  • ffmpeg : overlay video on top of a cropped video, map the overlay audio, cut the base video to the overlays length

    14 mars 2023, par roku

    I'm trying to overlay a video on top of a base video which is cropped to a shorts video format (standing phone). The overlayed video should be centered on top of the base layer. The base video's length should be reduced to the overlay's length. And I want to save only the overlay's audio.

    


    I've tried a bunch of stuff without much success. The current state of my ffmpeg command is this :

    


    ffmpeg -i overlay.mp4 -ss 00:00:00 -to <insert base="base"> -i base.mp4 -map 1:v:0 -map 1:a -vf "crop=ih*(9/16):ih" -crf 21 output.mp4&#xA;</insert>

    &#xA;

    But this only gives me the cropped version of the base video. So my questions are :

    &#xA;

      &#xA;
    1. How can I figure out the base video's length ?

      2. &#xA;

    2. How can I actually overlay (not map) other video on top of the base video ?

      3. &#xA;

    3. How can I map the overlay's audio ? Since -map 1:a the base's audio and -map 0:a says : "Stream map '0:a' matches no streams. To ignore this, add a trailing ' ?' to the map."

      4. &#xA;

    &#xA;

    Any help is appreciated.

  • ffmpeg - why I have three video streams in the output file when I have one video input (one video stream), one logo input

    17 juillet 2024, par Yazhou

    Hi I'm using ffmpeg to transcode some video files from prores or dv to h264/mov. Also I want to add a logo on it and make some other changes.&#xA;The command line I use is

    &#xA;

    ffmpeg -i input.mov -i logo.png -c:a aac -c:v libx264 -pix_fmt yuv420p -crf 18 -map 0:a? -map 0:v -filter_complex "yadif,[1]scale=iw*1:-1[wm];[0:v:0][wm]overlay=main_w-overlay_w-5:5" -disposition:v:0 default output_h264.mov

    &#xA;

    And what I got has three video streams. One for the logo,one for the video with logo, and one for original video.

    &#xA;

    Though I put the default video stream as the one with both video and logo as you can see for -disposition:v:0 default, and it's also playing that stream. But when I tried to upload it on Vimeo or Youtube, it uses the wrong stream.

    &#xA;

    &#xA;

    How can I change the command line to let ffmpeg only output one stream ?&#xA;And how can I remove the extra streams for the existed outcomes ?

    &#xA;
