The number of planes is a meta we carry around in the GstVideoMeta with
DMA_DRM format. In cannot be decuded correctly from knowledge of the
base format. Notably, some compression modifier may introduce an extra
plane to store the compression parameters.
So use n_planes from GstVideoMeta and pass this explicitly when
importing to EGLImage.

The DMAbuf accept function was ensuring the in_dma_info values was valid if
the in_caps have change. But the check was bogus since the in_caps was being
modified without a pointer change. As a side effect, on the second accept
call, the drm_fourcc was reset to 0, which cause the uploader to fallback.
Fix this by ensuring we always have a valid dma_frm info directly in the
set_caps() function. Also remove the bogus caps changed check and remove any
modification to the info structure and always do that inner checks.

DRM Modifiers are not generically transferrable from a format like NV12 to
their indirect shading format (R8 / RG88). So the helper to this do needs
to be removed from our API.
To make things worse, we support indirect formats that aren't DRM format in
the first place. Notably NV12_16L32 (aka MM21) is not (yet) a DRM format. Yet,
each plane can be indirectly imported using R8/RG88 and a detiling shader.
This patch also removes this constraint restoring zero-copy playback on
Mediatek SoC.

With one regular image file path provided (without %05d),
the element was stuck in a dead loop counting the frames:
gst_image_sequence_src_count_frames
This allows to display any image file out of the element
for a given number of buffers.

Update connection-speed at runtime in playbin, uridecodebin and decodebin
also do the same thing in urisourcebin.

If the v4l2videoenc receives an QUERY_ALLOCATION, it must not propose a
currently used pool, because it cannot be sure that the allocation query came
from exactly the same upstream element. The QUERY_ALLOCATION will not contain
the internal OUTPUT pool.
The upstream element (the basesrc) detects that the newly proposed pool differs
from the old pool. It deactivates the old pool and switches to the new pool.
If there was a format change, a new OUTPUT buffer pool will be allocated in
gst_v4l2_object_set_format_full() and the CAPTURE task will be stopped to switch
the format. If there hasn't been a format change,
gst_v4l2_object_set_format_full() will not be called. The old pool will be kept
and reused.
Without a format change, the processing task continues running.
This leads to the situation that the processing task is running, but the OUTPUT
buffer pool (the old pool) is deactivated. Therefore, the encoder is not able to
get buffers from the OUTPUT pool and encoding cannot continue.
This situation can be triggered by sending a RECONFIGURE event without a format
change.
Resolve this situation by ensuring that the OUTPUT buffer pool is always
activated when frames arrive at the encoder.

There is a CAPTURE pool in the same function. While the CAPTURE pool is called
cpool, using pool for the OUTPUT pool is confusing.
Using opool for the OUTPUT pool makes it more obvious, which pool is used.

We were already converting the pad last timestamp to running time but
not the segment position.
This segment position is used by gst_aggregator_simple_get_next_time()
to compute the waiting time when aggregating.
Those waiting times were wrong in my live pipeline using the system
clock, resulting in the aggregator to never wait at all.

While adding arbitrary tile support, a round up operation was badly
converter. This caused the Y component of the stride to be 0. This
eventually lead to a crash in glupoad preceded by the following
assertion.
gst_gl_buffer_allocation_params_new: assertion 'alloc_size > 0' failed
