  • CANNOT LINK EXECUTABLE error with required libs loaded. How to link them properly ? [duplicate]

    11 septembre 2019, par dentex

    This question already has an answer here :

    edit : I’m aware of the possible duplicate, but the answer it’s not directly applicable. I’m using ProcessBuilder and not Runtime.getRuntime().exec :

    public int execProcess(List<string> cmds, ShellUtils.ShellCallback sc) {    
    
    StringBuilder cmdlog = new StringBuilder();
    
    for (String cmd : cmds) {
    
         cmdlog.append(' ');
    
    }
    
    Utils.logger("v", cmdlog.toString(), DEBUG_TAG);
    

    
    ProcessBuilder pb = new ProcessBuilder();
    
    pb.directory(mBinFileDir);
    
    pb.command(cmds);
    

    
    Process process = null;
    
    int exitVal = 1; // Default error
    
    try {
    
        process = pb.start();
    

    
        StreamGobbler errorGobbler = new
    
        StreamGobbler(process.getErrorStream(), "ERROR", sc);
    

    
        StreamGobbler outputGobbler = new
    
        StreamGobbler(process.getInputStream(), "OUTPUT", sc);
    

    
        errorGobbler.start();
    
        outputGobbler.start();
    

    
        exitVal = process.waitFor();

    I have two versions on FFmpeg compiled for android : with and without liblame enabled.

    When I load in /data/data/&lt;>/app_bin/ the FFmpeg binary compiled with NO lame support, it extracts audio from video without an issue. But when I use the one with lame support enabled, I get the error below into the log.

    Required libs, also compiled for android, are correctly loaded when shipped into the libs project folder with System.loadLibrary("lame").

    I was wondering if there is something else to do in order to properly make the FFmpeg binary find the libs.
    Those are the same libs given to the NDK to build the FFmpeg binary.

    I’m not attaching code because it’s fairly straightforward :

    • download the FFmpeg binary (it’s not shipped with the app) ;
    • copy the binary from the download folder to /data/data/&lt;>/app_bin/ ;
    • chmod 755 ;
    • execute from there and read the output.

    Please comment if something else is required.

  • lavfi : replace link.closed by link.status.

    lavfi : replace link.closed by link.status.

    The status field can carry any error code instead of just EOF.
    
Also only update it through a wrapper function and provide a timestamp.
    
Update the few filters that used it directly.
