Re: N900 unable to play .mp4 audio files?
 

Has anyone tried MPlayer (KMplayer)?

Here are a couple posts I made about having trouble playing m4v (dunno if it is related):

Well, I'm not having trouble *playing* them...it's just seeing them inside Music Player. My m4a files play just fine if I launch them from File Manager....

I'm starting to wonder if this is a meta-data problem (ie they are listed *somewhere* in Music Player, but not under the expected album/artist/etc), and am using MussOrgsky to investigate (but can't seem to edit them).

EDIT: I was correct. All my the files are placed in '(unkonwn album)' album right at the bottom. My mistake was expecting Music Player to see that they were placed in directories named 'Artist/Album' (as in iTunes) and figure it out from there, but it seems it only uses the tags.

Hello to all,

very strange all my Music is in m4a format (eaac) due its smaller and quality rest more or less the same.
I even transform the files with different Programms and out from different Formats (Audio CD MP3 etc)
Never had a issue with the normal Media Player.

So as it has been mentioned before as it is a container Format, it can be that there is a codec used which the N900 can not understand and is not supported.

So perhaps check to transform the file into a other Format or run it over a compiler again.

I dont think there's anything known as ".mp4 Audio", theres only .mp4 video.

Re: N900 unable to play .mp4 audio files?
 

.mp4 is a container, MPEG-4 is a patented collection of methods defining compression of audio and visual (AV) digital data (wikipedia). Variations of it are used in xvid, divx, h.264 etc.


being a container, .mp4 files can contain either video, audio, or both (and more than one stream for each of them) as well as multiple subtitle streams.

I'm a fairly heavy gPodder user for podcasts, and like you I've got a bunch of podcasts that have moved from mp3 to m4a and don't work any more. The files that the built-in Media Player doesn't seem to like are the ones with changing artwork and subtitles.

There have been a number of bugs in Bugzilla for this, but I don't think it's fixed yet: Bug 6640

However, I've recently discovered that you can play these .m4a files through Panucci, with integration into gPodder too. KMPlayer also works, but has UI issues. Perhaps worth a try - I've made the switch.

so.. why mediaplayer authors used gstreamer, not ffmpeg? I had same problem related to this topic. My .m4a files includes audio in ALAC (Apple loseless audio codec, same with FLAC, and opensource too), which perfectly played by, 4ex, mplayer with ffalac. Now I have to use SMPlayer instead stock mediaplayer, it's not useful and comfort, because SMPlayer eats a lot of CPU and RAM, which on my N900 not in prosperity...
