Hello!

I've got an exception:
Aspose.Flash.Flv.UnpackerException: Unsupported audio format
at Aspose.Flash.Flv.FLVUnpacker.ᑱ(SoundStreamBlock ऽ, SoundStreamBlock ा)
at Aspose.Flash.Flv.FLVUnpacker.ᑰ(FlashContainer ീ)

Code is easy:

using ( Stream stream = File.OpenRead( sourceFile ) )

{
     FLVUnpacker unp = new FLVUnpacker( stream );
     return unp.Unpack();

}

The file is attached above.

Hi Michael,

Our team has further investigated this issue and I would like to share with you that the video format used in the FLV file is not supported by SWF file. You can find all the supported video formats in the Video chapter of the SWF specification; the specification can be downloaded from this link. Please convert the existing FLV video to a new FLV file using any of the specified formats and then convert it to SWF.

In order to eliminate sound, currently you can remove any sound related tags from the FlashContainer object, however in our upcoming version, due at the end of this month, we're going to provide an overload of the Unpack method which will allow you to exclude the sound.

We're sorry for the inconvenience. If you have any further questions, please do let us know.
Regards,
