  • lavfi/deshake : fix deshake crash issue.

    lavfi/deshake : fix deshake crash issue.

    Fixes ticket #7441.
    

    for block contrast calculate, the block is like this :
    

    


    
<---------------- stride-----------------------
    
    

    

    +----------------------------------------------->  X
    
|
    
|            w = 16
    
|    (cx,cy)+------+
    
|           |      |
    
|h=blocksize|      |
    
|           |      |
    
|           +------+
    
V
    

    Y
    

    so we calc the block contrast use :
    
   (cy + y) * stride + (cx + x)

    So what could be issue ? It seems FFmpeg 4.0.2 doesn’t release something (resources or its static variables to initial values after the first command)

  • Android : FFmpeg taking high memory/cpu usage causing crash

    29 janvier 2019, par dastan

    I compiled ffmpeg for android, enabled mediacodec and jni. its works but when I merge HD video 60fps, its crash the app. this ffmpeg cmd I am using.

    [-y, -benchmark, -ss, 0.0, -t, 11.541, -i, VID_HD.mp4, -filter_complex, [0:v]setpts=PTS-STARTPTS,scale=1080.0:1920.0:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=#000000, -c:v, libx264, -c:a, aac, -ac, 2, -ar, 44100, -preset, ultrafast, -strict, -2, VID_HD.ts]

    Sometimes I get these error for same cmds, but when I rerun, it works and sometimes these, if I rerun 3-4 times its restart the app. maybe because of memory is not cleaning. Help me here.

    Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
    

    
VideoKit:Error: Failed to inject frame into filter network: Out of memory
    

    
VideoKit:Error: Error while processing the decoded data for stream #0:0

    I need help in cleaning FFmpeg also when execution finished and I call my run(FFmpeg cmds) method for next video encoding it restart the app, I am suspecting because of memory usage.
