The Best HEVC/H.265 Decoder

compatible with the reference software HM12.0

4Kx2K Real-time Decoding

Decoding speed improved greatly by multi-threading technology and adaptive single-instruction-multiple-data (SIMD) optimized algorithms

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-thread2-thread4-thread
720p  download174 fps302 fps461 fps
1080p  download74 fps131 fps204 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
In order to give a more comprehensive evaluation of the superior performance of LentoidDec,we carry out a group of systematical decoding speed comparison experimtents over i7-2600 CPU,8GB memory and Windows 7 operating system, where the decoding speed of LentoidDec are compared with that of FFmpeg HEVC decoder (click to download), Elecard HEVC decoder plugIn (click to dowload) and the reference software HM10.0 decoder in decoding various standard test sequences. The test reports can be downloaded here (note that this test report is just experimental results without any specific purpose).
