You'll have to edit /var/www/inc/playerlib.php.

Here's a snippet of function UpdMpdConf

Code:

       // Input                            <<< this is line 1674 more or less
       $data .= "max_connections \"128\"\n";
       $data .= "\n";
       $data .= "decoder {\n";
       $data .= "plugin \"ffmpeg\"\n";
       $data .= "enabled \"yes\"\n";
       $data .= "}\n\n";
       $data .= "input {\n";
       $data .= "plugin \"curl\"\n";
       $data .= "}\n\n";

       // Resampler
       $data .= "resampler {\n";
       $data .= "plugin \"soxr\"\n";
       $data .= "quality \"" . $samplerate_converter . "\"\n";
       $data .= "threads \"" . $sox_multithreading . "\"\n";
       $data .= "}\n\n";

I inserted a new Input Cache stanza so that this snippet reads

Code:

       // Input
       $data .= "max_connections \"128\"\n";
       $data .= "\n";
       $data .= "decoder {\n";
       $data .= "plugin \"ffmpeg\"\n";
       $data .= "enabled \"yes\"\n";
       $data .= "}\n\n";
       $data .= "input {\n";
       $data .= "plugin \"curl\"\n";
       $data .= "}\n\n";

        // Input Cache
        $data .= "input_cache {\n";
        $data .= "size \"1 GB\"\n";
        $data .= "}\n\n";

       // Resampler
       $data .= "resampler {\n";
       $data .= "plugin \"soxr\"\n";
       $data .= "quality \"" . $samplerate_converter . "\"\n";
       $data .= "threads \"" . $sox_multithreading . "\"\n";
       $data .= "}\n\n";

I stuck them there out of a perverse sense of style but I suppose they could have preceded the decoder and input stanzas.

PS - I'm unsure what the max cache value should be for 512MB RPis. Memory usage in normal operation suggests there's at least 128MB free but maybe less than 200 MB. Anyone have any thoughts?
