Tegra x1 – ridgerun developer connection


This wiki contains useful information about Tegra X1’s world (Jetson TX1), the new Nvidia’s platform. Gbp to usd converter It also contains some details on the differences between it and its main competitor the SnapDragon.

RidgeRun is working with the SnapDragon 805 which can do 4K H265 decoding from Inforce, this as an R&D project, the board that we have is the 6501 from Inforce and we verified that it can do H265 decoding and encode 4K resolution on H264 at 30fps, we even created an SDK for the board, however we found several problems on the design that Qualcomm used for the SW and the support available:

a) In the capture side they use something called mm-qcamera-daemom to handle the capture because the IOCTL related to capture are implemented in user space by this demo which is called by the kernel (ugly and cause overhead). The binary system The worst part is that the daemon is linked with bionic and not libc so the daemon which is not open source just the binary cannot run on a system without android.

c) You don’t have access to the individual components that would accelerate the frames processing, i.e, you say start recording and it would do it for you without having access to the buffer on any part of the processing chain.

f) People from LInaro is working on an older snapdragon so the support for the 810 is very limited. Pound to euro forecast 2016 Right now it seems that only android is well support but with a poor performance on tasks involving the camera – too much arm consumption, like 30%.

The one that supports H265 encoding is the 820, not sure if there is a EVM for it. Pound vs dollar exchange rate history We were able to port the BSP to the SDK and have the board booting, RidgeRun got the SDK working with wireless and display. Euro price today in pakistan But the capture subsystem was dead because the daemon cannot run outside of Android.

c) There is a lot of documentation for the board. Inr to usd exchange rate today It includes a good level of details, including schematics, BOM, TRM, datasheets. Binary to octal You can check it on the developers site of Nvidia:

d) There is an Linux SDK for the board provided by NVIDIA, it includes the BSP and several development tools, it is called JetPack and the Linux package is called Linux4Tegra (L4T) , the latest version available is R23.2:

e) JetPack also supports gstreamer 0.10 and gstreamer 1.0 but the H265 support is only available on gstreamer 1.0. Usd to inr conversion rate today There is good documentation about how to use the pipelines, you can find this documentation on the multimedia pdf. Fx rate gbp usd It support H265, VP8, H264 etc. Decoding activities You can find information about resolutions and framerates on the datasheet as well
