[Buildroot] [PATCH v3 1/2] libimxvpuapi: add new package

[Gary Bisson]

This is a library for using the i.MX6 VPU. It is an alternative to
libfslvpuwrap, hosted on Github, and has an API that features several
improvements over libfslvpuwrap, which include:

* User-defined context information associated with input frames, which
is passed on to corresponding output frames (to be able to identify
which input frame produced which output frame)
* Groundwork for future DMA-BUF/BMM/ION/CMA allocator integration, using
file descriptors instead of physical addresses
* Indicators for when it is safe to try to decode frames, which is
critical in multi-threaded playback cases
* Simplified, higher-level JPEG en/decoding API, based on the VPU MJPEG
codec; useful for picture viewing without the extra boilerplate for
VPU-based en/decoding

Changelog 0.10.0 -> 0.10.1:
- add debian packaging files
- update waf to version 1.8.16
- add workaround in wscript to prevent stale pkg-config .pc files
- fix memory leak by adding missing IOFreeVirtMem() call in vpulib
backend

This patch is based on the Yocto equivalent:
https://github.com/Freescale/meta-fsl-arm/commit/e519d6c
https://github.com/Freescale/meta-fsl-arm/commit/1dd6a5b

This package has been implicitely tested through gstreamer as the
plugins rely on it for vpu decoding:
 # gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm

Signed-off-by: Gary Bisson <gary.bisson@boundarydevices.com>

Changelog v1->v2:
- add hash file
- add upstream URL
- change license to LGPLv2.1+
Changelog v2->v3:
- none

Thanks,
Gary

[Buildroot] [PATCH v3 2/2] gst1-imx: bump to version 0.12.0

[Gary Bisson]

Changelog:
* vpu:
  - Completely rewritten plugin code; elements now based on libimxvpuapi
    instead of libfslvpuwrap
  - imxvpuenc_h264 inserts SPS/PPS data in front of I/IDR frames
  - imxvpuenc_mjpeg's quality factor actually has an effect, and is
    equivalent to the libjpeg's quality factor (it is used in exactly
    the same way to scale the quantization matrix' coefficients)
  - the encoder's output buffers no longer have to use DMA memory; they
    use regular system memory instead
  - new support in imxvpudec (referred to as "chroma interleaving") for
    NV12, NV16, NV24 as output formats as an alternative to the I420,
    Y42B, Y444 formats
  - removed all of the system frame number tracking code, since it is
    unnecessary; Instead, the libimxvpuapi's context fields are used to
    associate input/output frames with GstVideoCodecFrame system frame
    numbers
  - fix memory leaks related to missing buffer pool unref'ing

* imxv4l2videosrc:
  - support for crop metadata
  - element uses the width, height, etc. of the format that the device
    actually uses during operation (instead of default values)
  - autofocus control support via GstPhotography
  - fix incorrect GLib warnings
  - fix segmentation fault when shutting down the element

* eglvivsink:
  - remove extra g_free() calls, which lead to runtime errors
  - remove GLESv2 VIVANTE link dependencies
  - add Android platform
  - manually retrieve VIV direct texture functions
    with this and the link dependency elimination, this means that for
    platforms except the framebuffer one, no Vivante specific headers
    and libraries are needed anymore
  - fix blocking issue in the Wayland platform mainloop

* improved and expanded documentation

* pxp: NV16 *is* supported after all (it was actually a bug in GStreamer
pre-1.5.91)
NOTE: this does not break compatibility with GStreamer versions older
than 1.5.91

* compositor: Update backported aggregator code to GStreamer 1.6

* blitter:
  - error handling improvements
  - add missing buffer pool unref'ing, which lead to memory leaks
  - add missing compositor dependency to blitter base

* uniaudio:
  - only build the uniaudio plugin if at least one codec was found
    during configuration
  - disable plugin if the gstaudio library is not available
  - add AAC profile field to the sink caps with GStreamer >= 1.4.4 to
    ensure the uniaudio decoder is only used for AAC-LC data

* ipu: increase fill frame width from 8 to 64 pixels to make IPU fill
operations work with pre-3.14 Freescale kernels

* g2d: use padding pixels when setting surface parameters, fixing G2D
failures with frame sizes that aren't aligned

* wscript:
  - improve Android support
  - fix installation paths for the common, blitter, compositor libraries

This is based on the Yocto equivalent:
https://github.com/Freescale/meta-fsl-arm/commit/cf7a088

However this package now offers a more flexible approach because it can
be built without the GPU or VPU elements for devices based on SoCs that
lack those features like the new i.MX7.

Tested with the following commands on i.MX6Q (IPU):
 # gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm
 # gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
   matroskademux ! imxvpudec ! imxipuvideosink
 # gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
   matroskademux ! imxvpudec ! imxeglvivsink

Tested with the following commands on i.MX6SX (PXP):
 # gst-launch-1.0 imxv4l2videosrc device=/dev/video1 ! imxpxpvideosink
