  • How to play video at exact seek time ?

    3 mai 2016, par RanceA

    I was working on a video player of an app and I ran into a problem.

    I need a video’s playing cycle locked into a specified time interval. For instance, I need a video loop to play from 00:04 to 00:08.

    My dilemma is, the video only has keyframes at 00:00 and 00:10, MediaPlayer.seekTo(4000) will seek the start time to 00:10 which is not what I expected. I need the video to play at a precise time, 00:04 to 00:08, not 00:00 to 00:10.

    FFPlay also supports AVSEEK_FLAG, but none of the flags seem to work in my case.

    Maybe playing at 00:00 then fast-forward encoding to 00:04 is a good idea, but I have no idea how to implement that. My FFMPEG experience is poor.

    Any help would be greatly appreciated.

  • Convert mp4 video with joining animation mp4 + audio(wav, mp3) using ffmpeg shell command

    24 mai 2021, par Dev-D

    I want to create .mp4 video by joining short animation(.mp4) + audio(wav, mp3) using ffmpeg shell command.

    


    I have tried few commands to join mp4 + audio here is my example command which will generate output video.

    


    ./ffmpeg -y -i ./output/preview-2.mp4 -i ./output/audio-file.mp3 -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -r 25 -vcodec libx264 -pix_fmt yuv420p ./output/converted-video.mp4

    


    But I want to play my animation till audio playing. The above FFMPEG command only join my animation(short video .mp4) file with audio and stopped animation playing after duration of short video reached to end (let's say animation file duration is 10seconds and stopped playing after 10 seconds). But my audio is about 3 minutes and I want to re-play the animation video again and again till the audio file duration (3 minutes). Just like a looping effect.

    


  • Need help to change working ffmpeg command to overlay instead of concatenate two audio files at specific position

    7 mars 2019, par lukistar

    By asking another question here, I got working code

    ffmpeg -i input.mp3 -i second.mp3 -filter_complex "[0:a]atrim=end=10,asetpts=N/SR/TB[begin];[0:a]atrim=start=10,asetpts=N/SR/TB[end];[begin][1:a][end]concat=n=3:v=0:a=1[a]" -map "[a]" output

    The code inserts second.mp3 into the input.mp3 at 10 seconds.

    But now I need to overlay second.mp3 into the input.mp3 starting at 10seconds.
    In other words I need playing input.mp3 and after 10 seconds I need start playing second.mp3 simultaneously.

    The code I have been given keeps the params of input.mp3 and changes everything about second.mp3 to match input.mp3.

    Could you help me altering the command I have to do the overlay...
