d77fe9495a v4l2videodec: Fixes three H.264/HEVC ITU conformance tests
Postpone the cleanup of any consecutive sequence of lost frames
which starts at frame 0, until frame 100 is dequeued from driver.

This allows fluster tests JVT/CVWP2_TOSHIBA_E, JVC/CVWP3_TOSHIBA_E
and HEVC/POC_A_Bossen_3 that sends out-of-order frames to successfully
complete  (e.g., test of Amphion vpu driver).

Fixes #1569

e76e98d109 v4l2videodec: add cap negotiation fail check in the capture configuration change
The capture configuration change may cause negotiation fail.
Need to check it to avoid enter the endless loop.

735723c230 v4l2videodec: replace multiple decoder bug warnings with single one
Achieve this by dropping frames after a drain if the driver failed to so.
This works around RaspberryPi driver issue [1].

7c40fcb66e v4l2videodec: Fix activation of internal pool
If the driver does not support VIDIOC_CREATE_BUFS ioctl, the pool
configuration may get changed, which requires a validation. This would
fail to activate a pool in a case it shouldn't normally fail unless we
are out of memory.

6d6ebbbb36 v4l2videodec: Fix missing handling of resolution-change
The pool process function may poll and get the resolution-change event
whenever it is not possible to share our buffers. This typically happen
when downstream does not support GstVideoMeta.

Not handling this would cause the decoder thread to exit silently and the
pipeline to stall.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.

24eb35f113 v4l2videodec : enable resolution change
The dynamic resolution changes when
the sequence starts when the decoder detects a coded frame with one or
more of the following parameters different from those previously
established (and reflected by corresponding queries):
1.coded resolution (OUTPUT width and height),
2.visible resolution (selection rectangles),
3.the minimum number of buffers needed for decoding,
4.bit-depth of the bitstream has been changed.

Although gstreamer parser has parsed the stream resolution.
but there are some case that we need to handle resolution change event.
1. bit-depth is different from the negotiated format.
2. the capture buffer count can meet the demand
3. there are some hardware limitations that the decoded resolution may
be larger than the display size. For example, the stream size is
1920x1080, but some vpu may decode it to 1920x1088.

fe56af607b v4l2videodec : refactor the setup process of capture
v4l2videodec do some refactoring so that it can support
dynamic resolution change event.

1.wrap the setup process of capture as a function,
as decoder need setup the capture again when
dynamic resolution change event is received.

2.move the function "remove_padding"

01857d7941 v4l2videdec: Fix race condition between drain and state changes
This is due to an unsafe usage of the pad task. We didn't ensure proper
ownership of the task. That race involved the task being released too early,
and was detected, luckily, by the glib mutex implementationt that
reported the mutex being disposed while being locked.
