bpa, this was the info I needed. First, I did an external search for mp4 faad and found these SQ threads - listing them here may help others: http://forums.slimdevices.com/archive/index.php/t-77834.html http://www.readynas.com/forum/viewtopic.php?f=22&t=26302 [discussing 7.3 & 7.4] http://forums.slimdevices.com/showthread.php?82324-Playing-m4a-(AAC)-with-Squeezebox-Server [discussing 7.5] and also found the wiki entry: http://wiki.slimdevices.com/index.php/AAC [but only refers to transcoding mov files] Thanks for the link to the 7.7.2 faad system. I'm running linux but I'll look through the same tree and see what I can find. In the meantime, I'll try some transcoding on the fly. The strongest advice in those threads seemed to be: > > I was able to get AAC/M4A/MP4 file playback working perfectly with the > latest nightly build of 7.4.1 by adding the following to my > /etc/squeezeboxserver/conver.conf file : > > Code: Select all > #--------- > > mov pcm * * > # F > > [mp42aac] $FILE$ -stdout | [aac2wav] -stdin -stdout > > > mp4 pcm * * > # F > > [mp42aac] $FILE$ -stdout | [aac2wav] -stdin -stdout > > #------- > > > > And removing (commenting out) this section: > > Code: Select all > mp4 pcm * * > > # F > [faad] -q -w -f 2 -b 1 -s 44100 $FILE$ > This will transcode to wav. I'd prefer to transcode to flac on the fly. I wonder if there's an 'aac2flc' command? (I'll search.) bpa, thanks for the post, which really helped me dig out some of the historical background, as well as informing about some of the (possibly) remaining issues. I'll try some of this later during the day. regards, Atlantic ------------------------------------------------------------------------ Atlantic's Profile: http://forums.slimdevices.com/member.php?userid=44239 View this thread: http://forums.slimdevices.com/showthread.php?t=95072 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
