216189ea36 rtpvp8depay: Accept packets with only one byte of data

0bee149c74 rtpvp8pay: Treat the frame header just like any other partition

information is another partition. This saves special-casing it later in
the actual packetizing code.

d0b942980e videoparsers: add h264parse 
Functionally equivalent to (legacy)h264parse and re-uses the latter's low
level NAL parsing, but otherwise based on GstBaseParse, and replacing
some property configuration with caps negotiation.

Implement previewing functionality using 2 properties. A boolean

GstCaps (preview-caps) to provide the desired preview caps.

image to a pipeline to adapt it to the required caps before posting.

but never discard any of the invalid data at the beginning, so
would never be able to re-sync.

07279bac7b camerabin: mode can be only image or video 
No need to check if camerabin is on video mode if it isn't on

Additionally, if mode gets corrupted somehow and would be neither
image or video it would cause a null pointer dereferencing some
lines of code below, so this is safer.

91b7f2d99e v4l2camerasrc: Implement video capture 
Implements video capture on v4l2camerasrc by using the mode property,
when mode is set to video, the pad probe pushes a new segment
and starts pushing buffers on the pad, when it the property is
sent back to preview, the pad probe pushes an EOS and stops
pushing buffers.

This is controlled by a Recording State variable, that is protected
by the GST_OBJECT_LOCK. I don't think locking for every buffer is
nice, so we could find an alternative lockless way here.

a203ad1aab dvbsuboverlay: Fix more of the blending, so it looks quite good now 
* libdvbsub gives us alpha channel already, not transparency level, so
don't do another "alpha = 255 - alpha", this is done by libdvbsub.
* Fix alpha channel handling in interpolation - assrender had an additional
1bpp alpha bitmap as a possible mask, we don't. So don't use the palette
index array as alpha values; bug from quick code porting long ago to
changing pixel colors (assrender has a single pixel color for whole
regions or something, unlike dvbsub, which has indexed colors).
* Don't forget to reassign our YUV and other local pixel color variables
after shifting to work on the bottom part of a 2x2 subsample block, or
it's obviously very blocky.

Remaining issues in blending:

* Should probably be interpolating or doing something else useful with the
resulting U and V channels, so that most of the source pixel UV values would
actually be actually cared about, except for just one out of possibly four.

* Don't convert AYUV to ARGB in libdvbsub, and then back from ARGB to AYUV in
dvbsuboverlay for no reason

* Re-factor the whole thing to something more like textoverlay blending
* Related to that, perhaps cache the current spu in a good format for quick
blending on each frame, after which the more often called blending parts
might become more straightforward

4a68decb52 dvbsuboverlay: Work with GstClockTime instead of PTS for subtitle timing 
Abuse libdvbsub PTS tracking to just store our running time in it, to get
it back in the callbacks. As GStreamer does its own PTS handling behind our
back (especially for video), we should just sync with video per running time,
not try to do it with PTS, which doesn't seem well accessible for video chain.
We can later relabel dvb-sub.c pts naming convention if wanted, it's just
passing along guint64 values, which GstClockTime fortunately is too.

The current idea is to collect the regions returned by the callback into
a FIFO buffer and pop and pre-render the top one into a separate
quick-to-blend cached format, which is then appropriately blended in the
video chain until the next one on top of the stack reaches the video chains
running time (or the fallback timer hits).

1db547f0b6 gstmpegtsdemux: add temporary **HACK** for dvb subs testing so dvbsuboverlay gets whole packets 
<tpm> leio, what's the mpegts demux hack about?
<leio> my libdvbsub code can't handle cut packets
<leio> so the hack instructs the demuxer to gather full packets before pushing down, but it applies that to more PES packet types than just dvbsub, but I'm not sure if that's a bad thing
<leio> either way, needs a cleaner solution, either in demuxer, or I need to handle cut packets
<tpm> ok, but really it should be fixed in the overlay, right?
<tpm> or a parser be inserted
<leio> the problem is that I don't know from the first packet beforehand if it is a cut one or no
<leio> not
<leio> err, first buffer
<leio> just when I receive the next one I see if it has a valid timestamp on it or not
<leio> so I can't very well queue it up in the chain either, I might be blocking the very last subtitle for no reason or something
<tpm> but you could just drop/ignore packets until you find one, right?
<leio> find what?
<tpm> a complete packet?
<leio> the problem isn't that they aren't complete
<leio> the problem is that they are cut across multiple GstBuffers by the demuxer without the hack
<tpm> sure, I understand that
<tpm> but you can't easily determine if a GstBuffer contains he start fragment of a packet or not?
<leio> I guess I could parse the packet and see if its length is enough, just like the libdvbsub code eventually does too
<leio> I can, it has a timestamp if it's the first chunk
<leio> I just never know if I need to wait for more, without some parsing
<tpm> ah ok
<leio> while the demuxer could just give me an uncut one in the first place
<leio> like it always does for program streams
<leio> that gather_pes is always set in gstmpegdemux, but not in gstmpegtsdemux

As imgbin_finished() is scheduled from g_idle_add, it might

counter.

This patch refactors imagebin element creation and linking into separate functions,
and adds re-using also for imagebin internally created elements.

So this refactoring allows creating imagebin elements already in NULL state when
application sets the image mode, and next state change from NULL to READY will be faster.
This reduces first capture latency.

Earlier the elements were both created and linked in NULL to READY state change.

68d5ab1a1d qtmux: optionally create fragmented file 
In this mode, an initial empty moov (containing only stream metadata) is written,
followed by fragments containing actual data (along with required metadata).
New fragments are started either at keyframe (if such are sparse) or when
property configured duration exceeded.

Based on patch by Marc-André Lureau <mlureau@flumotion.com>

Fixes #632911.

b11f737096 mpegtsparse: fix handling of TOT and TDT sections. Fixes #635281. 
TDT and TOT sections, with PID=0x14, doesn't extend to several packets
and the section filter is not needed here and shouldn't be used at all
for these tables because the have a different structure.
For example, TDT tables were not parsed for odd hours because this bit
is the 'current_next_indicator' bit for the other sections, and the table
was discarded.

9b6439a36c baseparse: enhancements for timestamp marked framed formats 
That is, as such formats allow subclass to extract position from frame,
it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.

Fixes #631389.

if there is any capturing/saving/encoding going on in camerabin. If
not, it is safe to set it to NULL and release resources without

"ready-for-capture" changes before the 'image-done' signal, so
the application can be notified that it can do a new capture
even before the previous one has finished encoding/saving.
