Panda3d with recent ffmpeg and openal (needs testing)

Compiling or Editing the Panda Source
1

update 2:

i got it running… at least i hear sound without fmod installed :slight_smile:

But… i only tried under osx leopard which does make quite some problems while trying to get it compiled (afaik messed up headers in /usr/include).

i have posted a updated patch below.

But this is still not ready for integration in panda3d, as i had to explicitely define HAVE_OPENAL in panda/src/pandabase/pandabase.h, if someone knows how to fix it?

update:

ppl trying to comile panda3d with ffmpeg and openal using ppremake will need to make the changes described in the following posts (ffmpeg changes & patch panda3d).

2

What’s the error message?

3

i haven’t tried ffmpeg yet (using macports currently does not build ffmpeg for me the last time i tried - 3 weeks ago).

but: panda3d builds out-of-the-box from cvs for me now. including Cg support, a multi-threaded version and even the panda tools do compile for me for Maya.

4

The error i’m getting is:

for the first problem:

Im not sure what im doing wrong, i now tried to manually compile the libparticlesystem (copying the g++ commands (make clean) and manually adding the parameter). It does compile, however that doesnt really seem to help, but actually i got to admin i dont really understand what this really does and how it could be fixed.
It just would be nice to have a packapanda for osx… :slight_smile:

What happens if you just create an empty C++ file and say

#include “ffmpeg.h”

in it, and nothing else? Does it compile?

6

— changes required in ffmpeg —

in /opt/local/include/ffmpeg/avformat.h:
after:
#define LIBAVFORMAT_IDENT       "Lavf" AV_STRINGIFY(LIBAVFORMAT_VERSION)
add:
#define INT64_C
#define __STDC_CONSTANT_MACROS
#include <stdint.h>

i found it here:
http://vskrishnan.wordpress.com/2007/07/31/ffmpeg-int64_c-problem-and-workaround/

Another problem i found is that it says integer to long for Long:

in /opt/local/include/ffmpeg/avcodec.h
change:
#define AV_NOPTS_VALUE          INT64_C(0x8000000000000000)
to:
#define AV_NOPTS_VALUE          INT64_C(0x8000000000000000LL)

– deprecated –

see last post for recent panda3d - diff

I’ll be happy to apply this patch to Panda, but I don’t understand why it is necessary to add avcodec.h etc. to pview and pgrid and all the other standalone executables. First, doing this will cause compile problems for people who don’t have ffmpeg installed and want to compile Panda without this library; but second, it shouldn’t even be necessary in the first place, since any code that directly uses avcodec.h should be responsible for its inclusion.

Do you know why this change is part of the suggested patch?

Hi,

actually im just trying around… It may not be necessary to include any additional headers which have not yet been included.

Still right now i dont recommend applying this patch as i have not even got it running myself, but it might be interesting if somebody from another OS checks it this patch works for himself using a recent ffmepg version.

I’ll try to continue my work, as i know the source of the problem, but im bit stuck because i dont know how to prevent it occuring… Maybe somebody more experienced developing on OSX could check this…

a new diff

i have now successfully compiled panda3d under osx, i also tried adding openal into ppremake, for osx the above changes to ffmpeg are still required.

Someone should try this with a recent ffmepg and openal under a os that actually is known to work with openal…

genPyCode works fine for me, but i still have the NullAudioManager as sound source (i changed the Config.prc to “audio-library-name openal_audio”)

renaming the lib as suggested doesnt seem to work for me:
libopenal_audio.so -> libp3openal_audio.so
libopenal_audio.dylib -> libp3openal_audio.dylib
SO DONT DO THAT

-> a new diff will be online soon… found some bad errors in it …
