4e834dfc73 From Brad Christiansen, "Attached are some small changes to the ImageStream interface and the DirectShow and FFMPEG plugins to provide the current time being displayed in the image stream.
I don’t have access to an OSX or Linux dev machine to make the changes required to the quick time plugin. This plugin will just default to returning 0."

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."

a1639c3d2d From Brad Colbert, "Added a new method to ImageStream called getLength that is used to
return the length of the stream.

Implemented the virtual methods in QuicktimeImageStream, (getLength,
getReferenceTime, setTimeMultiplier), to return valid value for each.
