Re: [osg-users] People currently using the ffmpeg/libavcodec plugin?

[Raymond de Vries]

Hi,

I am curious, please keep us updated.

By any chance, are you also working on the audio part of it? It would be 
nice to have the audio as a stream for instance so it can be used as 
spatial audio.


Cheers,
Raymond

to be able to decode 8k x 8k streams.

I don't know why it wasn't merged.  I can't remember what
conversations were had.

Let us know what you think of it ours, and I think you're free to
merge it in if it works for people.

Re: [osg-users] [osganimation branch] Review, test, critics

[Raymond de Vries]

Hi Julien,

Thanks for sharing. I will look at it this week, hopefully others can 
jump in too.


Cheers,

Hi
I'm a bit concerned about the nathan.osg compatibility with RigTransHW..
I attached in my last a modified version of nathan (without shared ss) that 
should work (and so would replace the current one in osgdata).

I would be glad if Raymond (or other) could validate this model (ideally under 
win32) with the following tests
softwaretest : osganimationviewer nathan2.osg
HWtest:  osganimationhardware --number 1 nathan2.osg
(Don't forget I changed the maxnumbones type from int to uint in skinning.vert )
Once these tests validated elsewhere than my computer, It will confort me in 
the validity of the branch so i can make PRs to master (and to osgdata).

Cheers

I have not seen any issues in our own use of the osgAnimation. We tested in a 
few different setups and all seems ok.

The only thing is that the example did not work for me with Visual Studio 2015, 
while it does work for Julien.



Thanks for the testing.


Julian, if you feel osganimation is now ready could you generate a PR for the 
branch and I'll go ahead and merge it.


Cheers,
Robert.

[osg-users] measuring a frame

[Trajce Nikolov NICK]

Hi Community,

I am trying to measure the time needed to process a frame. My first and
somewhat naïve approach is to init the timer at the beginning of the frame
and get the result after the renderingTraversal. But, it seams (and that is
what I believe it is happening) the rendering traversal is containing the
swap buffers which is synced with the refresh rate (please correct me if I
am wrong). Is there something like preswap callback or something like this?

Thanks a bunch as always !

Cheers,
Nick
