SOLVED: aac/m4a to rhythmbox

[Anonymous]

Hi there,

are there any known issues streaming aac/m4a from armel to x86?

server config:
– QNAP TS-209II
– debian lenny/sid
– armel

client config:
– x86 laptop
– unbuntu 8.10

Playing the same file directly on the client works as expected.

The error manifests itself as follows:
– rhythmbox (rb) connects to firefly (ff) -> ok
– rb requests stream from ff -> ok
– ff initiates the transfer -> ok
– rb plays nothing and skips to the next track -> nok

rb log with local playback: this does result in playback

I have also noticed ff reports the mimetype as being audio/m4a and gst-inspect reports audio/x-m4a. Is this a mismatch? Or doesn’t it matter?

john@new-york:~$ gst-inspect | grep aac

faac:  faac: AAC audio encoder

typefindfunctions: adts_mpeg_stream: aac

john@new-york:~$ gst-inspect | grep m4a

typefindfunctions: audio/x-m4a: m4a

ffmpeg:  ffdemux_mov_mp4_m4a_3gp_3g2_mj2: FFMPEG QuickTime/MPEG4/Motion JPEG 2000 format demuxer

Does this have something to do with this?

http://groups.google.com/group/linux.debian.bugs.dist/browse_thread/thread/532091da665908ce/af30d97947e321cb?lnk=raot

I’m using ff svn-1696 w/ rb 0.11.6. And the aac/mp4 have been produced using nearo (w/o the a) on linux (no wine).

Now it’s working 😀

Had to optimize the mp4 for streaming as in the link in my previous post suggests. After rescanning everthing worked as I expected. Optimization is performed by:

mp4creator -optimize 

Thanks for this fantastic media server!

I’d like to add this information to the wiki FAQ @ http://wiki.fireflymediaserver.org/FAQ?action=edit.

Although I am logged on the server tells me
