George Kiagiadakis 158775f497 Implement a new custom recursive mutex type and fix locking in callbacks so that in-context calls are allowed. 
According to the OMX specification, implementations are allowed to call
callbacks in the context of their function calls. However, our callbacks
take locks and this causes deadlocks if the unerlying OMX implementation
uses this kind of in-context calls.

A solution to the problem would be a recursive mutex. However, a normal
recursive mutex does not fix the problem because it is not guaranteed
that the callbacks are called from the same thread. What we see in Broadcom's
implementation for example is:

- OMX_Foo is called
- OMX_Foo waits on a condition
- A callback is executed in a different thread
- When the callback returns, its calling function
  signals the condition that OMX_Foo waits on
- OMX_Foo wakes up and returns

The solution I came up with here is to take a second lock inside the callback,
but only if recursion is expected to happen. Therefore, all calls to OMX
functions are guarded by calls to gst_omx_rec_mutex_begin_recursion() / _end_recursion(),
which effectively tells the mutex that at this point we want to allow calls
to _recursive_lock() to succeed, although we are still holding the master lock.

Sebastian Dröge 3db75118dd omxvideoenc: Remove workaround for basevideocodec bug 2011-12-12 14:26:48 +01:00
Sebastian Dröge 9e6665e8f8 omx: Add hack for encoder components that don't allow empty EOS buffers 2011-12-09 12:24:01 +01:00
Sebastian Dröge bd60f141e9 omxvideoenc: Use correct timestamp, duration and filled length for the EOS buffers 2011-12-06 12:46:51 +01:00
Sebastian Dröge 781e61d569 omxvideoenc: Drop EOS events in ::finish() 
The event will be forwarded downstream from the srcpad
loop function after the last buffer was generated by the
component. Forwarding it after ::finish() will use the
sinkpad streaming thread and does not guarantee that
the encoder is completely drained.

Sebastian Dröge be4e1e184e omxvideoenc: First set ports to flushing before waiting for the srcpad streaming thread to finish 2011-11-18 09:59:43 -08:00
Sebastian Dröge 1ba8ec3d37 omxvideoenc: Signal the drain GCond even if downstream returned an error 2011-11-17 11:29:39 -08:00
Sebastian Dröge 2408e0d33a omxvideoenc: Shutdown component in PAUSED->READY and deallocate buffers 2011-11-17 10:19:47 -08:00
Sebastian Dröge 879349ba11 omxvideoenc: Set force_keyframe to FALSE after handling it 
There's no reason why the base class should forward the event
further downstream if we already handled it and will insert a
keyframe.

Sebastian Dröge 22ba4e1b9e omxvideoenc: Add vfunc for handling the output frames 
This can be used by subclasses to override the buffer flags
or to handle some frames differently than the default behaviour.

Sebastian Dröge fbe171ee2c omxvideoenc: Always flush the ports and make sure no processing is happening in ::reset

very often in a short period of time.
