Changelog:
==== version 0.13.0 (2017-11-01) ====
* New imxv4l2videosink element
Currently only supports input physically contiguous memory blocks
as input (so, for example, no videotestsrc)
* New Pango-based overlay elements using G2D for rendering
* gstimxcommon library is now public
Necessary when implementing external sinks to retrieve the mapped
physical memory address from gstreamer buffers
(NOTE: ABI may change in the next few releases until this is stabilized)
* New optional ability to use GstPhysMemory from gst-plugins-bad
* imxv4l2videosrc:
* Fix compile prior to Gstreamer 1.3.1
* v4l2_buffer_pool: Add special case for tw6869 driver
The tw6869 driver requires a different physical address to allow
DMA'able buffers for decreasing latency between chip and display
* v4l2src: add fractional "fps" property
(obsoletes the "fps-n" property)
* Add GstImxV4l2Meta init function
This avoids the g_assert() that was caused by the missing init
function
* Add num-additional-buffers property
This can be useful if capturing video isn't smooth; it sets the
number of internal additional buffers, so if downstream consumes
too many buffers, imxv4l2videosrc might end up doing a blocking
wait until buffers are returned
* imxv4l2src plugin is now called imxv4l2video, because it also
contains imxv4l2videosink
Also, the v4l2 elements can be enabled/disabled in the build
configuration individually now
* compositor:
* Only copy compositor input buffers to DMA memory once
If a single input frame is used for multiple output frames, we would
otherwise copy multiple times which can easily go to the limit of the
memory bandwidth
* vpu:
* Handle releasing of buffers without assigned framebuffer
This can happen if the buffer is released before it was actually
used, e.g. when renegotiating at the very beginning; prevents
a crash that would otherwise occur
* Add parameter check to avoid encoder crash on flush
* g2d:
* Add build configuration switches to explicitely specify G2D include
and library paths
* Disable cacheable memory allocation
Several issues were reported with cacheable DMA memory, so it is
turned off, at least for now
* blitter:
* Add property to clear screen to black in blitter sinks
* Add output-rotation property to videotransform base class
* audio:
* Fix reference counting for caps
* Mark static codec caps as may be leaked
This gets rid of the false positive in the leak tracer

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
