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
- for v4l2 wrapper, see:
