5111540ceb Use correct clock when checking whether to write a new PCR 
The PCR clocks against the 27MHz SCR clock, so check it correctly
to avoid writing the PCR too often.

9a26173a57 Rewrite M2TS packet output 
Make sure we only write the bottom 30 bits of the PCR to the m2ts header.
Don't use floating point computation for it, and remove weird bit fiddling
that messes up the PCR in a way I can't find any
justification/documentation for.

Don't accidentally lose PCR packets from the output.

Fix the description for the m2ts-mode property so it's clear it's a flag,
and which setting does what.

d2e1f1bdc6 camerabin2: Only mark video capture as finished after EOS 
Instead of probing the videosink sinkpad for passing EOS, better
to wait for EOS from the bus.

This makes sure the filesink has already processed it and is
ready to close the file. This is used to notify applications
that camerabin2 is idle and can be shut down.

6a686316d5 basecamerasrc: camerabin2: wrappercamerabinsrc: Add read-only max-zoom prop 
This is not implemented in any of our real sources to which wrappercamerabinsrc

limit on the software zoom level using video{crop,scale} would be arbitrary.

6913db30f8 camerabin2: No need to force audiosrc to null on stop_capture 
Setting the audio source to null isn't needed and it could
make the EOS that is still flowing be dropped if autoaudiosrc
is used because its pads go flushing before the EOS gets pushed
from the real source.

0276663d0c mpegtsmux: fix broken pad caps refcount handling 
gst_caps_make_writable() takes ownership of the caps passed in, but
the caller doesn't own a ref to the caps here, because GST_PAD_CAPS
doesn't return a ref. Looks like the code relied on a caps leak
elsewhere for this to work properly.

18602e6e4e wrappercamerabinsrc: Avoid clearing recording caps 
When recording 2 videos in sequence with the same video-capture-caps,
the second video would get a not-negotiated error because the
src caps were being cleared without any intention of
renegotiating it back to the requested capture caps.

This patch avoids this caps reset procedure unless a new
caps was set.

3d1a7b0021 camerabin2: Force EOS on audio src 
We can't rely on audio sources pushing EOS when going PAUSED->READY
because this is a basesrc bahavior and when used inside autoaudiosrc

b56d9d3ba0 wrappercamerabinsrc: Check for downstream caps on first captures 
Use video_renegotiate and image_renegotiate booleans to make

cfc3f5e43b mpegaudioparse: Post CBR bitrate as nominal bitrate 
Even if VBR headers are missing, we can't guarantee that a stream is in
fact a CBR stream, so it's safer to let baseparse calculate the average
bitrate rather than assume a CBR stream. However, in order to make
/some/ metadata available before the requisite number of frames have
been parsed, this posts the bitrate from the non-VBR headers as the
nominal bitrate.

1a62d9374b wrappercamerabinsrc: Handle src state change to avoid losing timestamps 
Camerabin2 uses state changes to force the source to renegotiate its
caps to the capture formats. The state changes makes the source lose
its clock and base_time, causing it to stop timestamping the buffers.

We still need a proper way to make sources renegotiate its caps, so this
patch is a hack to make the source continue timestamping buffers even
after changing state. The patch works by getting the clock and base
time before doing the state change to NULL and setting them back
after putting it to PLAYING again. It also cares to drop the first
new segment after this state change.

0b4dfa685d mpegtsdemux: fix re-syncing on invalid data after seek 
Or possibly even at startup. If we couldn't find a sync within
the first few bytes, we'd just push more data into the adapter
but never discard any of the invalid data at the beginning, so
would never be able to re-sync.

b700377e22 camerabin: use private input-selector that still has "select-all" property 
The "select-all" property was removed when input-selector was moved
to core, but camerabin uses this, so make camerabin use a private
copy until a better fix is found.

e5f1cdd0e9 Revert "mpegvideoparse: fix timestamp generation" 
This reverts commit 2271608c43.

This patch needs more work so it doesn't cause grave playback
regressions (multi-second freezes) with some files that have
slightly broken timestamps but play fine everywhere else.

No need to check if camerabin is on video mode if it isn't on
image mode as those are the only 2 modes available.

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,

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).
