743b4677a2 mpeg4videoparse: Use gst_bit_reader_skip to skip more than 32 bits. 
GET_BITS is a macro for gst_bit_reader_get_bits_uint32, which cannot
read more than 32 bits and will fail in this case where it is called
to read 79 bits. Since we want to skip those bits, gst_bit_reader_skip
is more appropriate in this case.

2e28fe2e18 camerabin2 remove redundant viewfinder-colorspace and viewfinder-scale 
camrabin2 connects a viewfinderbin on "vfsrc". viewfinderbin is made of:
   vfbin-csp ! vfbin-videoscale ! videosink.

we should either remove csp/videoscale from wrappercamerabinsrc (as
done in this patch) or we should get rid of viewfinderbin altogether.

7e069060b3 camerabin2: Synchronize clock and base time to audiosrc

Robert Swain
7f720ed606 camerabin2: Prevent audio source from providing clock 
The audio source inside camerabin2 is put to READY and back to
PLAYING when starting capture, causing the pipeline to lose its
clock. As camerabin2 isn't put to PAUSED->PLAYING again during
this, a new clock isn't selected for elements.

2609427ada camerabin2: Add flags prop to toggle encodebin conversion elements 
A flags property has been added to encodebin to toggle whether the
conversion elements (ffmpegcolorspace, videoscale, audioconvert,
audioresample, audiorate) are created and linked into the appropriate
branches of encodebin.

Not including these elements avoids some slow caps negotiation and
allows the first buffers to flow through encodebin much more quickly.
However, it imposes that the uncompressed input is appropriate for the
target profile and elements selected to meet that profile.

dae8d8fd5a camerabin2: Prepare audiosrc before start-capture 
If we bring the audio source up to the PAUSED state before emitting the

afee3b0301 camerabin2: Remove redundant elements

necessary and as such can be removed.

5572e63858 hlsdemux: Send NEWSEGMENT events

Here we push a GST_FORMAT_TIME newsegment, and whenever possible we
try to indicate the proper start time.

This allows downstream elements to relay the start/time values properly
to the sinks, allowing better stream switching.

57279cdd24 tsdemux: Refactor stream/program removal 
The program_stopped vmethod was called before stream_removed vmethod

we just remove the program_stopped vmethod and do everything in the
stream_removed one.

Also, make sure we flush out all pending data before sending EOS.

cbc0a2f056 mpegtsbase: Prevent stack gardening by using the right type 
stream_type is stored as guint inside the GstStructure but was retreived
using valist with a pointer to guint16. This would cause stack gardening
when code is compiled without optimisation (e.g. in -O0 the compiler wont
pad the stack to optimise out required mask).

976f4b0bbf hsldemux: Handle change of media types 
When switching bitrates, we might end up switching to a different
media-type (like from aac to/from mpeg-ts).

For this switch to behave properly in decodebin2, this patch adds:
* dynamic source pads (which will be added/removed whenever a stream
  media type changes
* re-checking the fragment media type whenever we switch to a different
  playlist

046af98b30 pcapparse: fix SLL parsing 
The current code is not checking for ethernet type, as it's supposed to,
but link layer device type and it's hard-coded to only accept dumps from
ethernet (ARPHRD_ETHER; 1). We don't care where the dump was fetched
from (wlan, 3G, etc.)

What we care about is the that the ethernet type is IP (ETHERNET_IP;
0x800), which is clearly field 14:

http://www.tcpdump.org/pcap3_man.html

And do a bit of cleanup.

a34ea4aaae camerabin2: If location is NULL do not encode images 
Using a NULL string for location means that the application
doesn't want the image to be encoded, but wants to receive

displaying to the user before it choses to encode or take another
picture in avatar capturing scenarios.

e19a488bce camerabin2: Set tagsetters to merge replace mode 
The default for tagsetters is to use merge keep mode, so tags
would never be replaced and all captures would have the same tags.

This commit watches all elements added into encodebin and sets
all tagsetters to merge replace mode

f31554bc4f camerabin2: Send serialized custom events for filename changes in image sink 
Using serialized custom events for switching image capture saving
location makes camerabin2 save each capture correctly to the location
that was set during the moment start-capture was called, and not
the moment the filesink was writing to disk.

This prevents captures to be overwriten by racyness among start-capture
and setting location for images.

a33eae1a65 camerabin2: No need to change state of the whole image branch

the whole branch.
