It solves a wrong sample format being set for audiostreams type S32 and F32, for the
enum AVSampleFormat (in include/avutil/samplefmt.h) doesn't match
enum SampleFormat (in include/osg/AudioStream) for anything but
SAMPLE_FORMAT_U8 and SAMPLE_FORMAT_S16
"
and follow up that address versioning issue
"I can find the change, avutil version 50.38.0 introduced a new header file:
libavutil/samplefmt.h
older versions use
libavcodec/avcodec.h
with the sampleformats without AV_
an intermideate fix with the FF_API_OLD_SAMPLE_FMT is removed from ffmpeg 0.8.3 so
I think this is the correct fix:
#if LIBAVUTIL_VERSION_INT < AV_VERSION_INT(50,38,0)
#define AV_SAMPLE_FMT_NONE SAMPLE_FMT_NONE
#define AV_SAMPLE_FMT_U8 SAMPLE_FMT_U8
#define AV_SAMPLE_FMT_S16 SAMPLE_FMT_S16
#define AV_SAMPLE_FMT_S32 SAMPLE_FMT_S32
#define AV_SAMPLE_FMT_FLT SAMPLE_FMT_FLT
#define AV_SAMPLE_FMT_DBL SAMPLE_FMT_DBL
#define AV_SAMPLE_FMT_NB SAMPLE_FMT_NB
#endif
"
So with the 3.0 api change we propose the following change:
- put OSG_EXPORT on the QueryGeometry class so that we get access to the getNumPixels method.
- Create a function called getQueryGeometry that returns a casted _queryGeode->getDrawable(). Or a function called getQueryGeode that returns _queryGeode."
The osgUtil::CullVisitor class will display an OSG_INFO notification when attempting to clamp the projection matrix with invalid near/var values. This usually appears when the scene graph is empty or all objects are culled. I don't think this scenario warrants having this message appear every frame. It makes it very difficult to debug other issues when this notification floods the output window.
I'd prefer to have the notification removed, but there might be legitimate cases where you want this displayed. Instead, I just disabled the output if the near/far values are equal to FLT_MAX (their initial values). This should at least prevent the notification for the common case where everything was culled."
Line 251:
int getKeyEventWindowedResolutionDown() const { return _keyEventWindowedResolutionUp; }
Should be replaced with:
int getKeyEventWindowedResolutionDown() const { return _keyEventWindowedResolutionDown; }"
"Here a patch that correct like the previous assign collada material name
to stateset."
and
"I changed how the collada reader set object name in osg. Current
implementation use collada ID to setup name. with this patch I use
collada name to setup name in osg object and if collada provide no name
I use as fallback ID. I am not sure we want this fallback.
The motivation of this change is that when an artist set names to its
objects and export to collada, I am not able to use those names in osg
to retrieve the node."
and
"Here the update of the file that fix the light id stuff"
with the StatsHandler. When the 's' key is pressed, the rendering
window will be halted. I tried solving the problem by commenting a
line in CMFC_OSG_MDIView::OnKeyDown() and it seems to work now.
Another improvement here is to use a thread class derived from
OpenThreads to replace the old _beginthread(). It helps a lot in
keeping a high frame rate when you open more than one MDI child
windows. And the application using OpenThreads in my opinion will be
more compatible and portable."
Added COMPUTE_NEAR_FAR_USING_PRIMITIVES option that provides the original functionality where only the near plane
is computed in a fine grained way, with the far plane being computed simply from bound volumes.
