  • ffmpeg vcodec copy does not work when start/duration is messed up in video file

    24 septembre 2019, par anishsane

    My Video file shows below meta-data with ffprobe/ffmpeg:

    Duration: 00:44:27.52, start: 1333.760000, bitrate: 335 kb/s
  Stream #0.0(und): Video: h264 (Main), yuv420p, 640x480, 25 tbr, 90k tbn, 50 tbc

    Note: The file does not contain audio.

    I am trying to convert this video file to other video file, using ffmpeg/avconv.

    This works: (but encodes h.264 video to mpeg4)

    ffmpeg -i input.mp4 output.mp4

    & it generates output file of proper duration (44:27 - 1333 seconds = 22:14)

    This does not work:

    ffmpeg -i input.mp4 -vcodec copy output.mp4

    Generates file without video.

    The output contains:

    $ avconv -i input.mp4 -vcodec copy output.mp4

  • create single video form 3 separate videos using FFmpeg

    24 septembre 2019, par Shijin

    I was trying to create single video form 3 separate videos using FFmpeg.

    ffmpeg -y -loglevel debug  -i /home/ubuntu/test/1569317318/15693173181124138568.webm   -i /home/ubuntu/test/1569317318/1569317318867082351.webm   -i /home/ubuntu/test/1569317318/1569317318191333163.webm  -filter_complex '[0]scale=320:-1[a];[1]scale=320:-1[b];[2]scale=320:-1[c];[3]scale=320:-1[d];[a]pad=640:480[x];[x][b]overlay=320[y];[y][c]overlay=0:240[z];[z][d]overlay=320:240;[0][1]amix'  -c:v libx264   -crf 23   -preset veryfast   -shortest   /home/ubuntu/test/1569317318/1569317318478598265.mp4

    This is not woking, It throws an error like bellow

    Invalid file index 3 in filtergraph description [0]scale=320:-1[a];[1]scale=320:-1[b];[2]scale=320:-1[c];[3]scale=320:-1[d];[a]pad=640:480[x];[x][b]overlay=320[y];[y][c]overlay=0:240[z];[z][d]overlay=320:240;[0][1]amix.

    How to fix it? If we provide four inputs, It is working

  • How to increase encoding speed of ffmpeg in adding text/sticker to video ?

    24 septembre 2019, par Gopinathan B

    While adding text/sticker to video using FFMPEG library in android. Processing time is very slow.

    For adding text to video I am using following command -

    cmd = arrayOf("-y", "-i", videoFile!!.path, "-vf", "drawtext=fontfile=" + font!!.path + ": text=" + text + ": fontcolor=" + color + ": fontsize=" + size + border + ": " + position, "-c:v", "libx264", "-preset", "ultrafast", "-c:a", "copy", "-movflags", "+faststart", outputFile.path)

    For adding sticker to video I am using following command -

    cmd = arrayOf("-y", "-i", videoFile!!.path, "-i", imagePath!!, "-filter_complex", position!!, "-preset", "ultrafast", "-codec:a", "copy", outputFile.path)

    While merging two video files also takes more time -

    cmd = if (havingAudio) {
   arrayOf("-y", "-i", videoFile!!.path, "-filter_complex", ffmpegFS!!, "-map", "[v]", "-map", "[a]", "-preset", "ultrafast", outputFile.path)
} else {
   arrayOf("-y", "-i", videoFile!!.path, "-filter:v", ffmpegFS!!, "-preset", "ultrafast", outputFile.path) 
}

    I have tried FFmpeg adding image watermark to video process is very slow. But processing time is not increased.

    Help me how to make processing time faster in FFMPEG.

  • ffmpeg : how to extract multiple clips from a movie at once

    24 septembre 2019, par Ginso

    Now I can extract a clip from a movie using

    ffmpeg -i movie.mp4 -ss 01:05:10 -t 00:01:30

    now, I want to extract a few clips from one movie and especially those late in the movie take very long. I guess ffmpeg has to decode the whole movie up to that clip. Is there a way to extract all clips with one command, so that ffmpeg has to go through the movie only once? The clips don't overlap
