I have segmentation fault on playing flac-to-wav transcoded tracks.
Configuration section (default.cfg):
<file ext="flac">
<type>AUDIO_ITEM</type>
<mime_type>audio/x-flac</mime_type>
<transcode enabled="true">
<ext>wav</ext>
<mime_type>audio/mpeg</mime_type>
<dlna>WAV</dlna>
<http_encoding>stream</http_encoding>
<decoder>flac</decoder>
<encoder>wav</encoder>
<samplerate>44100</samplerate>
</transcode>
</file>
Audioplayer used:
1. software player: Windows Media player 12 in Windows 7
2. software player: Foobar2000 v.1.1.1 + foo_upnp 0.99.27 in Windows 7
3. hardware player: Yamaha RX-V3800 network receiver
4. hardware player: Dune BD Prime 3 network media player

Fuppes server:
1. compiled and running under FreeBSD 7.3
2. compiled (MinGW) and running under Windows7

In all cases playback begins and crash after some seconds

    confirmed on 32bit gentoo, SVN-680, gcc 4.4.4

    the correct device config should look something like this

    58 <file ext="flac">
    59 <type>AUDIO_ITEM</type>
    60 <mime_type>audio/x-flac</mime_type>
    61 <transcode enabled="true">
    62 <ext>wav</ext>
    63 <mime_type>audio/L16</mime_type>
    64 <dlna>WAV</dlna>
    65 <http_encoding>chunked</http_encoding>
    66 <decoder>flac</decoder>
    67 <encoder>wav</encoder>
    68 <!--<bitrate>192</bitrate>-->
    69 <samplerate>44100</samplerate>
    70 </transcode>
    71 </file>

    (that is, audio/mpeg in the original bug report is definitely wrong)

    Still, it crashes on me as well.

    Оf course!
    I replaced "audio/mpeg" to "audio/wav", but it not resolve problem.
    Playback begins and after some seconds program crashed with segmentation fault.
    u-voelkel, please write correct transcoding from flac-to wav!!!!
