0cb32a4ebd omx: Improve debugging of buffer handling 2011-12-05 13:18:09 +01:00
Sebastian Dröge
47d66cadfa omx: Only disabling of a port is like flushing, enabling is like unflushing 2011-11-17 14:38:54 -08:00
Sebastian Dröge
c144ebd054 omx: Enabling/disabling a port is also like flushing 
The component returns all buffers to us and shouldn't get any
new buffers passed anymore.

70b735da82 omx: Fix debug level for flushing in wrong state from ERROR to DEBUG 
It's not really an error and doesn't matter at all if flush is called
when the component is not running.

b66fd610d6 omx: Always reset buffer flags for output ports, even in flushing/error state 2011-11-09 15:41:02 +01:00

1d071c05dc omx: Also properly release buffers when in error state 2011-11-08 08:24:49 +01:00

0682012181 omx: Properly release buffers during flushing 
We can't pass them back to OMX_FillThisBuffer() or OMX_EmptyThisBuffer()
but instead of doing nothing we have to put them back into our queue.
Otherwise the buffer is leaked and we will have too few buffers in
the future.

fa6881c1cc omx: Reset buffer flags to 0 after it was consumed by the component or the element 
Some implementations don't reset the flags and the standard is not
really clear on the expected behaviour. Let's just always reset the
flags as they're not valid at this point anymore.

72fa93956b omx: Remove QCOM hack to reset nOffset in EmptyBufferDone 
This is now done in a generic way that does not require any
hacks because it will work without any side effects on any
OMX implementation.

2750a8869b omx: Reset nOffset to 0 in EmptyBufferDone if nFilledLen is 0 
Some OMX implementations don't reset nOffset when the complete
buffer is emptied but instead only reset nFilledLen. We reset
nOffset to 0 if nFilledLen == 0, which is safe to do because
the offset *must* be 0 if the buffer is not filled at all.

Seen in QCOM's OMX implementation.

837fc4ca66 omx: Add hack for Qualcomm's OMX implementation to manually reset nOffset in EmptyBufferDone 2011-09-26 13:05:23 +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.

9dcaf5c2bb omx: Don't hold any locks while calling OMX_SendCommand() 
It might call into one of the callbacks and lead to deadlocks, e.g.
with the Qualcomm OMX implementation.

8fd4eaae69 omx: Set pAppPrivate of buffers to NULL when deallocating buffers 
This prevents usage of freed memory later if the OMX component
has weird behaviour.

9e1cfa300b omx: Deallocate port buffers before freeing the component 
They should be deallocated by the caller before reaching the
Loaded state but to be on the safe side we will make sure
they're really deallocated here.

db08890edd omx: Rework port reconfiguration 
We always reconfigure all ports now if the settings of one
port changes to prevent lots of race conditions, dropped
frames and similar issues.

c8c1c7f10f omx: Add more checks to acquire_buffer() and return the current state additional to the buffer 
Also refactor the code flow in the video decoder for this. This makes
the usage of acquire_buffer() easier and more atomic.

28688414b8 omx: Don't broadcast port->port_cond after allocating buffers successfully 
Allocating buffers must happen while no thread is waiting for the
cond and especially must happen from the thread that would acquire
buffers from the port.

d9e2391448 omx: Always check if the component is in an error state before waiting for a condition variable to be signalled 
Otherwise we might wait forever because nothing is going to signal
the condition variable anymore.

46fe757270 omx: Always hold port->port_lock before signalling port->port_cond when notifying about errors 
Otherwise a port might be in the critical section, has checked the error state
already but waits after port->port_cond is signalled, which will lead
to a deadlock.

5d4f7890c2 omx: Don't use port_def.bEnabled to check if the Enable/Disable command is finished 
bEnabled should be set immediately after sending the command, it's only
Bellagio that waits until the command is finished before setting it.

bc1e73e8c8 omx: Add initial version of OpenMAX framework, video decoder base class and MPEG4 video decoder 
This currently hardcodes a lot of stuff but works at least.

Also adds a generic framework for handling OpenMAX cores, components
and ports.
