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 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
This fixes a race condition that happened when seeking
very often in a short period of time.

Sebastian Dröge e56cff5f2a omxvideoenc: Fix minor race condition when draining after upstream signalled EOS 2011-11-10 15:01:36 +01:00
Sebastian Dröge 56bcfc0397 omxvideoenc: Improve EOS handling
If downstream return UNEXPECTED we should still signal the
drain cond because nothing will trigger this again later.

Sebastian Dröge de7d237851 omxvideoenc: No need to signal the drain cond when going from READY to PAUSED
Also the component is not started in READY.

Sebastian Dröge fb5d700ec9 omxvideoenc: Release the video codec stream lock before acquiring an input buffer
Otherwise the srcpad task might block on this lock and
no buffers ever become available again.

Sebastian Dröge 2d6239678f omxvideoenc: Don't try to drain the component after EOS
And don't send EOS twice in any case. This most likely
will cause the component to not output it again and
is not necessary anyway.

Sebastian Dröge ef67a43702 omxvideoenc: Better handling of encoder parameters

Sebastian Dröge 7ebef2941b omxvideoenc: If no stride was set for the OMX input port assume GStreamer stride
This is not really correct but there's nothing else we could do.
2011-11-02 10:39:10 +01:00
Sebastian Dröge 8eaf25c10e omxvideoenc: Implement draining of the component and use it
This makes sure that all buffers are encoded and pushed downstream
before flushing the ports and losing some buffers.

Sebastian Dröge e364088596 omxvideoenc: Switch to Idle first and wait before switching to Loaded and deallocating buffers
Allocating buffers before the Idle state is reached can lead to crashes.

Sebastian Dröge d5452a53b0 omxvideoenc: Add some more checks for correct OMX buffer sizes 2011-09-23 17:04:14 +02:00
Sebastian Dröge f0fe1148b7 omx: Wait until the Executing state is reached before calling OMX_FillThisBuffer()
This correctly works around the QCOM race condition that happens when calling
FTB after setting the new state and before reaching it.

Sebastian Dröge 9eb39ceef2 omxvideoenc: Release basevideocodec stream lock while waiting for a buffer
This prevents deadlocks if no empty input buffers are available and
releasing input buffers requires the loop function to handle some
output buffers first.

Sebastian Dröge 75c843670f omxvideoenc: Use "video/x-raw-yuv" as sink template caps instead of strict I420 caps 2011-08-10 10:24:48 +02:00
