miniDLNA Icon

Create Custom Icon

Create a custom icon for your server.

Clone miniDLNA

Clone the repository for miniDLNA since it must be built from source if you want this glorious feature.

git clone git://git.code.sf.net/p/minidlna/git minidlna-git

Create Files

Create a directory for your icons mkdir ~/minidlna-icons. You need to supply 2 sizes and 2 formats of the same icon that you'd like to use.

Size	Height	Width
Large	102px	120px
Small	48px	41px

The naming convention is important for the script to run successfully.

png_sm.png
png_lrg.png
jpeg_sm.jpg
jpeg_lrg.jpg

Write C Program

User hiero over on SourceForge posted a simple C program to convert the images to the proper hex values.

Create a conversion.c file in your icon directory.

/* convert icon data for icons.c" */
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
    int i, c;
    FILE *rfp, *wfp;
    if (argc < 3) {fprintf(stderr, "Usage: %s inputfilename outputfilename\n\n", argv[0]); exit(1);}
    rfp = fopen (argv[1], "rb");
    if (rfp == NULL) {fprintf(stderr, "cannot open \"%s\"\n", argv[1]); exit(1);}
    wfp = fopen (argv[2], "wb");
    if (wfp == NULL) {fprintf(stderr, "cannot create  \"%s\"e\n", argv[2]); exit(1);}
    for (; ;) {
        fprintf(wfp, "             \"");
        for (i=0; i<24 ; i++) {
            c = fgetc(rfp); if (c == EOF) break;
            c = fprintf(wfp, "\\x%02x", c); if (c<0) goto end;
        }
        fprintf(wfp, "\"\n");
        if (c == EOF) break;
    }
end:
    fclose(rfp);
    fclose(wfp);
    exit(0);
}

Compile

Compile your C program gcc conversion.c

Bash

In the same directory as the images and your new C program, make a shell script.

convert-images.sh

#!/bin/bash

./a.out jpeg_lrg.jpg jpeg_lrg.jpg.hex
./a.out jpeg_sm.jpg jpeg_sm.jpg.hex
./a.out png_lrg.png png_lrg.png.hex
./a.out png_sm.png png_sm.png.hex

bash convert-images.sh copy and paste the content from the .hex output of each icon file, and replace the original in the icons.c file that resides in the the cloned miniDLNA folder.

Recompile miniDLNA

.autogen.sh

./configure

make

sudo make install
(there is a recommendation to use `sudo checkinstall` instead.)
