video-recording

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.

I am trying to record video using AVFoundation.

I have come across 2 plugins with ability to capture/save an image as a file with flutter: Camera v0.0.2 and Image_picker v0.2.1 , they work well and are official flutter plugins. In essence I would like to build a mini camera plugin with video recording capabilities with flutter, which would work with iOS and Android seamlessly.

When I record video by MediaRecorder, it always records in landscape mode, regardless of real device orientation. How to force MediaRecorder/Camera use real orientation ? refer to Camera.Parameters.setRotation() for more information. There is an example there and instead of calling setRotation(rotation) try to call mediaRecorder.setOrientationHint(rotation) when recording video. Sagar Aghara Add the following two lines of code: Camera.setDisplayOrientation(90); // use for set the orientation of the preview mRecorder.setOrientationHint(90); // use for set the orientation of output video before:

What is the best way to record a video with augmented reality? (adding text, images logo to frames from iPhone/iPad camera) Previously I was trying to figure out how to draw into CIImage ( How to draw text into CIImage? ) and convert CIImage back to CMSampleBuffer ( CIImage back to CMSampleBuffer ) I almost did everything, only have problem with recording video using new CMSampleBuffer in AVAssetWriterInput But this solution anyway isn't good at all, it eats a lot of CPU while converting CIImage to CVPixelBuffer ( ciContext.render(ciImage!, to: aBuffer) ) So I want to stop here and find some
