  • ffmpeg and php does not end the conversion

    23 juin 2016, par Fernand Royale

    I’m going crazy with it and do not think the solution.

    I use this code to convert videos, but the conversion did not terminate. I tried several times and stops at different points.

    echo "Starting ffmpeg...\n\n".'';
    echo shell_exec('/usr/src/ffmpeg/ffmpeg/ffmpeg -y -i movie.mp4 -i logo.png -filter_complex "overlay=10:10" -b:v 1500k -vcodec libx264 movie2.mp4 2> out.txt').'';  
    echo "Done.\n";

    Output from ffmpeg :

  • ffmpeg Conversion issue with 3:2 aspect ratio

    5 mai 2015, par nurma

    Sometimes there is an issue when i try to convert to mp4 using ffmpeg. I’m getting issue "Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height". Maybe, this is because of input video file, that has dimensions 720x480 with aspect ratio 3:2. Please help me, how to correctly convert this type of video.
    This is the command :

    ffmpeg -y -i input.mp4 -i watermark.png -filter_complex 'scale=-2:360,overlay=(main_w-overlay_w)-20:(main_h-overlay_h)-20' -codec:v libx264 -profile:v main -preset slow -b:v 300k -maxrate 300k -bufsize 600k -threads 0 -codec:a aac -strict experimental -b:a 128k -crf 20 output.mp4 1> output.log 2>&1

  • ffmpeg created timelapse won't play on other players than VLC

    27 février 2019, par theFeiter

    I am creating a Timelapse Video with the following ffmpeg command :

    ffmpeg -r 24 -start_number 7754 -i IMG_%d.JPG -pix_fmt yuv420p -s 1920x1080 Output.mp4

    This works without errors, but when I try to play the .mp4 on my Android Phone it shows an Error : "Unable to play file. Not enough resources"

    With the VLC App : "Currently unable to play this video. Stop the other video and try again"

    When I put the Video through Handbrake It plays fine on all players.

    I tried out changing some ffmpeg options, but nothing helped.

    When I compare the output of ffmpeg -i Output.mp4 from the original with the output from the video out of handbrake it differs only in the video bitrate.

    Are there any other options I can try to change ?

    This is the ffmpeg output :
