Hi,

The failed point in gecko is at the link as below.
http://mxr.mozilla.org/mozilla-central/source/content/media/omx/OmxDecoder.cpp#441

And the logcat show that the underlying mp3 codec didn't support 
E/XX_MP3DEC( 1083): Unsupported MP3 Layer format: 2

So this would be a POVB issue.

Hi Michael,

Could you confirm this is a POVB issue from supporting format of HW Codec?
Thanks.

Occurs on v1.1 as well.

I don't think that makes this a vendor bug. There's parts in our codebase that controls whether we can handle a codec or not.

Chris - Are there plans to support MPEG4 or MPEG2 videos?

No plans to support those that I'm aware of.

Yes, I see the same output as comment 3 on my build and it is coming from beneath Gecko.
