  • Find video resolution and video duration of remote mediafile

    22 février 2012, par osgx

    I want to write an program which can find some metainformation of mediafile. I'm interested in popular video formats, such as avi, mkv, mp4, mov (may be other popular too). I want basically to get :

    • Video size (720, 1080, 360 etc)
    • Total runtime of video (may be not very exact)
    • Number of audio streams
    • Name of video codec
    • Name of audio codec

    There is already the mediainfo, but in my program I want to get information about remote file, which may be accessed via ftp, http, samba ; or even torrent (there are some torrent solutions, which allows to read not-yet downloaded file).

    MediaInfo library have no support of samba (smb ://) and mkv format (for runtime).

    Also, I want to know, how much data should be downloaded to get this information. I want not to download full videofile because I have no enough disk space.

    Is this information in the first 1 or 10 or 100 KiloBytes of the file ? Is it at predictable offset if I know the container name and total file size ?

    PS : Platform is Linux, Language is C/C++

  • 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 ?
