27c1aa544e omx: don't log error when failing to load conf file with generic target
The generic target is meant to only test building gst-omx. It doesn't
provide any configuration file and so is not supposed to register any
element.
I'm not aware of any user building gst-omx with this target and
providing their own conf file to actually register elements. But best to
not break this use case anyway so let's just downgrade the log message.

Fix GST_ERROR in the 'check fedora' CI job.

If buffers were released from the pool while
gst_omx_video_enc_handle_frame() was waiting for new buffers,
gst_omx_port_acquire_buffer() was never awaken as the buffers weren't
released through OMX's messaging system.

d2f7e21ab9 omx: call gst_omx_buffer_unmap() when handling BUFFER_DONE
When using a input buffer pool, the buffer may be released to the pool when
gst_omx_buffer_unmap() is called. We need to have buf->used unset at
this point as the pool may use it to check the status of the pool.

{Empty,Fill}BufferDone is called from OMX internal threads while
messages are handled from gst elements' thread. Best to do all this
when handling the message so we don't mess with OMX threads and keep
the original thread/logic split.

40ae47df5e omx: wait for flush complete and buffers being released when flushing
When flusing we should wait for OMX to send the flush command complete event
AND all ports being released.
We were stopping as soon as one of those condition was met.

Fix a race between FillThisBufferDone/EmptyBufferDone and the flush
EventCmdComplete messages. The OMX implementation is supposed to release
its buffers before posting the EventCmdComplete event but the ordering
isn't guaranteed as the FillThisBufferDone/EmptyBufferDone and
EventHandler callbacks can be called from different threads (cf 2.7
'Thread Safety' in the spec).

Only wait for buffers currently used by OMX as some buffers may not be
in the pending queue because they are held downstream.

9a8e863862 omxvideodec/enc: add hack updating nBufferCountActual before allocating
The OMX specs states that the nBufferCountActual of a port has to default
to its nBufferCountMin. If we don't change nBufferCountActual we purely rely
on this default. But in some cases, OMX may change nBufferCountMin before we
allocate buffers. Like for example when configuring the input ports with the
actual format, it may decrease the number of minimal buffers required.
This method checks this and update nBufferCountActual if needed so we'll use
less buffers than the worst case in such scenarios.

SetParameter() needs to be called when the port is either disabled or
the component in the Loaded state.

Don't do this for the decoder output as
gst_omx_video_dec_allocate_output_buffers() already check
nBufferCountMin when computing the number of output buffers.

On some platform, like rpi, the default nBufferCountActual is much
higher than nBufferCountMin so only enable this using a specific gst-omx
hack.

3498f81d1f omx: always consider component in 'invalid' state when an error occured
gst_omx_component_get_state() used to early return if there was no
pending state change. So if the component raised an error it wasn't
considered in the invalid state until the next requested state change.

Fix this by checking first if we received an error.

2ca3cf5cfa omxvideodec: add hack to pass color format from caps to OMX decoder
This hack tries to pass as much information as possible from caps to the
decoder before it receives any buffer. These information can be used by
the OMX decoder to, for example, pre-allocate its internal buffers
before starting to decode and so reduce its initial latency.

This mechanism is currently supported by the zynqultrascaleplus decoder.

65cc312aa8 add OMX_PERFORMANCE debug category
Can be used to log buffers exchange between OMX and gst-omx to profile

Ideally this should be done using tracer hooks but it's currently not
possible to define custom hooks outside of core.

Use GST_DEBUG="OMX_PERFORMANCE:8" to enable it.

da07a647b8 omx: add API to implement dynamic buffers support
OMX 1.2.0 introduced a third way to manage buffers by allowing
components to only allocate buffers header during their initialization
and change their pBuffer pointer at runtime.
This new feature can save us a copy between GStreamer and OMX for each
input buffer.

This patch adds API to allocate and use such buffers.

4c0a8a6d90 gst_omx_port_set_flushing: simplify waiting loop
No semantic change so far, I just made the 'while' end condition easier
to understand as a first step before changing it.
- move error/time out checks inside the loop to make it clearer on what
we are actually waiting for.
- group port->buffers checks together with parenthesis as they are part
of the same conceptual check: waiting for all buffers to be released.
