From: Zhao, Halley Sent: Friday, October 24, 2014 3:51 PM To: [email protected]<mailto:[email protected]>; [email protected]<mailto:[email protected]> Subject: libyami 0.1 release Libyami is core video library to accelerate decoding/encoding based on libva. Libyami can be treated as development kit for VAAPI. It is developed by C++ language, with simple/efficient APIs, without external dependencies. libyami targets two type of usage: - Hardware accelerated codec is the major gap (there is existing media framework ), for example: Chromeos/Android, maybe ffmpeg. - Usage is simple enough that codec is the major interest, for example: remote desktop client/server, video surveillance. So far H.264 decode/encode, VP8 and JPEG decode are supported. VP8/JPEG encode support is under development. There are rich tests/examples in yami for a try. The tests can run without Window system (X11/Wayland etc), some modes of video output are supported: including raw data dump and some modes of texture (TFP, drm flink name, dma_buf). More details see: https://github.com/01org/libyami/wiki The future release plan are: Nov: v0.11: V4L2 VDA/VEA Dec: v0.2 Vp8 and jpeg encoder(depends on driver release) unified input/output buffer of yami Feb'15: v0.3 Vp9 decoder transcoding support with unified input/output buffer camera dma_buf support, camera with jpeg input use yami in ffmpeg for hw codec Future: h265 decoder legacy codec: mpeg2 decoder/encoder, vc1 decoder, mpeg4/h263 decoder/encoder Known issues: some jpeg file similarity <0.99 (~0.98) after decoding https://github.com/01org/libyami/issues/108 playback performance through gst-omx is not good: https://github.com/01org/libyami/issues/34 Encodeing quality through gst-omx is not good: https://github.com/01org/libyami/issues/36
