Lentoid HEVC/H.265 Decoder(LentoidDec) is the world-leading HEVC/H.265 Decoder developed by Strongene Ltd, which is compatible with the reference software HM12.0. With multi-threading technology and adaptive single-instruction-multiple-data (SIMD) optimized algorithms, LentoidDec can acheive real-time decoding of up to 2160p videos on current existing PC. Moreover, LentoidDec is free for non-commercial use under the License Restrictions. More information can be found in Product Manual.

Compared with HM10.0, Decoding speed of LentoidDec improves greatly. Based on a 720p HEVC/H.265 stream encoded by HM10.0 and 1080p HEVC/H.265 stream encoded by LentoidEnc on PC configured with processor of i5-2400 and 4G RAM, some experimental results are as followings:

	1-thread	2-thread	4-thread
720p  download	174 fps	302 fps	461 fps
1080p  download	74 fps	131 fps	204 fps

LentoidDec can well support ultra-high resolution HEVC/H.265 video stream. Here a video stream with 3840x2160 resolution and 5.6 Mbps bit rate is provided for testing: scene.hm10
