  • how to make this ffmpeg concat better or fast ?

    21 mai 2021, par JohnTerry

    I am using this command to concat video urls and producing output video as .webm but it is very slow how do i make this faster ?

    


    command is -

    


        cmd = "ffmpeg -safe 0 -f concat -protocol_whitelist file,http,https,tcp,tls,crypto -segment_time_metadata 1 -i {} -vf select=concatdec_select,scale={}:{} -af aselect=concatdec_select,aresample=async=1 -c:v libvpx-vp9 -crf 30 -b:v 0 -b:a 128k -c:a libopus {}".format(text_file_path, width, height, output_video_path)


    


    I created a video of resolution 640:360 and full log for the video is posted below-

  • Use FFmpeg in Visual Studio

    12 février, par box

    I'm trying to use FFmpeg in a C++ project in Visual Studio 2010. I want to include the libraries as statically linked files. Simple programs like libavcodec/api-example.c compile without error and no linker error appears in the error view when starting them. However, a message box shows up after starting the application, saying that avutil-51.dll is missing. Do you have any hints on how to fix that ?

    



    I used the latest dev build from http://ffmpeg.zeranoe.com/builds/. Then I specified include as additional include directory, avcodec.lib ;avfilter.lib ;avformat.lib ;avutil.lib as additional dependencies and lib as additional library directory.

    


  • ffmpeg - Convert files but keep Same Date Modification as Original ?

    9 septembre 2021, par user5894146

    So I want to start with that ffmpeg and powershell isn't really my strength but I have been using the following powershell command to convert every .flac file in a certain directory to a 320K file.

    


    dir *.flac | foreach {ffmpeg -i $_.FullName -c:v copy  -b:a 320k  $_.FullName.Replace('flac', 'mp3')}


    


    This works exactly how I want to without any album art being transcoded but I want to incorporate a way so that the new .mp3 files that are created have the SAME DATE MODIFICATION value of the .flac files. Is something like this even possible ?

    


    audio_ex.flac = Date Modification: 1/1/2010
audio_ex.mp3 = Date Modification: 9/8/2021


    


    should be instead

    


    audio_ex.flac = Date Modification: 1/1/2010
audio_ex.mp3 = Date Modification: 1/1/2010


    


    I have a folder of 6K files and want each original date modified to match the newly created files so if I can do the above command and also have the date mod time match within one execution, that would be ideal.

    


    I thought of manually changing each files mod time using 3rd party tools but it will be too time consuming.
