Hi Wim,

I don't know why fdsink is not supposed to be used with seekable file
descriptors.
Can you explain it ?

And I think that we frequently need use fdsink by seekable file descriptors.
For example:
alsasrc ! 'audio/x-raw-int, rate=(int)8000, channels=(int)1,
endianness=(int)1234, width=(int)16, depth=(int)16, signed=(boolean)true' !
wavenc ! fdsink fd=xx

The plugin wavenc will use the last buffer to update the file header of wav.
If fdsink don't support seekable file descriptors, the wav will have one wrong
header in this pipeline.


Thanks,
lei.wang
