  • "ffmpeg has text relocations" error in Android

    5 janvier 2015, par djzmo

    I’m building an Android video-sending application. I need the video to be compressed before being uploaded. In this case, I chose to use this Android wrapper of FFmpeg : https://github.com/hiteshsondhi88/ffmpeg-android-java

    FFmpeg error: WARNING: linker: /data/data/com.mycompany.myapplication/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

    Everything seemed fine when I compress small files (below 20 seconds), but when I tried to compress larger files, I seldom get the above error in the middle of the compression process, and the process was also terminated immediately. I need the application to be able to compress one minute video to about 20-35 MB.

    Here is the FFmpeg command I used :

    ffmpeg -y -i -codec:v libx264 -profile:v baseline -level 3.0 -b:v 2500k -minrate 2500k -maxrate 2500k -bufsize 1835k -pix_fmt yuv420p -preset ultrafast -crf 28 -codec:a copy

    Any idea on what went wrong ?
    Any kind of help would be very appreciated.

  • Adding date and time on a video using ffmpeg

    23 novembre 2015, par thewayman

    I am trying to add an date time stamp using ffmpeg.

    After some googling I have able to add timestamp via drawtext and timecode. Added an additional text for date.

    ffmpeg.exe -i input.avi -vf "drawtext=fontfile=arial.ttf:timecode='10\:20\:10\:00':rate=25:text='23-12-2015\ ':fontsize=20:fontcolor=white:x=0:y=50: box=1: boxcolor=0x00000000@1"  -f mp4 out.avi

    but the problem is when video starts from a day and end in the next day. i have no way to change the date.

    Please let me know a proper way to go about this problem. Thanks.
