c2ae981e6d mssdemux: rewriting pad tasks so that buffers are pushed by ts order
Use pad tasks to download data and an extra task that gets the earlier
buffer (with the smallest timestamp) and pushes on the corresponding
pad.

This prevents that the audio stream rushes ahead on buffers as its
fragments should be smaller

fba63178fe mssdemux: some fixes to bitrate switching

da4fad2f6f mssdemux: implement bitrate switching
When connection-speed changes, signal that we might need a bitrate
switch. During the switch, a new pad group is added and the old one
is drained and removed.

New pads also need to push newsegments before starting to stream

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

529b248a89 codecparsers: ensure the debug category is properly initialized

3f15c9b05a mssdemux: add timescale to the caps

ca4e5c34cb smoothstreaming: refactor structure names and implement url fetching

f72869816c uridownloader: make cancelled state 'permanent' until a reset
When downloading and cancelling quickly the uridownloader object and the
element using it could miss the cancelled window and the uridownloader
would fetch the wrong URI and block on subsequent fetches.

This was also problematic when stopping elements, while one task would
call the cancel, another element thread could issue a new fetch_uri. As
the cancel state isn't 'permanent' this fetch_uri would block and
prevent the whole element from stopping and going to NULL.

This patch makes the 'cancelled' state permanent until a
gst_uri_downloader_reset is called. This way the element knows the
window where the uridownloader isn't active and only reactivate it when
ready.

4d4fd09a3a mpegtsmux: Fix memory leak when using prepare_func
prepare_func will allocate a new buffer to replace the original
one. Instead of using gst_buffer_replace (which causes an extra
refcount increment on the new buffer), we just unref the original
buffer.

f1a6d84a6c mpegvideoparse: don't announce incomplete source caps
Don't send any source caps yet if we're still in
drop-buffers-until-we-get-a-sequence-header mode.

Fixes transmuxing of many MPEG-TS/PS streams into
formats which require things like width, height or
codec_data on the input caps.

Also fixes issues when using playbin with decoder
sinks that want width/height etc.
