Play HEVC/H.265 Videos and Embed HEVC Streams into MP4 and TS Files with openHEVC and GPAC

I wrote an introduction to H.265 (aka HEVC) at the end of last year, including instructions showing how to encode videos to HEVC using the reference implementation. It worked but since it was not optimized for speed, it was extremely slow. Today I’ve stumbled across openHEVC, a open source compliant HEVC video decoder written in C, created as a fork of Libav. This is supposed to work pretty well as the implementation was used at Roland Garros Tennis tournament to playback an 720p50 HEVC stream transmitted over DVB-T2, IPTV, and MPEG DASH. Today I’ll mainly tried out the instructions provided on openHEVC github repo including: Build the source and playing a raw HEVC stream with hevc utility Build GPAC (open source multimedia framework), to get MP4Box, mp42ts, and MP4Client utilities. Import a raw HEVC stream into MP4 and TS containers, and play it back with GPAC tools. I’ve performed the […]

Zyxel NSA310 / NSA320 Hackable Network Access Storages Run Debian Linux

Yesterday, we saw how to make a NAS enclosure for the Cubieboard, but DesertF0x commented “Better take a NSA-310 or NSA-320. It is easy to install Debian and it has Gigabit!”, and I decided to have a look. The 2 devices appear to have been released at the end of 2011, and are powered by a Marvell ARMv5 compatible processor. Many NAS are expensive kits, but NSA310 (1 bay) is currently available for $88.50 and NSA320 (2 bays) for $95.34 on Amazon, which is just a little cheaper than the DIY Cubieboard NAS solution (~100 USD). Price looks attractive, now let’s have a look at some technical details, and instructions to install Debian. Both NAS more or less share the same hardware specifications except for a few details: Processor – Marvell Kirkwood 88f6281 ARMV5-TE compliant processor @ 1.2 GHz (Hardware datasheet) System Memory – 256 MB (NAS310) or 512 MB […]

Linaro Connect Europe 2013 Sessions and Mini-Summit

Linaro Connect Europe 2013 (LCE13) is taking place in Dublin, Ireland on July 8 – 12, 2013. If you are not there, you can still follow the event remotely as the event schedule is available with tracks focused on Android, Builds and Baselines, Enterprise, Graphics and Multimedia, Linux Kernel, Network, Project Management Tools and Training, and the Testing and Validation mini-summit will also take place at the same time. There will be hacking and lab sessions each day (except on Friday) where you can expect to learn useful skills. I’ve selected 2 sessions per day that I think might be particularly interesting. Monday 10:00 – 10:45 – ARMv8 Status and Updates Current Status of v8 tree What’s merged? What’s features are next priorities? Platform Updates What members should know about adding new v8 platforms 12:00 – 13:00 – How to make Android more efficient for entry level products The main objective of […]

Cloud Media FreeOTT Player Review

Syabas was a company designing set-top boxes such as Popcorn Hour Media Tank that were relatively popular before the Android media player invasion. The company is now called Cloud Media, and they offer a tiny media player called FreeOTT that connects to their Apps Market and bring online video, Internet radio, social media and other streaming media to your television. The device is free (as in free beer), as it’s not actually available for sale to the general public, and the only ways to get it is to have your ISP or telecom provider set it to you, or win one from the regular giveaways organized by the company. I won one via a giveaway announced on their Facebook page, and I had just to pay $5 (via Paypal) for shipping. The company does not provide detailed specifications for their device but we do know it’s a Linux based media […]

Tuxera FAT Embedded Boasts Faster and Better FAT32 Implementation for Embedded Linux and Android

Tuxera has announced their “FAT Embedded” implementation of the FAT file system specifically optimized for embedded Linux and Android. The company claims their commercial solution delivers much faster data transfers than competing FAT implementations. Beside providing better performance, it also includes features such as fail-safe operation, and lower power consumption. They’ve benchmarked different file systems including Tuxera FAT Embedded with different I/O buffer sizes on two embedded hardware: Marvell 6192 @ 800 MHz with 512 MB RAM and a 120 GB Corsair Force GT SSD (SATA 3) The write speed of Tuxera exFAT and FAT appears to clearly outperform even ext-4 in this particular system. As a side note, I also evaluated 2 embedded systems based on the same low-end CPU: one using NTFS-3G, and the other Tuxera NTFS back in 2010, and there’s was a massive performance difference at the time. NTFS-3G is a different beast as it uses […]

Lollybot is a $10 Robot Made with a USB Gamepad and Chupa Chups

I attended Barcamp Chiang Mai 6 yesterday, and sessions dealt with a wide range of subjects ranging from SEO and web development to things like nuclear energy, VMAT2 God gene, or Edward Snowden. There were just four talks somewhat related to the subjects I usually write about in this blog: Project Manhattan – An interactive TV infrastructure project for TV operators based on open source libraries (but not open source itself). They provide both back-end software and a mobile app (Android or iOS) for smartphones and set-top boxes. They had an Android set-top box, but unfortunately there was no time for demo. There’s no project website, but the solution is said to be used by horizon-tv.tv (in Russian). A Raspberry Pi session which I could not attend Firefox OS – Keng is the owner of a mobile and web development company called opendream, but he’s also one of the 4 […]

Linaro 13.06 Release With Linux Kernel 3.10 and Android 4.2.2

Linaro 13.06 has been released with Linux Kernel 3.10-rc6 and Android 4.2.2. Linux Linaro Stable (LSK) preview is based on kernel 3.9.6. There seems to have been a lot of activity for the LAVA and Builds and Integration teams, with LAVA support for new SoC such as Huawei K3V2 and Broadcom Capri from 2 companies which have recently joined Linaro as members, and well as continuous build for Linaro Stable Kernel. On the kernel side, more work has been done for multi-platform support (unified kernel), uprobes, eMMC power mamangement, and more. Here are the highlights of this release: LAVA LAVA Core As part of the effort to improve the developer experience with LAVA, the different client tools were consolidated into a single package, which simplifies the process of updating the tools and makes it easier for the team to provide new features for LAVA users. LAVA now supports KVM devices, […]

Qualcomm Snapdragon 800 MDP Benchmarks

A few days ago, I saw some benchmark results showing Xiaomi M3 smartphone powered by Snapdragon 800 SoC getting a ridiculous score above 80,000 points in Antutu, but thought it was really odd, and it turned out to be a fake Antutu screenshot. The actual scores for Snapdragon 800, are much lower, yet one of the fastest mobile platform ever, according to benchmarks performed by Engadget, which hold of Qualcomm Snapdragon 800 Tablet and Smartphone MDPs. Engadget provided comparison of the benchmark for 12 devices, but I selected the 4 most powerful of the lot in the table below. S800 MDP tablet (MSM8974) S800 MDP phone (MSM8974) Samsung Galaxy S4 (Exynos 5 Octa) Nvidia Tegra 4 ref device Quadrant 2.0 20762 22022 13326 16436 Vellamo 2.0 2997 2914 1977 N/A AnTuTu 3.x 35783 33828 28167 36305 SunSpider 0.9.1 (ms) 543 566 732 499 SunSpider 1.0 (ms) 657 674 N/A N/A […]
