  • Android FFMPEG doesn't continue, throws no error

    8 octobre 2015, par Thommy

    I try to scale a video via FFMPEG in Android, but everytime I execute the command, it just stops producing console output.
    No Exception is thrown.
    The output looks like this. It just stops afterwards, the App is still running.

    /.../ffmpeg -i /.../VIDEO1.mp4 -filter:v scale=720:-1 -c:a copy /sdcard/test.mp4
    
WARNING: linker: .../ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

  • Android ffmpeg very slow to transcode

    23 mars 2016, par Nat

    In Android phones (different phone models) it takes ffmpeg 5x the length of the video to transcode. A 1-minute video takes near 5 minutes to transcode. I have tried the following to improve performance and nothing has helped,

    -b:v 16K to 1024K
    
-s 180x120 to 1920x1080
    
-preset ultrafast
    
-profile:v baseline
    
-r 24 to 100
    
maxrate 64K to 512K
    
rate 64K to 512K
    
-threads 0 to 16

    Nothing seems to help. Of course, some of them bring the speed up to 3x from 5x.

    Please help as I have run out of options.

    My current code is,

    ffmpeg -y -i /storage/emulated/0/DCIM/Camera/VID_20150819_220414.mp4 -strict experimental -s 480x270 -vcodec libx264 -r 24 -c:a copy /storage/emulated/0/Android/data/<myapp>/cache/VID_-K-qMCldTSzZomKakNzq.mp4
