We are looking for someone who knows how to program a raspberry pi. We have a few various functions we would like to achieve with the pi but we will start with one function and then progress from there. Our first task will be to upload and audio file, then have the audio file play back using a couple of different trigger events or methods. We can talk more about that when the time comes. Currently we are thinking Python would be the best language to use, but we are flexible. Must know the I/O of the pi well and be able to communicate to various ports.

We are looking for an embedded software developer to write the server side code of the Digi’s XBee. The server code is going to run on embedded Linux and should be written in Python and C++. The server side code should be able to run on RasberryPi (Debian), Beagleboard.org/black(Ubuntu/Debian), and/or Securifi Almond+(OpenWRT). The Securifi Almond+ router does not have Python installed on it. So, you would have to come up with a way to install Python. This is a starter project, and could definitely turn into regular work.

We are performing VPU accelerated video decoding and encoding using the Rockchip RK-3288 VPU drivers for linux written by Mac_L1 Link: https://github.com/mac-l1/machybris_examples We need to perform these transfers using device memory (GPU memory) instead of system memory (CPU memory) to gain higher frame rate performance. Android seem to contain code for performing these such as: A queue of VPU/GPU device memory buffers seems to be used at "https://github.com/mac-l1/machybris_examples/blob/master/snippets/firefly_android_4.4.2/RkOn2Decoder.cpp#L372". Also in Android you can look at "https://bitbucket.org/T-Firefly/firefly-rk3288/src/a3fb27a361885fd2f987a770a8555dd2a651bba1/frameworks/native/libs/gui/?at=master". For Linux there are several options for GPU-accelerated display, such as the Mali X11 driver discussed at "http://bbs.t-firefly.com/forum.php?mod=viewthread&tid=741&extra=page%3D1", or using Android's SurfaceFlinger code in Linux such as based on mac-l1's work. We need a solution for Linux (not Android) on our Firefly-RK3288 dev board. We need you to write C/C++ code for a pipeline that can decode H.264, render it to screen, and encode back to H.264 video frames in system memory, all running at 25-30 frames per second. It needs to be rendered into a window not full screen. A block diagram is attached showing what is needed.

Need change in ip camera firmware to point to new IP address of p2p server. We buy IP cameras from China. one of the companies we used to buy unfortunately closed and stopped servicing the p2p server based on a virtual server on Amazon web services. We recovered the server but the public ip is different, so we need to change the firmware of the ip cameras to point to the new ip address.

I'm looking for someone who has experience with Mikrotik Router. I want it to configure the following for a Hotel: - Load balancing between 3 internet connections (1 cablemodem 20Mbps, another cablemodem 20Mbps and 1 adsl connection 10Mb) so that makes the speed on wireless network as fast as possible. In wireless network the maximun number of devices connected between laptops, cellphone, tablets would be around 60. I would like to you can apply Qos for all connections. I have a mikrotik RB1100AHx2, would it be enough? would it better to have another mikrotik router for only load balancing? I've attached a picture of my network that I want to build As you can see It's not a difficult project unless you don't have the enough experience. Thank you so much for your attention
