问题 Is it possible to get frames while recording a video and writing current time on those images at the same? I've been looking for this but I couldn't find anything.

问题 In my company, i had the task to build a website, where users can record a video, that will be send to the server, some stuff will be done and the user finally gets an email with a link to a microsite with that video embedded. After some research, i came to the conclusion, that it is impossible, at least at the moment, to capture a video with getUserMedia on iPad. So the solution is quite simple, i just use a input-element with accept="video/*;capture=camcorder". <input type="file" accept=

问题 I'm using FFmpeg version 3.3.4 (installed via brew) through the command line to record my desktop during some automated tests on my macOS Sierra (10.12.6). I would like to record only a specific section of the screen but, unfortunately, I'm not able to find the proper options in the documentation to reach my goal.
