  • 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

    Here the error log :

  • FFMPEG command works on Mac but not on Windows [duplicate]

    24 décembre 2019, par Arthur

    This question is an exact duplicate of :

    Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :

    ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4

    charts are located in the same folder with name as img-0001.png img-2000.png

    It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.

  • ffmpeg and php does not end the conversion

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