Right now the RV depacketizer plugin is found at:
datatype/rm/video/payload/depacker
It probably doesn't get built with dtdrive by default, since
using the
depacketizer in dtdrive is not a common use case.

It should work already once the depacketizer plugin is built
along with
dtdrive.

Just wondering - what is the use case for this? All the RV
depacketizer
plugin does is convert packetized RV to a raw bitstream. But
this raw
bitstream by itself is probably not that useful. We used
this
depacketizer plugin to create raw bitstream files so that
certain
decoding test tools could read a raw bitstream (rather than
having to
implement code to parse an .rm file, RV depacketization,
etc.)
<Ashish> I am evaluting it for thumbnail generation.
There is an already
existing module in S60 for decoding and receiving the
decoded frames for
thumbnail generation. This module should be able to generate
thumbnails
if input is given as depacketized frames from dtdriver.
Another option
is to use the existing renderer in such a way that it would
return the
decoded frames rather than blitting directly.
