  • Concatenating videos using concat demuxer in FFMPEG is finished but video is lost in second video?

    3 October 2019, by Gopinathan B

    Used concat demuxer in FFMPEG code to concat videos :-

    cmd = arrayOf("-y", "-f", "concat", "-safe", "0", "-i", textFile!!.path, "-c:v", "libx264", "-crf", "23", "-preset", "ultrafast", "-c:a", "copy", outputFile.path)

    After concatenate finished, the video one played correctly has both audio & video but video two - video is missing has only audio. Output file has size & time duration including two videos.

    The textFile contains :-

    file '/path/to/file1'
    
file '/path/to/file2'

    Used absolutePath for two mp4 video files.

    Tryed this FFMPEG concat video finished but the video missing. But no solution to my problem.

    Anything I am missing in the command.

  • The most efficient way to generate mp4 video containing looped boomerang-alike video file?

    29 July 2019, by B. Palka

    I’ve developed an Android app that allows user to create boomerang-alike mp4 video. This video consists of 10 still images being played back and forth quite fast. I know that such video (boomerang effect) can be easily looped from single video file while playing it, but I really need to create a mp4 video that would essentially contain already prepared boomerang video. The output video can be downloaded and played by user on any external player (over which obviously I don’t have any control).

    For that purpose currently I create a video from images in a loop. The loop starts from 1st picture and goes to 10th picture with 0.25 sec delay between frames, then goes back from 10th to 1st including delay. And there is 5 of those loops, which essentialy means creating a single video from 5 * 10 * 2 = 100 images. I know it’s kinda ridiculous, so the time that it takes to prepare this video is riduculous as well (around 1:40 min).

    What solution could you recommend assuming that the output video really has to consist of 5 loops back-and-forth? I’ve thought about creating single loop video (20 pictures) and then create final output video by concatenating it 5 times. But could it be any good? I’m trying to find an efficient yet understandable for a beginner Android programmer way.
