  • When performing an overlay operation with ffmpeg, the video at the top becomes blurry

    28 mars 2023, par Lance

    I have encountered a strange problem. When using ffmpeg provided in javacpp-presets to perform an overlay operation on two videos, if the video at the bottom is in motion, the video at the top becomes blurry. However, when I use locally compiled ffmpeg to execute the same command, there is no such problem. I have tried presets 5.x and 6.x, and the same problem occurs. Who can help me ?

    


    command :

    


    .javacpp/cache/ffmpeg-5.0-1.5.7-macosx-x86_64.jar/org/bytedeco/ffmpeg/macosx-x86_64/ffmpeg  -y -f lavfi -i color=c=black:s=1920x1080 -i a.mp4 -i b.mp4 -i c.mp4 -filter_complex "[2:v][3:v]alphamerge[alphamerge0];[1:v]scale=1920x1080[out0];[0:v][out0]overlay=enable='between(t,0.0,40.141)':x=0.0:y=0.0[overlay0];[overlay0][alphamerge0]overlay=enable='between(t,0.0,40.141)':x=0.0:y=0.0[out]" -preset medium -t 00:00:40.141 -crf 20 -vcodec h264 -map "[out]" -profile:v high -force_key_frames "expr:gte(t,n_forced*8)" out.mp4

    


    I have tried to change preset,crf,codec,profile and so on, nothing works.

  • Using ffmpeg to read mp4 file from stdin and extract image is failing with "Invalid data found when processing input"

    16 mars 2023, par jsindos

    Using ffmpeg, I'm trying to read an mp4 file from stdin, and save the last frame of the file to jpg.

    &#xA;

    cat PXL_20221118_051057924.TS.mp4 | ffmpeg -sseof -3 -i - -f mp4 -update 1 -q:v 1 last.jpg&#xA;

    &#xA;

    The command works fine when not running from stdin.

    &#xA;

    When running from stdin, an empty file is created, with the following error message :

    &#xA;

    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fcb4d0041c0] stream 1, offset 0x2eaee0d: partial file&#xA;pipe:: Invalid data found when processing input&#xA;

    &#xA;

    I've posted the full output below.
