libyami 0.1.4 release
=====================

features update
---------------
    -   Additional fixes(most are thread race condition) for v4l2 wrapper (egl/gles)
    -   Add glx support in v4l2 wrapper
    -   Basic transcoding support: encoder test accepts input data from decoder output
    -   Testscript is added, it supports one-run-for-all: with a folder including h264/vp8/jpeg/raw-ref,
        we can test them in one run. It serves as BAT (basic acceptance test) for pull request merge.
    -   Report fps in decode test, support decoding only test (skip rendering)
    -   Vp8/jpeg are supported in v4l2 decoder as well
    -   Decode test can be built/run without X11
    -   Code refinement for decoder test output and encoder classes
    -   dma_buf fixes, when video frame is exported as dma_buf, it renders well as texture
    -   with additional patch for chrome:
        V4L2VDA/V4L2VEA pass chrome video unit test
        video playback in browser draft ok
