2ce4f6a8e4 mssdemux: avoid downloading not-linked streams
When a stream gets a not-linked return, it will be marked as so and
won't download any more new fragments until a reconfigure event
is received. This will make mssdemux expose all pads, but only download
fragments for the streams that are actually being used.

Relying on the pads being linked/unlinked isn't enough in this scenario
as there might be an input-selector downstream that is actually discarding
buffers for a given linked pad.

When streams are switching, the old active stream can be blocked because
input-selector will block not-linked streams. In case the mssdemux's
stream loop is blocked pushing a buffer to a full queue downstream it will
never unblock as the queue will not drain (input-selector is blocking).

In this scenario, stream switching will deadlock as input-selector is
waiting for the newly active stream data and the stream_loop that would
push this data is blocked waiting for input-selector.

To solve this issue, whenever an stream is reactivated on a reconfigure
it will enter into the 'catch up mode', in this mode it can push buffers
from its download thread until it reaches the currrent GstSegment's position.
This works because this timestamp will always be behind or equal to the maximum
timestamp pushed for all streams, after pushing data for this timestamp,
the stream will go back to default and be pushed sequentially from the main
streaming thread. By this time, the input-selector should have already
released the thread.

c4fbff50df mssdemux: fix setting codec_data when using WaveFormatEx
When using WaveFormatEx the actual codec private data is at the end of
the wav header structure, after the cbSize field, see for example the
notes at http://wiki.multimedia.cx/index.php?title=WAVEFORMATEX

The previous code was erroneously passing the whole WAVEFORMATEX
structure as codec_data.

The smoothstreaming specifications[1,2,3] always mention WAVEFORMATEX
and never smaller structures like WAVEFORMAT or PCMWAVEFORMAT, so the
buffer can assumed to be at least 18 bytes and always consuming the wav
header gives the (possibly empty) codec private data.

58072914fa hlsdemux: fix memory leak in gst_hls_demux_get_next_fragment
This patch fixes three memory leaks in hlsdemux, one that occurs
during normal operation and two that occur during error conditions.

The gst_hls_demux_get_next_fragment function calls
gst_fragment_get_buffer which increments the reference count
on the buffer but gst_hls_demux_get_next_fragment never calls unref on
the buffer. This means that the reference count for each downloaded
fragment never gets to zero and so its memory is never released.

This patch adds a call to gst_buffer_unref after the flags have been
updated on the buffer.

There is a leak-on-error in gst_hls_demux_decrypt_fragment if it fails
to download the key file. If the key fails to download, null is
returned without doing an unref on the encrypted fragment. The
semantics of gst_hls_demux_decrypt_fragment is that it takes ownership
of the encrypted fragment and releases it before returning.

There is a leak-on-error in gst_hls_src_buf_to_utf8_playlist in the
unlikely event that the gst_buffer_map fails. In the "happy path"
operation of gst_hls_src_buf_to_utf8_playlist the buffer gets an unref
before the function returns, therefore the error condition must do the
same.

42fd04ce48 dashdemux: stop fetching live fragments that don't yet exist
There is an issue for live streams where download_loop will keep
downloading segments until it gets a 404 error for a segment
that has not yet been published. This is a problem because this
request for a segment that doesn't exist will propagate all the
way back to the origin server(s). This means that dashdemux causes
extra load on the origin server(s) for segments that aren't yet
available.

This patch uses availabilityStartTime, period
and the host's idea of UTC to decide if a fragment is available to
be requested from an HTTP server and filter out requests for fragments
that are not yet available.

90020e21df dfbvideosink: port to 1.0
including the following supports and fixes:

* Create DirectFB surfaces from GstBufferPool
* Add NV12 pixel format support
* Don't use the cursor in the exclusive mode
  - EnableCusor() can be only used when the administrative mode is set
    in DirectFB 1.6.0 and later.
* Support multiple plane rendering for planar color formats
  - This accommodates the chroma plane offsets of the framebuffer
    in planar formats.
* Invoke SetConfiguration regardless of video mode setting in setcaps()
  - SetConfiguration() method should be invoked regardless of
    the result of gst_dfbvideosink_get_best_vmode(), since the two are
    unrelated.
* Disable DirectFB signal handler
  - "--dfb:no-sighandler" option is passed to DirectFBInit().
    This prevents DirectFB from trying to kill the process and allows
    GStreamer's termination sequence to proceed normally.

7f21226956 dashdemux: offset segment numbers by startNumber
For SegmentTemplate elements containing a startNumber attribute, the
`number' member of GstMediaSegments should be offset by the value of
startNumber; however, this is not currently the case. As a result, the
first URI(s) requested by the download loop will be wrong.

This commit ensures that segment numbers will be offset by startNumber
when one is present in a SegmentTemplate element.

19a45554bf dashdemux: remove incorrect timestamp scaling.
When using a SegmentTemplate element, the timestamps of the buffers
output by dashdemux are incorrect, causing problems downstream.

The reason is that GstMediaSegment start times are calculated (in
gst_mpdparser_get_chunk_by_index) by multiplying segment index by
segment duration and then scaling the result according the `timebase'
attribute from the MPD. However, the segment duration is already a
GstClockTime (i.e., it has already been scaled according to the timebase
from the MPD and converted to a nanosecond value), so multiplying it by
the segment index will give the correct timestamp without the need for
any further scaling.

ed16c9c560 hls: fix for assert failure when using encrypted HLS streams
When using an HLS encrypted stream, an assertion failure is thrown:
(gst-launch-1.0:31028): GLib-GObject-WARNING **: cannot register
existing type `GstFragment'

(gst-launch-1.0:31028): GLib-CRITICAL **: g_once_init_leave: assertion
`result != 0' failed

Eventually tracked this down to the call gst_fragment_new()
in function gst_hls_demux_decrypt_fragment.

The GstFragment class is defined in ext/hls/gstfragment.c and in
gst-libs/gst/uridownloader/gstfragment.c. Having two class definitions
with the same name causes the assert failure when trying to allocate
GstFragment. Deleting the version from hls and editing the
Makefile.am solves this assert failure.

For the later, dashdemux should wait a little before attempting another

5ad2a2d161 dashdemux: Change first fragment selection for live streams
When dashdemux selects its first fragment, it always selects the
first fragment listed in the manifest. For on-demand content,
this is the correct behaviour. However for live content, this
behaviour is undesirable because the first fragment listed in the
manifest might be some considerable time behind "now".

The commit uses the host's idea of UTC and tries to find the
oldest fragment that contains samples for this time of day.

ef66e39d03 eagl: fix handling of surface dimension changes
Detect when the eagl surface changed its dimension (when the user rotates
the device for example) and adapt the egl internals to draw to that,
preventing that ios resizes the image again when drawing.

This is particularly harmful when eagl would scale down a image
to draw and the ios screen would scale it back up because the
surface is now bigger than when the element was configured.

39924c60a1 dashdemux: remove buffering message emission from dashdemux
dashdemux shouldn't emit the buffering message as that can pause
the pipeline. It has no proper knowledge of the downstream buffering
status so it can pause the pipeline when it isn't necessary. It should
have an internal buffer for downloading the streams ahead of playback,
but that shouldn't make it able to stop the pipeline for buffering.

A particular case in which this is bad is when a pad switch happens
(changing bitrates for example), the new pads dashdemux creates
will get linked to demuxers and new queues will be created,
these queues are initially empty and dashdemux will quickly
drain its buffers by pushing them to those queues. So it
would have no more buffers internally and would emit a
buffering message with a low ratio, causing the pipeline
to pause when it wouldn't be necessary.

9387365fc9 dashdemux: reworked the API to retrieve fragment timestamp, fragment duration and media presentation duration
This was necessary to support variable-duration Fragments.

in the new API:
- gst_mpd_client_get_current_position returns the timestamp of the NEXT fragment to download;
- gst_mpd_client_get_next_fragment_duration returns the duration of the next fragment to download;
- gst_mpd_client_get_media_presentation_duration returns the mediaPresentationDuration from the MPD file;

also there is a new internal parser function:
- gst_mpd_client_get_segment_duration extracts the constant segment duration from the MPD file
(only used when there is no SegmentTimeline syntax element in the current representation)

In gst_mpd_client_get_next_fragment, we set the timestamp/duration of the fragment just downloaded
copying the values from the corresponding GstMediaSegment.

0abd777257 dashdemux: complete support for Media Presentations with several Periods
- Periods are played in sequence, from PeriodStart to PeriodEnd
- seamless switching from one Period to the next one works fine;
- the 'new-segment' generation is broken, so if we need to switch pads for a new Period there is a crash;

9d09e99ebe mpdparser: initial support for Media Presentations made of several Periods
- build a list of the available Periods with their start and duration time
- add the list of GstStreamPeriod in the GstMpdClient data struct
- remove cur_period from GstMpdClient and introduce an API to get the current GstStreamPeriod
- several API clean-ups

362b5e9446 mpdparser: add support for SegmentTimeline syntax elements
build the list of segments to be played using the SegmentTimeline syntax, if present
bugfixes:
- for dynamic MPD files, when mediaPresentationDuration is not present use minimumUpdatePeriod instead
- do not add a spurious '$' when building an URL from a template like "$Bandwidth$/init.mp4v"
- introduce gst_mpd_client_add_media_segment() to avoid code duplication

b580ee8cd7 dashdemux: fix playing of single-segment media streams
other fixes:
- fixed a buffering bug: now we stop buffering when we reach the end of manifest
- now gst_mpd_client_get_target_duration() always returns a valid duration
(in case of single-segment streams, we return either Period duration or mediaPresentation duration)
