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
[/code]*

So i googled then i found that gl and mesa is same. sp i compiled mesa. by
that time i got an error as
*[code]
tex-a8 -mfloat-abi=softfp -mfpu=vfp3 -ftree-vectorize -funroll-all-loops

../../../../../include/GL/glx.h:38: fatal error: X11/Xlib.h: No such file or
directory
compilation terminated.
make[5]: *** [glx_api.o] Error 1
[/code]*
Now can anyone help me how to fix this problem

Actually all these are taken as libraries. Then how can i change this
"g_object_set()" please help me. where it will?whether i have to eidt in
gstreamer source and again i have to compile to create the appropriate
libraries?Please help me
