  • Android FFMPEG command line for video filter

    4 février 2014, par user2568369

    I am using following command to add retro effect in video.

    String[] ffmpegCommand = {"/data/data/com.mobvcasting.mjpegffmpeg/ffmpeg", "-r", ""+p.getPreviewFrameRate(), "-b", "1000000", "-vcodec", "mjpeg", "-i", Environment.getExternalStorageDirectory().getPath() + "/com.mobvcasting.mjpegffmpeg/frame_%05d.jpg","-vcodec", "mjpeg", "-acodec","libfaac","-vf","curves=vintage", "-qscale", "3", "-async", "1", "-y",Environment.getExternalStorageDirectory().getPath() + "/com.mobvcasting.mjpegffmpeg/video.mp4"};
    

    
ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();            
    

    
BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));

    but I am getting following error :

  • How to write command line argument input redirection within a bash script ?

    3 septembre 2013, par Serg ikS

    I'm putting together a bash script to run movie rendering jobs. ffmpeg expects a multi-line text file as one of the arguments for concatenation filter to join several files into one. Like this :

    ffmpeg -f concat -i mylist.txt -c copy output

    There's also an option to write it all in a single line like so :

    ffmpeg -f concat -i <(printf "file '%s'\n" A.mp4 B.mp4) -c copy Output.mp4

    How do I write the latter for into a bash script, substituting the file names from other variables ? Tryed splitting the variables, but its not the one that works. $A and $B variables contains paths to input files.

    #!/bin/bash
    
...
    
TMP_LIST=$(printf "file '%s'\n" ${A} ${B})
    
APPEND="${FFMPEG} -f concat -i <<< {${TMP_LIST}} -c copy ${OUTPUT}"
    
# run the concatenation:
    
$APPEND

  • avformat/subtitles : add a next line jumper and use it.

    8 septembre 2013, par Clément Bœsch
    avformat/subtitles : add a next line jumper and use it.

    This fixes a bunch of possible overread in avformat with the idiom p +=
    
strcspn(p, "\n") + 1 (strcspn() can focus on the trailing ’\0’ if no
    
’\n’ is found, so the +1 leads to an overread).
    

    Note on lavf/matroskaenc : no extra subtitles.o Makefile dependency is
    
added because only the header is required for ff_subtitles_next_line().
    

    Note on lavf/mpsubdec : code gets slightly complex to avoid an infinite
    
loop in the probing since there is no more forced increment.
