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

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
