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 Tested-by: Peter Seiderer <ps.report@gmx.net> Signed-off-by: Gary Bisson <gary.bisson@boundarydevices.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
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.
