  • How to stretch the WAV file to the same video length?

    5 October 2016, by Michael Heuberger

    So yeah, having a tricky ffmpeg issue here.

    In my app I’m encoding a video based on image frames and add a WAV file for the sound from the same source but through a different web socket. It can happen that the WAV file doesn’t always have exactly the same length as the video based on those images + fps (plus minus few seconds).

    How can I tell ffmpeg to "stretch" the input WAV file to have it the same length as the video?

    In short: images (i) + WAV (w) = final video (v)

    length(w) != length (v) ... which is causing problems.

    Here an example ffmpeg command I am currently using:

    ffmpeg -f image2 -thread_queue_size 512 -framerate 21.5 -i
    /frames/%d.webp -i videomail_preview.wav -y -acodec aac -strict
    experimental -ac 1 -vcodec libx264 -crf 16 -preset fast -profile:v
    baseline -pix_fmt yuv420p -loglevel warning -movflags +faststart
    videomail_good.mp4 -acodec libvorbis -ac 1 -vcodec libvpx -crf 8
    -deadline good -cpu-used 1 -pix_fmt yuv420p -loglevel warning -movflags +faststart videomail_good.webm

    Any suggestions/trick I am unaware of?

    avfilter/vf_alphamerge: warn if input not full range

    Alpha planes must always be full range, so complain loudly if fed
    
limited range grayscale input.
