There isn't a convenient way to change the logo but it is possible if you compile the server from source.
Create a directory to store your logo and in order to complete what you are asking you need your logo saved in two different sizes and two different formats:
Large = 102px Height x 120px Width
Small = 48px Height x 41px Width
and you need them saved in both PNG and jpg.
Name your image outputs like:
png_sm.png
png_lrg.png
jpeg_sm.jpg
jpeg_lrg.jpg
There is a great piece of code on sourceforge that does all the hard work and formatting for you.
sourceforge-code-snippet
Create a empty file conversion.c and this content:
/* 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);
}
now compile it:
gcc conversion.c
Instead of doing all files individually use a bit of bash, convert.sh:
./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
Make it executable chmod +x convert.sh and run it ./convert.sh
You will see copies of your logo with a .hex just copy and paste the their content into the appropriate places of the icons.c file located in the root directory of miniDLNA source folder.
Build and run :)
I have found that the dependencies needed to build miniDLNA successfully are:
sudo apt install autoconf g++ subversion linux-source linux-headers-`uname -r` build-essential tofrodos git-core subversion dos2unix make gcc automake cmake checkinstall git-core dpkg-dev fakeroot pbuilder dh-make debhelper devscripts patchutils quilt git-buildpackage pristine-tar git yasm checkinstall cvs mercurial autopoint debhelper dh-autoreconf gcc libavutil-dev libavcodec-dev libavformat-dev libjpeg-dev libsqlite3-dev libexif-dev libid3tag0-dev libogg-dev libvorbis-dev libflac-dev
