  • ffmpeg terminal : How can I re-encode a video file using all the parameters copied from another video ? [closed]

    5 décembre 2022, par Lever

    I have two videos A and B. How can I re-encode B using ALL the parameters of A ?
I would like to use both A and B as inputs, but all parameters are extracted from A, then B is re-encoded with the A-parameters including both video and audio. Is there a simple command to copy ALL the parameters of A ?

    


    Thanks !

    


    I know the typical parameters of a video includes the resolution, fps and so on. But it seems that I always miss something rather than get ALL the parameters to make A and B the same.

    


    The background is that I need to concatenate about 100 videos, but only a few of which has lower quality than others. I don't want to re-encode all of them. Therefore I'm trying to re-encode the lower ones to match the others, and then I can use the file-level concatenation command avoiding re-encode all of them.

    


  • ffmpeg merge silent video with another video+audio

    4 mars 2016, par Mark Dagger

    I want to create, in a single command, a video from 3 sources :

    1. a silent background video ;
    2. a smaller video to be overlayed (same length of 1), KEEPING its AUDIO ;
    3. a PNG logo to be overlayed

    I can create the video but cannot get the audio track. I don’t understand if -vf is supposed to work in this case. This is what I’ve tried to do :

    ffmpeg.exe -y -i MASTER_SILENT_VIDEO.mp4 -vf "movie=SMALLER_VIDEO_WITH_AUDIO.flv, scale=320:-1[inner];movie=MY_LOGO.png[inner2]; [in][inner] overlay=800:480,amerge [step1]; [step1][inner2] overlay=30:30 [out]" completed.mp4

    The "amerge" filter should do the audio merging job, but of course it doesn’t work. I’ve found similar questions involving -map or filtergraph but they refer to mixing a video source and an audio source ; I tried several filtergraph examples without success. Any idea ?

  • Convert video from FFMPEG than video is rotated [duplicate]

    25 octobre 2016, par user7050166

    This question already has an answer here :

    I have created one Application API, in this Application API When i have upload video from file manager than video is rotated but when i have capture and direct upload than video is perfect work.

    i have use this command transpose=1 but capture video is rotated 90 degree when upload and if i have remove this command than file manager video is rotated.

    so please give me solutions.

    /usr/bin/ffmpeg -i video.mp4 -i watermark.png -filter_complex 'overlay=10:10' -s 640x1280 -b 512k -vcodec mpeg1video -acodec copy -vcodec h264 -acodec aac -strict -2 output_video.mp4

    file manager upload video is auto rotated on 270 degree, i have not use any rotated command but capture video is work perfect.
