43fea50c8a smoothstreaming: pass width, height, channels and rate as integer
g_ascii_strtoull() returns a long long integer, but we need to
pass a normal int to gst_structure_set() for fields of G_TYPE_INT,
so cast appropriately.

210f6c510c mssdemux: replace gst_value_deserialize with simpler function
The deserialization was only used to convert hex strings into
GstBuffers. Replace gst_value_deserialize with a simpler, direct
function.

255eb4b161 mssdemux: use streams bitrate individually
connection setup times seem to matter when measuring the download
rate of different streams. Streams with longer fragments have a
*relatively* lower connection setup time and achieve higher bitrates.

Using the average seems unfair here, so use each stream's measured bitrate
to select its best quality option.

ea5f2718bf mssdemux: make codec private data from manifest attributes with AAC-LC
When the codec is AAC-LC, some server implementation (e.g. Microsoft IIS) doesn't add the CodecPrivateData attribute. The element needs to re-create the codec data from the Quality Level attributes (channels and sampling rate).

aa1713068a mssdemux: implement live streams handling
Live streams force the demuxer to keep reloading the Manifest from
time to time, as the new fragments are being added as they are recorded.
The demuxer should also try to keep up and detect when it had to skip
fragments, marking the discont flag when that happens.

Curiously, the spec doesn't seem to mention when/how a live stream is supposed
to end, so keep trying downloads until the demuxer errors out.

21872e78b8 mssdemux: fix issue on fragment timestamping parsing
Use guint64 as the fragments can start at very high numbers,
specially on live streams

b9aec0ad0d mssdemux: add connection-speed property
This speed limits the maximum bitrate of streams. Currently it
is only read when starting the pipeline, but it should be used
for switching bitrates during playback to adapt to network
changes.

4b6900999a mssdemux: add an 'active' flag to manifest stream
mssdemux should set the streams it has exposed as active so that
the manifest won't use the non-active streams to compute total bitrates
or providing fragments

cb7e3d1f3b mssdemux: initial implementation of seek event handling
Adds basic handling for seek in time events. Needs to cooperate
with the downstream qtdemux so that it forwards the seeks and
the corresponding newsegments

and report it upstream.

3f15c9b05a mssdemux: add timescale to the caps
This is important for downstream to properly timestamp the samples

The default value is 10000000, but this can be set in the stream
or at the top-level manifest entry

ca4e5c34cb smoothstreaming: refactor structure names and implement url fetching
Use shorter names for the MSS manifest helper structure and functions.

Also continues the implementation of the stream fetching and pushing loop.
Now it uses the base url correctly and already fetches and pushes the fragments
downstream
