Problems with mp4 audio

May 22, 2009 at 3:41 PM

We are using the April release of the kit on Moss 2007 with a licensed version of the encoder.  Everything seems to be working, but the file produced by the Auto Encoder will not open/play in quicktime or iTunes.  The podcasts show up, but they have an error that says they are not in a format it can play.  I looked at the mp4 file and it seems like the audio is windows audio and not aac.  Is there somewhere I can check to ensure that the encoder is using the correct audio encode settings? 

These are the settings that encoded file show up with:

Audio: Windows Media Audio 44100Hz stereo 128Kbps [Raw Audio 0]
Video: WVC1 512x288 15.00fps 1000Kbps [Raw Video 1]

 

Thanks in advance for any help!

Hi Rob,

Please make sure that you are running the SP1 of the Expression Encoder.

Are you getting the same results for the Auto Encode profiles- HardwareDeviceH264Small and HardwareDeviceH264Large?

Hi,

The About says Microsoft Expression Encoder 2 Service Pack 1 Version 2.1.1216.0 and it includes our license key. 

Yes, it happens on both H264 formats.  I reinstalled SP1 for fun today and uploaded another video.  After the encode the MP4 still has the following properties:

Audio: Windows Media Audio 44100Hz stereo 128Kbps [Raw Audio 0]
Video: WVC1 512x288 15.00fps 1000Kbps [Raw Video 1]

 

Thanks for the help!

Hey all,

I ran a manual job in the Encoder wih H264 small and the file attributes come out correct:

Video: MPEG4 Video (H264) 320x240 30.00fps [Video]
Audio: AAC 48000Hz stereo 1536Kbps [Audio]

 

So when the auto encode does it, I get Windows Audio, when expression does it with its defaults, I get AAC. *shrug*
