H.265 promises the same video quality as H.264 when using half the bitrate, so you may have thought about converting your H.264 videos to H.265/HEVC in order to reduce the space used by your videos. However, if you’ve ever tried to transcoding videos with tools such as HandBrake, you’ll know the process can be painfully slow, and a single movie may take several hours even with a machine with a power processor. However, there’s a better and fster solution thanks to hardware accelerated encoding available in some Intel and Nvidia graphics cards. For this purpose, GearBest sent me Maxsun MS-GTX960 graphics card, a second generation Maxwell GPU, that supports H.265 accelerated video encoding and promised up to 500 fps video encoding. So I’ve put the graphics card to the test in a computer running Ubuntu 14.04, and reports some of my findings here. Similar instructions can also be followed in […]
H.264 & H.265 4K Video Playback on Amlogic S905 Android TV Box
I’ve almost completed my review of Videostrong K1 Plus Android box powered by Amlogic S905, and while there are many shortcomings, 4K video playback is actually pretty good with Android’s Video Player (Kodi is not really usable @ 4K). I connected the device to LG 42UB820T 4K UHD TV, and set video output to 2160p @ 60Hz, and went through several video samples: Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265 @ 30 fps – No audio) – OK big_buck_bunny_4k_H264_30fps.mp4 (H.264 @ 30 fps – MPEG1/2 and AC3 audio) – OK big_buck_bunny_4k_H264_60fps.mp4 (H.264 @ 60 fps – MPEG1/2 and AC3 audio) – Video looks somewhat OK, but big audio delay or AV sync issue. BT.2020.20140602.ts (H.265 Rec.2020 compliant – AAC audio) – OK (First time I can play this video on any hardware). Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (H.265 @ 60 fps – AC3) – Video is very good, but no audio MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC @ 24 fps – no […]
MPEG2 and VC-1 Codecs, H.264 Encode and HDMI CEC Are Now Available for the Raspberry Pi
Many people appear to have bought the Raspberry Pi in order to use it as a cheap media player by installing distributions such as Raspbmc or OpenElec. The only problem is that this low cost board was primarily designed as an educational platform, so the Raspberry Pi foundation only paid for H.264 licensing, which means you could only playback H.264 videos, and all other video codecs could not be played (by hardware) making it a rather poor media player. But things have improved, as the good people at the Raspberry Pi foundation have worked out a deal with the licensing organizations and now offer support for 2 new codecs: MPEG2 license key – 2.4 GBP (~3.8 USD) VC-1 license key – 1.2 GBP (~1.9 USD) Once those 2 codecs are enabled you should be able to play your DVD rips and most HD wmv files smoothly. The way it work […]
Ziilabs ZMS-40 Decodes 6 HD Videos and Maps them to 3D Objects Simultaneously!
Ziilabs uploaded an impressive video that shows the Ziilabs ZMS-40 simultaneously decoding 6 High Definition Videos (although they don’t say if it’s 720p or 1080p) with 5 H.264 videos and 1 VP8/WebM video and rendering them on 3D objects via OpenGL ES. That’s quite amazing, but the next question could be why would you need that much processing power in a chip aimed at tablets? Augmented reality perhaps… Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com
