Hi,
I'm trying to make a large collection of audio files available through a
HTTP server. The collection consists of mostly Ogg Vorbis and MP3, and a
couple of files in other formats. Unfortunately, the client that's
supposed to play the files does not support any of these formats except
for MP3.
Is there any way to set up a webserver that will automatically convert
the various audio file formats to MP3?
I'm not looking for a web radio, instead each file should be accessible
individually and look just like a regular MP3 to the client. Some kind
of streaming would be nice though (so the client can start playback
before the whole file is converted/transferred).
Any suggestions how this could be done?
Thanks,
Dominic

Hi -
I know that MediaTomb at least can handle the transcoding that you
describe <http://mediatomb.cc/pages/transcoding>. It's primarily a
UPnP server rather than HTTP but it does have a HTTP interface and if
I remember right, you can listen over HTTP.

To me it looks like the HTTP interface is just meant for configuration.
I could be missing something here, but how would I access the transcoded
files via HTTP?

I'm pretty sure that one can associate an arbitrary piece of code with
a URI in any webserver worth its salt. Even good old CGI could do that
(well, that was the point of it).
About streaming I definitely don't know anything, but mplayer for
example will happily start playing after it's filled its cache (the
size of which can be given on the command line) and doesn't wait until
the whole file is downloaded.
HTH,

I'll definitely try that. Writing a small script to do the conversion is
not an issue, I'll just have to figure out how to configure the
webserver appropriately.

It's probably not actually streaming I need, just that the file transfer
starts before the conversion is finished. Not sure if there's anything
special I need to do to make sure it does, but I guess I'll find out
once everything else is in place...

Hi,
I am working on a site with some friends which among other things allows
users to upload audio files to be played using a flash based mp3 player.
We are using drupal (version 6), which is a highly flexible open source
content management system. There are probably simpler ways of doing what
you want than using drupal, but its advantage is you can use the same
system to add on loads of extra functions if and when you need them.
Drupal includes a module called media mover, which uses ffmpeg to
automatically transcode media files to the format of your choice. We are
actually using this for video transcoding and thumbnailing, but I think
it can be used for audio files as well. The only trouble at the moment
is that in the 6.x version, there are some outstanding bugs which are
currently awkward (though possible) to work around. This will probably
be cured in time (by me if no-one else...)
See potatopark.clearerchannel.org for a very early demo of the site.
There are also some sample sites on the drupal home page.

Drupal is definitely overkill for what I need at the moment, I'll first
try to get something working with a simple CGI script or similar. But of
course the requirements might change later on, so I'll keep Media Mover
in mind.

Sure, if I could write a CGI script that shelled out to an ffmpeg script
and converted videos to flv on the fly to watch in my Wii browser using
Flowplayer, converting to mp3 on the fly ought to be cake. Here's what I
wrote (word wrap will probably break up comments and make them not run):
streamasflv:
#!/bin/bash
# youtube resolution is 320x240, but wii browser works better at 480x348
time ffmpeg -i "$@" -s 468x320 -b 500k -r 24 -f flv -ar 22050 -
test.cgi:
#!/usr/bin/perl
use CGI qw(:standard);
use strict;
my $videodir = "$ENV{HOME}/Video/music-videos/need-re-encoding";
if ($ENV{PATH_INFO} =~ /\./) {
$SIG{HUP} = sub { warn("$0: got a HUP\n"); exit 0;}; # kill our child
ffmpeg process.... i hope
$SIG{TERM} = sub { warn("$0: got a TERM\n"); exit 0;}; # kill our child
ffmpeg process.... i hope
$SIG{PIPE} = sub { warn("$0: got a PIPE\n"); exit 0;}; # kill our child
ffmpeg process.... i hope
my $path = $ENV{PATH_INFO};
$path =~ s|.*/||g;
$path =~ s|\.flv$||;
die "$videodir/$path doesn't exist" unless -f
"$videodir/$path";
print header("video/x-flv");
open IN, "./streamasflv \"$videodir/$path\" |";
my $data;
while (read IN, $data, 4096) {
print $data;
}
close IN;
exit 0;
}
my $curvid;
if (param("video") ne '') {
$curvid = param("video");
}
opendir VIDS, "$videodir";
my @vids = readdir(VIDS);
closedir VIDS;
my $vidlist;
my $i;
for my $vid (@vids) {
next unless -f "$videodir/$vid";
$curvid = $vid unless $curvid;
my $bg;
if ($i++ % 2) {
$bg = "white";
} else {
$bg = "#c0c0ff";
}

I had another script that started streaming requested videos while
simultaneously queueing them for non-realtime encoding in the background,
providing better quality and allowing the user to seek within the video,
but it was kind of flaky and I never got it to where I wanted it and after
moving to a new place, never really had an occasion to watch video on the
Wii. For instant gratification and transparency, the above worked fine.
