  • How to convert a 16:9 video to 4:3 video with top & bottom blurred video bars by using ffmpeg ?

    27 décembre 2018, par Wai Gyi

    I would like to convert a landscape video to a square video with blur bars at top and bottom.

    I tried to adapt the commands from the following link but not succeeded.

    FFmpeg : How to convert horizontal video 16:9 to vertical video 9:16, with blurred background on top and bottom sides

    So, can someone share a ffmpeg command with me ?

    Thank you very much for your help.

    Update : I tried again and get a working command. Please check and review.

        ffmpeg -i in.mp4 -lavfi "[0:v]scale=iw:iw*3/4,boxblur=luma_radius=min(h\,w)/40:luma_power=3:chroma_radius=min(cw\,ch)/40:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,setsar=1,crop=h=iw*3/4" out.mp4

  • FFmpeg - Add Audio to Video - Audio cuts out

    13 mars 2021, par John Doe

    I have a problem with my Batch-file FFmpeg command. I wish to concat 3 videos into one, and add background music starting after 10 seconds.

    


    The video renders properly, however the music cuts out 10 seconds into the second concat video and the rest of the video is silent.

    


    (echo file 'loading.mp4' & echo file 'slide.mp4' & echo file 'outro.mp4') | ffmpeg -y -init_hw_device qsv=hw -filter_hw_device hw -hide_banner -protocol_whitelist file,pipe -f concat -safe 0 -i pipe: -stream_loop -1 -i "music.mp3" -filter_complex "[1:a]adelay=10000|10000,afade=t=in:st=11:d=10,volume=0.2[a1];[0:a][a1]amix=duration=first[audio]" -map "0:v" -map "[audio]" -c:v h264_qsv -c:a aac -vb 10M -preset veryfast -r 30 "done.mp4"


    


    Any ideas ?

    


  • Do we need to transcode mp4 or mp3 to HLS format for streaming video/ audio on mobile app ?

    5 mai 2016, par ken_vk

    We are developing a mobile app which play music and video .

    The music (.mp3) and video(.mp4) is about 5 - 20 MB . I knew we must to transcode from .mp4 to HLS format ( .m3u8) for streaming. And I still consider about transcode audio file to HLS format whether or not ?

    I have two question.

    1. Do we need transcode video (.mp4) to HLS format if the files are about 5- 20 MB.

    2. Do we need transcode mp3 file to HLS format if the files are about 5 - 10 MB ?

    Thank you in advance,

    Regards,
    Khoa Nguyen
