Audio problem with xvid encoding for SmartMovie Player (PDA)

[thoughton]

Hi Major,

I'm trying to encode xvid movies for a PDA (in 'smartmovie' format). My test source movie is a PAL mpeg1 with 44.1kHz audio. I want to output xvid at 272x208 with mp3 audio. The settings I'm using are:
Video: xvid(.avi) codec, 140kbit/s, 272x208, 12.5fps
Audio: mp3, 16kbit/s, 11025Hz, Stereo, CBR

However my output has no audio track. And when I check info in QTPlayer the annotation is 'MEncoder dev-CVS blahblahblah'.

I ran the conversion again to try and extract the audio I wanted, so this time I unchecked 'encode video'. However it again produced a video file with no audio (same size file, with the same MEncoder annotation)!
(I did this step twice to make sure I did definitely uncheck 'encode video'!)

BUT, If I change the audio bitrate to 32kbit/s the output file has an audio track! And the movie annotation is now 'DivX AVI Importer'! However my audio is still 44.1kHz instead of 11.025kHz (Smartmovie Player can play this, but the audio is double the size from the higher bitrate - would like to avoid this).

I've been able to work around it by demuxing my source movie and encoding the mp2 audio separately. If I do that I can (using the same settings as above! but unchecking encode video) produce a 16kbit/s 11.025kHz mp3 audio track which I can then remux with my xvid video. This produces a file the Smartmovie Player can play.

Is there a setting I can change to correctly produce the 11.025kHz 16kbit/s audio without demuxing and remuxing each time?

I've attached two logs (one produces no audio, one produces audio but high bitrate I want to avoid and also has wrong sampling rate), hope they are useful!

Tim

By the way, this is all with ffmpegX 0.0.9h

Never tried Smartmovie. Is there an advantage to it vs. Pocket MVP or the new Betaplayer? That is what I use to play xvid movies (with Ogg audio) on my PDA. If you want to try them out here is a temporary link to Betaplayer's download site (corecodec.org is down) They are both Freeware, but I feel Betaplayer is better than PMVP.

FWIW here is a guide I whipped up for encoding for it.

I think some of those apps are for PocketPC only? I'm using SmartMovie on a Symbian OS phone (SE P800). I'm only using it because it has full screen playback and the required format is somewhat open (although the exact required specifications are a bit obscure). I just couldnt figure out how to encode the VICS video player format, and the Philips Camcoder playback is too slow on my (old) firmware.

Betaplayer has a smartphone build.

Well, after some googling I found the author's homepage (corecodec seems to be broken) and got the smartphone build. Fired up VPC and ran it, but it appears to be for pocketpc-based smartphones.
