At least one output file must be specified

    iam using windows 10, last version of ffmpeg, so what makes this problem. also how to make the style of the lyrics to be something like fade in/out and so on. if it’s possible
    Thanks in advance.
    update
    when i use this command

    ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest test1.mp4

    it give me this error

    Press [q] to stop, [?] for help

Conversion failed!

    i searched this error and i found a solution by add this part before output file so the final command is

    ffmpeg -loop 1 -y -i test.jpg -i test.mp3 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14'" -shortest -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" test1.mp4

    i got no error and it worked but the output video not contains any lyrics which i added

    Update

    last thing i tried and it works first i use this command to convert the image and mp3 file to a mp4 video

    ffmpeg -loop 1 -i test.jpg -i test.mp3 -shortest -acodec copy -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4

    but this command take a long time to process to convert mp3 of 2:55 minute it with image.
    then i start to add lyrics or subtitle using this command

    ffmpeg -i video.mp4 -vf "subtitles=test.srt:force_style='FontName=Arial,FontSize=14,PrimaryColour=&H0000ff&'" -c:a copy output.mp4

    this worked perfect and give the output but it take a long time to process i don’t know if this normal.
    now last thing how can i set the style of the subtitle so it be fade out or something

    This works very well in VLC, for example. However, Windows Media Player or Samsung TV does not play it. Windows Explorer does not even show a video thumbnail, so the video file is broken by Windows.

    Is not FFmpeg able to produce a standard MPEG4 file, or what the hell is this about ? I’ve tried all the alternatives presented, such as "-fflags +genpts", "-fflags genpts", "-movflags faststart", "-movflags +faststart", "pix_fmt=yuv420p" etc. but nothing worked.

    The sound I copied directly.

  • Ffmpeg : alternating audio languages in resulting movie for language learning

    20 novembre 2020, par almachuar
      

    1. Need to convert multiple-(audio)-language-video to single-audio-stream-video where 2 languages alternate repeatedly.
(10sec Lang2) + (15sec Lang3) + (10sec Lang2) + (15sec Lang3) + ... and so on till the end.
I assume it should be done with piping in and changing audio streams. (I've read ffmpeg piping documentation but didn't quite understand it).

      2. 


    


    I've done audio switching task (with scripting on Windows) by lively changing audio languages in video player but need better and crossplatform solution for little kid - preprepared video.

    


      

    1. If possible, to adjust loudness of one of the input audio streams to the other.

      2. 


    


    P.S. Think it would be useful for many married (programmers) to show little kids bilingual cartoons. (To prepare for language learning). By balancing 10/15 sec you may retain kid's attention — the older they grow the more native language they demand.

    


    Irrelevant, just for what's my experience :
