  • FFMPEG encoding is rotating portrait images uploaded from the iPhone

    27 juillet 2017, par Kevin J

    I’m trying to figure out why FFMPEG is rotating my thumbnail image when a portrait video is uploaded from an iphone.

    Here is my command line test :

    ffmpeg -i video/test.mp4 -c:v libx264 -profile:v high -level 5 -crf 18 -preset medium -maxrate 10M -bufsize 16M -pix_fmt yuv420p -vf "scale=iw*sar:ih, scale=\'if(gt(iw,ih),min(1920,iw),-1)\':\'if(gt(iw,ih),-1,min(1080,ih))\'" -x264opts bframes=3:cabac=1 -movflags faststart -b:a 320k -y video/test.mp4 -vcodec mjpeg -vframes 1 -an -f rawvideo -s 410x231 video/testthumb.jpg 2>&1

    Then the portrait image is rotated 90 degrees to be made a landscape image, but the video stays portrait. How can I keep the orientation the same ?

  • Why are Iphone videos upside down ?

    7 juillet 2017, par hendry

    I have a video file captured using the standard Camera app copied off my Iphone5 using btsync :

    orig.mov: ISO Media, Apple QuickTime movie

    That plays upside down in mplayer or vlc.

    When I transcode it using AWS’s elastictranscoder using a standard preset :

    elastictranscoder.mpg: ISO Media, MPEG v4 system, version 1

    That transcoded video file plays back the right way up.

    When transcoding myself, using ffmpeg I need to explicitly rotate the video otherwise the resulting mp4,webm files are upside down.

    So I am guessing AWS’s elastictranscoder auto rotates the video somehow. However why is the video upside down to begin with ?
