you need to export PKG_CONFIG_PATH to include $prefix/lib. RUn pkg-config
--list-all | grep gstreamer and check that it lists the missing ones. Make sure
its not picking up the host ones.

You are probably expecting too much. Are you building with optimizations,
disabling some gobject runtime checks, ...)? Are you using own codecs optimized
for your platform?

[gst-embedded] Gstreamer cross compilation doubt

[Niamathullah s. <arm...@gm...>]

Hello,
   I am compiling gstreamer for my freescale arm based board. i am getting
some errors when i compile it. actually the problem might be with my side.
because i dont know how to link all the files and library files which is
needed for compilation.
i exported the cross compiler path. after that i used ".configure" command.
In that i am getting this below error
"checking for arm-linux-gnu-pkg-config... no
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GST... yes
checking for GST_BASE... yes
checking for GST_PLUGINS_BASE... no
configure: error: no GStreamer plugin base libs found
Configuration of glib library has failed"

Now i to solve this problem and how to link codecs with this compilation and
how to link codec libary files. please help me

  Kindly help me

[gst-embedded] Need some info for GUI based player which is using Gstreamer as media framework on Beagle Board.

[Tejas B. <te...@or...>]

Hello All,
             I have developed my own plugins called flvparser and flvdec. I can run flv files on 86 platform as well as on beagle board. I am running it as followed.


#gst-launch-0.10 filesrc location=1.flv ! flvparser ! flvdec ! ffmpegcolorspace ! ximagesink on pc platform and on beagle board as followed.

#gst-launch-0.10 filesrc location=1.flv ! flvparser ! flvdec ! ffmpegcolorspace ! fbdevsink 

            In both case it is working fine. I can play flv files in totem player on PC platform. 

            Is there any player available on beagle board like totem which is using gstreaemer as media framework. 

            Please correct me if i am wrong. And also clarify me.

Thanks In Advance,
Tejas.

[gst-embedded] Performance problems playing video with Phonon and GStreamer on QT Embedded.

[Marcos <ma...@co...>]

I have serious performance problems playing videos in my embedded linux
platform, an ARM AT91SAM9263 Evaluation Kit (AT91SAM9263-EK).
The video delays more than 30 seconds to start after be executed and this
consume so much system resources and skip a lot of frames.
The only one format and codification that I have been able to play is codec
with M-JPEG and AVI or MOV package, maybe that can be related.

Do you have any consideration, configuration or recommendation to improve
the performance?

Marcos Rodriguez.

[gst-embedded] configure: error: Could not link libxml2 test program

[zhonglei z. <zzl...@ya...>]

Hi all,

I want to cross compile gstreamer. 

When i run 
./configure --prefix=/usr/local/arm/deps/gstreamer --host=arm-none-linux-gnueabi --enable-shared

It reports "configure: error: Could not link libxml2 test program."

I have already set these:
GLIB_CFLAGS="-I/usr/local/arm/deps/libxml2/include"
GLIB_LIBS="-L/usr/local/arm/deps/libxml2/lib"
PKG_CONFIG="/usr/local/arm/deps/libxml2/lib/pkgconfig:/usr/local/arm/deps/glib/lib/pkgconfig"

Now i don't know what libxml2 test program refers to. Do you know how to solve it?

Thanks,
ZHU Zhonglei

[gst-embedded] media player using gstreamer in X11 windows without GTK+

[Hong F. <fen...@mr...>]

Hi,

Is it possible that the media player use gstreamer in X11 windows without GTK? I only need few functions, i.e. start, stop, pause and resume. I think it is possible. If you have any example source codes or documents, please feel free to share with us.

Thanks in advance.

Regards

Hong Feng

It sounds like mpeg4videoparse, then - better to use a well tested
existing plugin than a custom one.

However, that won't cause a crash by itself.

None of this is the cause of your crash. Your crash is simply a bug in
your plugin - and without the source to your plugin, or even any
details about where it's crashing, there's no possible way we can help
you any more than that. Good luck with your debugging!

Subject: Need Help to run my plugin


Hi All,
           I have installed gstreamer-0.10.25 and gstreamer-base-plugins-0.10.25. And i have tested following video testsrc plugins.


gst-launch-0.10 -v videotestsrc ! ffmpegcolorspace ! ximagesink and it is working fine.


            I have develop following 2 plugins and i want to get display from my video decoder. I am using following pipe line.


gst-launch-0.10 filesrc location=~/test.m4v ! yuv ! mpeg4dec ! ffmpegcolorspace ! ximagesink

            Here yuv plugin will read raw data from filesrc and push raw data to mpeg4decelement. Mpeg4dec element decode raw data and genearte yuv data and same will be pushed to ffmpegcolorspace element. When i run that pipeline it gives me following error.

Well, what does your 'yuv' plugin actualyl do? It presumably has
nothing to do with raw YUV data - it's possibly doing somethign with
an mpeg4 elementary stream? You haven't provided any specifics.

Without knowing what your plugins are even _supposed_ to do, it's hard
to give much advice.

Well, this is simple - your plugin crashed. You need to fix it to not
crash. I don't know what you want help with exactly - we can't debug
it since you haven't provided the source.

Your gst-inspect output isn't obviously _wrong_ (since you haven't
said what your 'yuv' plugin does), but it's obviously missing a lot of
details - like a description, and template caps that are more specific
(which you probably, but not certainly, want).

[gst-embedded] need some information for VC1 decoder

[Mayank K. <er....@gm...>]

hi friends

I have to write a gstreamer plugin for VC1 deocder and I need to set the
capabilites such as Mime type its min and max height and width etc.

Also how to procees in chain_functioin and how to decode it to yuv format.

I am not getting any good reference of VC1 from internet so finally decided
to contact here.

It will be great for me if i get some help on that.

thanks

[gst-embedded] Cross compiling to arm, NO PLUGINS FOUND

[Martin T. <mar...@me...>]

Hi,

I did cross compile gstreamer, base- and good-plugins for an arm(11)
target (without using "scratchbox"!). Compiling worked fine but not all
the plugins are found. "gst-inspect" shows only:

> staticelements:  bin: Generic bin
> staticelements:  pipeline: Pipeline object
>
> Total count: 1 plugin, 2 features

A former solution for this problem, using "glib_cv_uscore=no", does not
work for me. Plugin libraries are there and the "GST_PLUGIN_PATH" is set
correctly. I'm checking the web for days now, any ideas how to fix this?

Thanx in advance!

are you sure it working (e.g. properly cross compiled). just run ldd on a plugin
that uses liboil and on liboil itself.

gst-plugins-bad has xvid and then there is of course gst-ffmpeg.

export PKG_CONFIG_PATH if you install to non-standard locations. If you use
scratchbox, just build with --prefix=/usr.
