[osg-users] ffmpeg plugin : play a video frame by frame
Hi everybody, i'm wondering if is it possible to use ffmpeg plugin with OSG 3.0.1, to play a video frame by frame. I compiled osg 3.0.1 with ffmpeg plugin, and i run the osgmovie example with no problem. Now, what i'd like to do, is to play a video frame by frame : i would say to my application (using ffmpeg or other video plugin), to visualize a specific frame. I read the seek method into osg::imagestream. So i wrote the following code: // Note 1: mImagestream is the imagestream associated to video // Note 2: framenum is the frame number to visualize double duration=mImagestream->getLength(); double frame_rate=mImagestream->getFrameRate(); ... double frameTime=1/frame_rate; double t_pos =framenum*frameTime; mImagestream->seek(t_pos); mImagestream->play(); mImagestream->pause(); ... Nothing happens. Are there some suggestions? Thank you!

Re: [osg-users] ffmpeg plugin
Hello, Mourad, Thanks for the tips. It turned out I did leave one FFMPEG related line unfilled in CMake configuration, FFMPEG_STDINT_INCLUDE_DIR. I looked up past conversations on OSG mailing list and found the place to download the two header files that this line was intended to create a path to. After doing that, I was able to get the VS project created. Then I ran into the issue with the new FFMPEG libraries but was able to solve it with the fix that Wang Rui submitted earlier this week.

Re: [osg-users] ffmpeg-plugin does not recognize .ogv extension
Hi Ari,
Just add the supportsExtension("ogv",""Theora movie format"); into the
ReaderWriterFFmpeg.cpp and see if that works fine for you. If it
does then send the change to osg-submissions ;-)

[osg-users] ffmpeg-plugin does not recognize .ogv extension
Hi!
I think I found a little issue with ffmepg plugin. According the source
files Xine plugin supports .ogv extension (only) and ffmpeg plugin
supports .ogg (only).
It seems that .ogv is now official extension for video.:
http://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions
ReaderWriterFFmpeg.cpp:
supportsExtension("ffmpeg", "");
supportsExtension("avi","");
supportsExtension("flv","Flash video");
supportsExtension("mov","Quicktime");
supportsExtension("ogg","Theora movie format");
supportsExtension("mpg","Mpeg movie format");
supportsExtension("mpv","Mpeg movie format");
supportsExtension("wmv","Windows Media Video format");
supportsExtension("mkv","Matroska");
supportsExtension("mjpeg", "Motion JPEG");
supportsExtension("mp4","MPEG-4");
supportsExtension("sav","MPEG-4");
supportsExtension("3gp","MPEG-4");
supportsExtension("sdp","MPEG-4");
I used hours wondering why ogv example that comes with Ubuntu 10.4 worked
with xine plugin but not with ffmpeg plugin.

[osg-users] ffmpeg plugin on osx
Hi, Has anybody compiled ffmpeg sucessfully to work with osg-2.8.3-rc2? When building the osgmovie example I keep getting the attached linker errors no matter how I seem to compile ffmpeg. I tried both i386 and x86_64, building everything from scratch. I have a feeling though the ffmpeg configure script is ignoring the arch flag or I am doing it wrong. I even tried setting the flags like this without much luck. LDFLAGS="-arch i386" CFLAGS="-isysroot /Developer/SDKs/MacOSX10.5.sdk -arch i386" Any ideas. Hope this is not too offtopic here.

Re: [osg-users] FFmpeg plugin
HI Carlos,
As I don't see any of these problems, I'm afraid there isn't much I can do
apart from make suggestions for you to try out. Right now it looks like
you'll need to add the zlib library into the build of other ffmpeg or our
plugin.

Have a look in ffmpeg itself for the inflateInit_ method. Another thing
you could try is using the svn version of ffmpeg, or the ffmpeg libs pulled
down from the Ubuntu repositories.

Re: [osg-users] FFmpeg plugin
Hi Carlos,
What happens when you run:
osgmovie -e ffmpeg a_video.mpg
Is it still reporting that it can't load the plugin?
I suspect that you are still hitting against the plugin not loading
correctly. The inflatInit method is still being reported as not found and
this function is from zlib then ffmpeg is built without linking against zlib
which is needs. Linking against zlib ourselves in our ffmpeg could a
solution.
It's odd that you're having problems wheras others aren't. What is the
exact spec of your system?
Robert.

Re: [osg-users] FFmpeg plugin
ok , now i m using svn version of ffmpeg.
bow the example runs but the message still apear
I put the the lines in main function of my program::
std::string libName = osgDB::Registry::instance()->
createLibraryNameForExtension("ffmpeg");
osgDB::Registry::instance()->loadLibrary(libName);
but looks like that its using xine yet .
and the old error continues.

ok, I have the ffmpeg installed . I use it to convert my movies.
Now I m seeing in ccmake configure list . but have some options that I

the options are :

Re: [osg-users] FFmpeg plugin
HI Carlos,
Our plugin doesn't contain any inflateInit_ or inflate method of any kind,
so the missing sybmol must be coming from ffmpeg itself. I haven't see this
error myself when building from various versions of ffmpeg so perhaps it's
version 0.5 that has gone astray.
Have a look in ffmpeg itself for the inflateInit_ method. Another thing you
could try is using the svn version of ffmpeg, or the ffmpeg libs pulled down
from the Ubuntu repositories.

You have to donwload ffmpeg and build the plugin by setting up the right
parameters in cmake. then osg will build the ffmpeg plugin as well as the

I m seeing that my /usr/local/lib/osgPlugins-2.9.1 directory dont have
the plugin for ffmpeg .
this is correct ?
I put this in my code ...
std::string libName =
osgDB::Registry::instance()->createLibraryNameForExtension("ffmpeg");
osgDB::Registry::instance()->loadLibrary(libName);
but how I know if it is using ffmpeg ?

Re: [osg-users] FFmpeg plugin
Hi Carlos
You have to donwload ffmpeg and build the plugin by setting up the right
parameters in cmake. then osg will build the ffmpeg plugin as well as the
other 3rd party plugins will be build.

[osg-users] ffmpeg plugin streaming video proof of concept
Hi All,
We now have the beginnings of the ffmpeg checked into svn/trunk, and
my hope is that this might one day get capable enough to replace the
existing xine-lib plugin and quicktime plugins as the source of video
support. Just having one video backend would help with maintenance as
well enabling a full feature set across all platforms, but this will
only be possible if we can get the new ffmpeg working well across all
platforms with all the original functionality. One item that the
quicktime plugin has is stream support under Windows and OSX, so...
this is also one of the items that needs to be added if possible.
The "if possible" question is something that I wanted to explore, and
various code fragments on the web suggested that it was possible, so
I've hacked together a proof of concept extension to the ffmpeg so
that it attempts to open a video device as input. This didn't
actually take too long to try out, so under linux you can now do:
osgmovie -e ffmpeg /dev/video0
Which if you have a webcam or similar device on /dev/video0 it'll open
it up using video4linux2 and stream it, full screen.
The proof of concept is only a dozen lines of code so far, with
defaults chosen that work fine for my hardware/OS setup. For other
OS's the settings will certainly be different, and it's not entirely
clear to me that ffmpeg does support such device streaming across all
platforms... More investigation will be required. Please dive in to
ffmpeg docs/online discussions to see if you can spot the approach to
take under Windows + OSX etc.
For a final incarnation of live video streaming support we'll need to
add controls for the various device parameters, either via parsing of
ReaderWriter::Options strings, or extended Options to include
appropriate device parameters. We will probably need some kind of
scheme for querying the device options available too. I really don't
have much of clue how we might go about all this yet as it's very
early days for me delving into this side of things.
For those interested in helping out with development of the streaming
support have a look at the code I just added to
src/osgPlugins/ffmpeg/FFmpegDecode.cpp, in particular the bool
FFmpegDecoder::open(const std::string & filename) method:
if (filename.compare(0, 5, "/dev/")==0)
{
avdevice_register_all();
osg::notify(osg::NOTICE)<<"Attempting to stream

Already fixed this. I've been testing 3 different revisions of ffmpeg and got both swscale and img_convert paths working out the box. However I am getting a black band on the right hand side of the image when swscale code path is used and poorer visual quality.

I've previously worked with the same ffmpeg revision as the one you are using, but it's obviously been built differently as it does have img_convert.In later rev's ffmpeg drops the img_convert from the header, but still implements it. The swsscaler functions are also implemented but the headers aren't installed unless you compile the libswscale library. It really is a bit of mess. I find it a bit bizarre that ffmpeg seems to do a good job at what it does but... packaging consistency really does it a disservice.

Yup. That solves the #include problem.
What I'm currently looking at is 'undeclared INT64_C' in 'FFmpegDecoderVideo.cpp' which is
caused by some header including stdint.h without '#define __STDC_CONSTANT_MACROS'.
I can solve this by including 'FFmpegHeaders.hpp' first thing in 'FFmpegDecoderVideo.hpp'
(see attachment). Does that work on Linux?
After that it's the missing libpath to find libavformat and friends. I've added some code
to 'FindFFmpeg.cmake' to extract the library directories but have now idea yet how to tell
cmake to use that path in src/osgPlugin/ffmpeg/CMakeFiles ...

This change would break other systems as they don't have all have the
ffmpeg prefix. When I have built ffmpeg from source the ffmpeg prefix
doesn't exist but has the libavformat (etc.) prefix, but when I check
it out from ubuntu repositories it did include the ffmpeg prefix, but
no libavformat (etc.) prefix. To handle the differences I've already
introduced some extra paths in the Cmake setup, but clearly we'll have
to go further.
I've have now added the ffmpeg to the include search paths so the set
up code looks like:
INCLUDE_DIRECTORIES(
${FFMPEG_LIBAVFORMAT_INCLUDE_DIRS}
${FFMPEG_LIBAVFORMAT_INCLUDE_DIRS}/libavformat
${FFMPEG_LIBAVFORMAT_INCLUDE_DIRS}/ffmpeg
${FFMPEG_LIBAVDEVICE_INCLUDE_DIRS}
${FFMPEG_LIBAVDEVICE_INCLUDE_DIRS}/libavdevice
${FFMPEG_LIBAVDEVICE_INCLUDE_DIRS}/ffmpeg
${FFMPEG_LIBAVCODEC_INCLUDE_DIRS}
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}/libavcodec
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}/ffmpeg
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}/libavcodec
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}/ffmpeg
)
Could you do an svn update and see if this addition helps things.
Robert.

Re: [osg-users] ffmpeg plugin on OS X / DarwinPorts
Hi Ulrich, The print out of the FFMPEG_INCLUDE_DIRS and FFMPEG_LIBRARIES is a bit misleading, as it is actually composed on separate strings like CMake picks up on correctly when passing it to macros that set up paths, but when you output these variables to the console they get concatenated together. To see what is be compiled against do: cd src/osgPlugins/ffmpeg make VERBOSE=1 What errors do you see some errors in the compilation? What version of the ffmpeg are you using? Robert.

[osg-users] ffmpeg plugin on OS X / DarwinPorts
Hi all, is anyone else using DarwinPorts ffmpeg/avcodec/avformat and was successful in compiling the plugin? Apparently there's a problem between pkg-config and cmake, "cmake" is giving me: FFMPEG_INCLUDE_DIRS = /opt/local/include/opt/local/include/dirac FFMPEG_LIBRARIES = avformatavcodeczbz2a52faacfaadmp3lameschroedinger-1.0pthreadoil-0.3xvidcoredirac_encoderdirac_decoderstdc++theoravorbisencavutilvorbismogg It's stringing the different include paths and libraries together which of course doesn't work. pkg-config looks good: $ pkg-config --cflags libavformat -I/opt/local/include -I/opt/local/include/dirac $ pkg-config --libs libavformat -L/opt/local/lib -lavformat -lavcodec -lz -lbz2 -la52 -lfaac -lfaad -lmp3lame -lschroedinger-1.0 -lpthread -loil-0.3 -lxvidcore -ldirac_encoder -ldirac_decoder -lstdc++ -ltheora -lvorbisenc -lavutil -lvorbis -lm -logg Anyone?
