Hi,
I am trying to add Pango font rendering ability to Leopardboard, which can be very useful in adding subtitles and text rendering to the video output.
Example on a Linux Machine
I have explained the whole idea here: Text or Bitmap Overlay
Thanks to Todd, I am somehow familiar with the structure of the build process in RRSDK.
I have added a new folder under $DEVDIR/fs/apps called /pango-1.29.4/ and I have also added Config, Makefile, metainfo files to the folder and I have set the desired settings.
I have also enabled Cairo, Fontconfig in make config
When I try to make the package, I get this error:
/opt/codesourcery/arm-2009q1/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/../../../../arm-none-linux-gnueabi/bin/ld: skipping incompatible /usr/lib/libX11.so when searching for -lX11

make[2]: *** [all-recursive] Error 1
make[1]: *** [all] Error 2

It seems it is trying to integrate X11 related stuff to the package which is not available on the target machine.
Can anyone help me about it?
Thanks
Morteza
I successfully compiled Pango, and there is no error.
I figured out that it is trying to add X11 support and I checked the /src/configure script. There is an undocumented switch which I added to my Makefile (ac_cv_have_x=no)
Here is my Makefile:

When I try the make command at $DEVDIR/ I get this error:

Thanks Everyone!! :)
I solved it myself.
I looked into $DEVDIR/fs/fdsev/ for the compiled libraries (libpango-1.0.so) and found out that the path I was using inside the Makefile was incorrect.
I fixed it and it works like a charm now.
In the near future I will post a tutorial on the format of Makefile (as the info from RidgeRun does not cover the basics)
Here is the steps I took to integrate Pango into my build:
1- Create a new folder under $DEVDIR/fs/apps and rename it to pango-1.29
2- Create two text files inside $DEVDIR/fs/apps/pango-1.29 and name them Config and Makefile and use the codes below for them.
Makefile: (v0.2 Added Binary files and fixed LA path)
Config: (v0.2 FontConfig and DejavuFonts are added as dependencies for PANGO)
3- Then you must clean the GST-Base plugins to force it to be made again so Pango is integrated into it this time.
cd $DEVDIR
`make env` (Please note that the special characters ` are not single quote ' characters, they are the same key which produces ~ but without the shift key!)
cd fs/apps/gst-plugins-base-0.10.32
make clean
make
make install
It must compile and integrate without any error.
If you run gst-inspect on your LeopardBoard now you will see that there are 4 new elements:
Thanks for all the attention :)
Here are some tests with Pango and the pipelines which produce them on Leopardboard
Text Overlay:
gst-launch videotestsrc ! textoverlay text="Morteza" font-desc="Verdana bold 80px" ! autovideosink
Time Overlay:
gst-launch videotestsrc ! clockoverlay shaded-background=1 font-desc="Arial 60px" ! autovideosink
Hi Morteza,
Look at how simple and clean your integration Makefile and your Config files are once you get the details right. You did a great job.
Documentation for creating the Makefile and Config files can be found at
www.ridgerun.com/.../RidgeRun_2011Q2_SDK_Development_and_Integration_Guide
and by running
$DEVDIRmake docfirefox $DEVDIR/documentation/html/index.html
and looking in the autotools class module.
Please add some pipelines using v4l2src and add dmaiperf so we can see the frame rate. How does using the overlay element effect the framerate?
Todd
Thanks Todd,
As you asked, I ran some tests on V4L2SRC and here are the performance outputs from my LeopardBoard 365 @ 297Mhz
Pipeline without overlay:
gst-launch -e v4l2src always-copy=FALSE input-src=composite ! 'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480,pitch=736'! dmaiperf ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite sync=false
gst-launch -e v4l2src always-copy=FALSE input-src=composite ! 'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480,pitch=736' ! textoverlay text="Morteza" font-desc="30px" !dmaiperf ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite sync=false
As you might have noticed from the last picture, font rendering with Pango is very complicated. It has Shadow and Outline. Unfortunately you can not disable them to improve performance in gst-plugins-base 0.10.xx. The support for changing Shadow and Outline is added in gst-plugins-base 0.11.xx.
I suspect that the shadow which uses alpha blending is the slowest part and should be disabled.
So I am going to give it a try and update my gstreamer to gstreamer 0.11.1 and also all the plugins (BASE, GOOD, BAD)
Will there be any problem in the process?
For anyone interested in the topic, I must add that there are two steps in a new installation of Pango before you can use it.
First you have to update the Pango plugins registry by updating your pango.modules file in /usr/etc/pango by:
The next step is updating the list of available fonts in your system by:
Please note that "Font Config" and some fonts (e.g. DejaVu Fonts) must be selected from make config > Filesystem Configuration > Select target's file system software.
If there is any questions, I would be happy to help.
Thanks a lot for the instruction. It's greatly an useful issue, if works!
I have done the steps carefully but received not a successful response!
I copied the build output. I have not seen any trace of Pango in output but highlighted warning for Cairo! I am not sure if it's important.
I activeted the necessary LIBs and created the "config" and "makefile" in the right folder as you said.
For you information, if I make a mess into "config" file deliberately, "make config" makes an error (fs/apps/pango-1.29/Config:8: unknown option "....") .. it shows the files are considered! but Leopard command line "gst-inspect" does not shows the expected libraries.
Do I miss some thing else?

Hi Morteza, hi Jack,
first thank you Morteza for your tutorial to implement pango to leopardboard.
I followed your tutorial Mortezam but
I'm sad, I got the same warning like Jack:
Checking dependencies for cairo-1.10.2
ls: cannot access DirectFB*: No such file or directory
And when I do gst-inspect on leopardboard, pango is not listed there.
Do you have any suggestions? Or Jack, did you solve the problem?
Stefan
OK, got it.
The DirectFB cairo dependencies were not the problem.
I think I had forgotten one step the last time.
Now I created the pango diretory under $DEVDIR/fs/apps and created the makefile and the config file in it.
in the pango directory i did make and this works, so i did a make clean.
I switched to the gst-base-flugin folder did a make clean, a make, and a make clean again, everything works.
I switched to $DEVDIR
make config -> selected pango an its dependencies
did gst-inspect on leopardboard and pango was found.
last but not least i did threpango-querymodules thing and fc-list and now it works.
Thanks Morteza
Hi Jack and STEFAN81,
Can you do me a favor and run the same pipelines I have tested above on your boards and report the FPS benchmark.
I want to test the performance of different boards (Dm365, DM368,...)
Thanks in advance.

Thanks a lot Stefan.
You did a great job!
The performance data you posted is very helpful.
But I think you forgot to mention the Board and the CPU clock you were running the board on.
It seems that the TextOverlay plugin is a CPU hungry plugin. I am tweaking GStreamer a little bit to remove Alphablending under the text, which I suspect is makes it slower.
When it is ready I will post the patch here too.
you're welcome.
you're right.. i use leopardboard dm368 with ridgerun evalSDK for leopardboard DM365.
i did not change the pll settings, so it's running on 297MHz ARM frequency and 243MHz DDR frequency.
you are right that the textoverlay plugin is a cpu hungry plugin. I'm looking forward to see your results without the alpha blending under the text. This would be very interesting.
performing instruction to maximize the clock rate for DM368 (http://designsomething.org/leopardboard/f/33/p/615/2309.aspx#2309), this is the result of PLLs' and clocks' check:
cat /proc/davinci_clocks
