  • Combining video and audio from multiple sources using ffmpeg

    11 juillet 2015, par Raheel Khan

    I am trying to add an audio file to a video file using ffmpeg.

    ffmpeg.exe -i "Video.avi" -i "Wave.wav" -map 0:0 -map 1:0 -vcodec copy -acodec copy "Output.mp4"

    The above parameters work but the output file length is the greater of the two input lengths. How can I specify using the video’s length instead ?

  • ffmpeg add long text in multiline automatically

    30 juillet 2016, par Pranoy C

    I am using ffmpeg to add text to a video. Currently this command works for me :

    ffmpeg -y -i cut.mp4 -vf drawtext="fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: text='Stack Overflow': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)/2: y=main_h-(text_h*3)" -codec:a copy output.mp4
    1. If I have a very long text "Stack Overflow is awesome and this is a test of long text", is there a way to automatically make it wrap without me having to insert new line characters in the text ?

    Currently such a text just goes off the screen if I don’t have newline characters.

    1. Is there a way to specify maximum width & height for the text ?

  • Combining 2 FFMPEG Commands

    11 juillet 2020, par John Doe

    I'm trying to combine 2 ffmpeg commands, one which creates the video, and another which adds a simple fade to the beginning of the created video. Here's what I have :

    


    ffmpeg -y -stream_loop -1 -i "video.mp4" -stream_loop -1 -i "music.mp3" -i "audio.mp3" -filter_complex "[1:a]volume=0.1[a1];[2:a]adelay=5000|5000,apad=pad_dur=10[a2];[a1][a2]amerge=inputs=2,afade=in:st=0:d=5[audio]" -map "0:v" -map "[audio]" -c:v libx264 -c:a aac -ac 2 -ar 22050 -preset veryfast -shortest "output.mp4"

ffmpeg -y -i "output.mp4" -filter_complex "[0:v]fade=in:0:d=5" -c:a copy -preset veryfast -movflags faststart -fflags genpts "done.mp4"


    


    The two commands work perfectly fine, however the second one takes about the same amount of time to process as the first, and I feel it should be relatively easy to do the fade-in during the first encode. For my skillset atleast, I was wrong. Please could someone with more experience lend a helping hand ?

    


    Thanks.
