We need a creative solution to burn captions into a video with the following style: If this project is a success, we may be able to use you for an ongoing need for similar scripting and/or sysadmin tasks. Style requirements: - Font: Open Sans - Size: 50 - Background: black with 75% opacity - The background box must "fit" the size of the text on each line, plus padding (ie. not extend far left or right of the text). - The background boxes for each line may not overlap Functional Requirements: - Inputs: - path to 1 video (mp4) - path to 1 caption / subtitle file (.srt, .ass, etc. - whatever you need, we can generate most common formats) - Outputs: - 1 video (mp4 with same resolution as input) - Must use readily available binaries in Ubuntu 16.04 - Must run from the command line with no GUI - Must make AT MOST one encoding pass - You may provide a shell script or PHP, Python or Node wrapper to simplify the command line interface. Note ffmpeg can get close, but we can't seem to get rid of the overlap as described here: I have some other ideas how to achieve this. In order of preference: 1. Maybe ffmpeg has some option to add proper line height or vertical line spacing to remove the overlap. This would be ideal, but based on my research I'm not finding an answer. 2. Parse the caption file and use drawbox and drawtext repeatedly (see answer on This may help, but I'm not sure how to keep the box at the proper dimensions relative to the text. 3. Use something like imagemagick to create PNGs containing the text and background box for each caption group, then use ffmpeg's overlay option repeatedly to add the images at the right time and position. This may provide the best control for sizing the background box, but is the most cumbersome. Other than that, I don't want to add too many constraints. We're just looking for a solution with a relatively clean interface that we can automate from the command line. Please bid if you are confident you can arrive at a solution meeting our requirements. Only bids that include a summary of your approach to solve this will be considered.

For our analytics tool we need a simple Kismet client. The client should be accessible through a REST API and listen on a specific port on Raspbian OS. If a request is sent to the client, it has to capture all surrounding WiFi network devices. Then the client fetches a list of MAC addresses we are looking for. It returns, which MAC addresses have been found via Kismet and if one or more of the MAC addresses from the list matches the predefined MAC address list. The client can be implemented using Python, C++, Java or Node.js. The timeline is short and the project can start immediately.

We are currently using OpenWRT on our routers and would like to present ads from time to time on the mobile and desktops that are using our free WiFi to help pay for the cost of the bandwidth. To do this we were thinking of using Ettercap or some other software to split the http and our ads into separate iFrames to keep the ad at the bottom instead of bothering them with this at the top of their screen...also to keep it persistent as they scroll around and use the top portion for their browsing. This way after a certain number of seconds...we could hide the ad as well so it's not pestering them for a long time....then show it later if they are still on for 10-15 minutes later or something.
