Its not 16 bit alaw, i have to swap every 2 bytes, so i tell the audioconvert to get a sample of 16bits and swap it from 4321 to 1234. so the bytes (alaw samples) will be on the right position. I know its kinda odd, but my alaw file has the samples on the wrong order, so the bytes must be swaped, something like swap byte[0] with byte[1], byte[2] with byte[3]...and so goes on. I know i can make a element to do this, but i was trying to already use what is already done to acomplish the swaping. Its not a endianess problem, its the alaw samples that are on the wrong order, i just use the audioconvert endianess to try to swap the samples for me. <div class="gmail_quote">On Mon, Jul 13, 2009 at 2:30 PM, Michael Smith <<a href="mailto:msmith@xiph.org">msmith@xiph.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="im">On Mon, Jul 13, 2009 at 8:54 AM, Tiago Katcipis<<a href="mailto:katcipis@inf.ufsc.br">katcipis@inf.ufsc.br</a>> wrote: > I have a file that is alaw encoded, but the file has the bytes swaped, every > two bytes must be swaped so the alaw decoder can decode properly.

It also won't work because you seem to have 16 bit a-law? GStreamer's alaw decoder doesn't support that; I've never heard of it being used - are you sure it's a-law? Regardless, you'll need a special decoder. Once you have written a decoder for this format, you can make that decoder accept the endianness your data is in, so you don't need to byteswap beforehand.
