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>

This library provides an API for using the iMX6 VPU video
|
|
engine. It is an alternative to Freescale's VPU
|
|
wrapper. Both the wrapper and this library are layered on
|
|
top of imx-vpu, the low-level iMX6 VPU interface.
