  • Trim video in Android using ffmpeg, audio and video not in sync

    8 novembre 2017, par Nidhin Radh

    I’m creating an Android application which process video files and I’ve used VideoKit library (https://github.com/inFullMobile/videokit-ffmpeg-android) to integrate ffmpeg with the application.
    I used the following snippet to trim a video,

                        Command command= videoKit.createCommand()
    
                                    .overwriteOutput()
    
                                    .inputPath(ipfile.getAbsolutePath())
    
                                    .outputPath(opfile.getAbsolutePath())
    
                                    .customCommand("-ss 10 -t 30 -vcodec "+ 
    
                                     "copy -acodec copy -async 1")
    
                                    .copyVideoCodec()
    
                                    .experimentalFlag()
    
                                    .build();
    
                            command.execute();

    Sometimes the output seems to be okay, but sometimes the video and audio are not in sync, i.e. video ends before audio. Most of the time this happens with videos downloaded from YouTube.
    Can someone give me an idea to trim videos in android without any problems ?

  • How to create video with dynamic pictures like Facebook Friend's Day video

    21 février 2019, par Vinicius

    How to create a video with pictures from a user just like Facebook does with their Facebook Friend’s day video ?

    Example : https://www.youtube.com/watch?v=mNWJ_XxfQfU

    The intention is to generate this sort of video with images that a visitor will upload to a website. FFMPEG does support images animation but it seems that a bit of 3d animations like the above needs ages to be done with FFMPEG. I wonder if there is an alternative to FFMPEG that can generate this sort of animations, or maybe a software like After Effects that can either generate a template that can be used on ffmpeg (or any command line alternative) or has its own command-line interface that can be executed in a linux machine to do such thing.

    Basically, the user would upload the pictures, the server would crop them to have the same size and then it would convert it to a video like the one mentioned above.
