74a9ccb49d From David Fries, merge from a series of related submission emails:
"enable thread locking in libavcodec

This is required for a multithreaded application using ffmpeg from
another thread."

"Prevent the audio from videos from hanging on exit if they are paused.
The video decoder already has similar logic."

"Add a way to retrieve the creation time for MPEG-4 files."

"fmpeg, improve wait for close logic

Both audio and video destructors have been succesfully using the logic,
if(isRunning())
{
  m_exit = true;
  join();
}
since it was introduced,

but the close routines are using,
m_exit = true;
if(isRunning() && waitForThreadToExit)
{
  while(isRunning()) { OpenThreads::Thread::YieldCurrentThread(); }
}
which not only is it doing an unnecessary busy wait, but it doesn't
guaranteed that the other thread has terminated, just that it has
progressed far enough that OpenThreads has set the thread status as
not running.  Like the destructor set the m_exit after checking
isRunning() to avoid the race condition of not getting to join()
because the thread was running, but isRunning() returns false.

Now that FFmpeg*close is fixed, call it from the destructor as well
to have that code in only one location."

0816d4f9cd From Magnus Kessler, "FFmpeg headers need __STDC_CONSTANT_MACROS defined before stdint.h is loaded.
The file FFmpegHeaders.hpp sets this definition. However, if stdint.h is
already included through other files, it won't take any effect.

Include FFmpeg headers as early as possible in order to avoid stdint.h being
included on other paths.

c5c71f519c From Serge Lages, "Here is a little fix for the FFmpeg plugin. Previously the path computed by osgDB::findDataFile was not used, preventing loading files from directories inside the data path list." 2009-06-25 13:10:31 +00:00

3c4fc747ff From Ulrich Hertlein, "I got the following type error from gcc 4.0.1 on OS X 10.5.6:
/Users/uli/Projects/osg/OpenSceneGraph/src/osgPlugins/ffmpeg/FFmpegDecoderVideo.cpp: In member function \u2018int osgFFmpeg::FFmpegDecoderVideo::convert(AVPicture*, int, AVPicture*, int, int, int)\u2019:
/Users/uli/Projects/osg/OpenSceneGraph/src/osgPlugins/ffmpeg/FFmpegDecoderVideo.cpp:245: error: invalid conversion from \u2018int\u2019 to \u2018PixelFormat\u2019
/Users/uli/Projects/osg/OpenSceneGraph/src/osgPlugins/ffmpeg/FFmpegDecoderVideo.cpp:245: error:   initializing argument 3 of \u2018SwsContext* sws_getContext(int, int, PixelFormat, int, int, PixelFormat, int, SwsFilter*, SwsFilter*, double*)\u2019

It expects 'src_pix_fmt' and 'dst_pix_fmt' to be of type 'PixelFormat' rather than int. The attached cast fixes this (for me).

I've also added Matroska video to the list of supported extensions"
