  • how to add overlay at the end of video without knowing time duration of video file - ffmpeg

    13 décembre 2019, par Luka mikic

    I have a bunch of video files to which I add animated overlay at the beginning of video, but I would like to add it again at the end of it t-13 seconds. This is my bash script :

    do
    
   ffmpeg -i "${f}" -i /app/logo/lower.mov -i /app/logo/logo.png -filter_complex \
    
      "[0:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:x=(1280-iw)/2:y=(720-ih)/2:color=black[bg0]; \
    
      [bg0][1:v]overlay=10:10[bg1]; \
    
      [bg1][2:v]overlay=10:10,drawtext=fontfile=/app/logo/Courier Prime.ttf:text=$(basename "${f}" | cut -f 1 -d '.'): \
    
      fontcolor=white:fontsize=25:x=256:y=h-th-130:alpha=1:enable='between(t,2,15)'" \
    
      -c:v libx264 -crf 21 -preset ultrafast "${f%.*}.mp4" -y
    
done

    Is there any way to do this ? I know how to extract the duration with FFProbe, but do not know how to add duration dynamically to a variable and then apply it to code I have.

  • String input in .bat script for ffmpeg encoder

    27 janvier 2016, par Ѕвонко Петровски

    Okay, I have this script which does batch encoding in ffmpeg. It basically calls upon ffmpeg for every file. What I want to do is to make the script ask for input and output locations before it starts executing.

    Here is the original script :

    for %%a in ("*.mp4") do "G:\ffmpeg\bin\ffmpeg" -i "%%a" -c:v libx264 -preset slow -crf 20 -maxrate 15000k -bufsize 2000k -acodec copy "newfiles\%%~na.mp4"

    Now I’d like to be able to input a string with a location for the files in he first brackets ("*.mp4") and at the end for "newfiles\%% na.mp4".

    I would presume that %% na is used to generate number orders or something but I’m not completely sure.

    I would presume that two variables/strings need to be created and then utilized by reading from keyboard. Sadly I have absolutely no experience with this. Did some c++ in school but that was that.

    Thanks in advance.

  • aacdec_ac : fix signed overflow in ff_aac_ac_update_context()

    aacdec_ac : fix signed overflow in ff_aac_ac_update_context()

    The issue is that state->cur[] is 8-bits, but a+b+1 can overflow
    
before being clipped to 0xF in the following line, causing an incorrect
    
state to be saved for the next symbol.
    

    This solves numerous bitstream desyncs, particularly when coefficients
    
with magnitude greater than 127 are sent.
