proposed patch
uridecodebin has a whitelist of media types it will allow for use with
download buffering, which means that progressive download strategies aren't
available for other media types, which is somewhat restrictive (e.g. ogg and
matroska video aren't allowed).
Discussion on IRC showed that the main reason for this list is that some
demuxer can potentially cause a huge amount of seeks. However this shouldn't be
necessary given that sources can indicate that seeks should be avoided if
possible, so as long as demuxer properly respect the _SEQUENTIAL gst scheduling
flag this whitelist should be unnecessary.
